How Did Authorities Identify the Alleged Lockbit Boss?

13 May 2024 at 07:26

Last week, the United States joined the U.K. and Australia in sanctioning and charging a Russian man named Dmitry Yuryevich Khoroshev as the leader of the infamous LockBit ransomware group. LockBit’s leader “LockBitSupp” claims the feds named the wrong guy, saying the charges don’t explain how they connected him to Khoroshev. This post examines the activities of Khoroshev’s many alter egos on the cybercrime forums, and tracks the career of a gifted malware author who has written and sold malicious code for the past 14 years.

On May 7, the U.S. Department of Justice indicted Khoroshev on 26 criminal counts, including extortion, wire fraud, and conspiracy. The government alleges Khoroshev created, sold and used the LockBit ransomware strain to personally extort more than $100 million from hundreds of victim organizations, and that LockBit as a group extorted roughly half a billion dollars over four years.

Federal investigators say Khoroshev ran LockBit as a “ransomware-as-a-service” operation, wherein he kept 20 percent of any ransom amount paid by a victim organization infected with his code, with the remaining 80 percent of the payment going to LockBit affiliates responsible for spreading the malware.

Financial sanctions levied against Khoroshev by the U.S. Department of the Treasury listed his known email and street address (in Voronezh, in southwest Russia), passport number, and even his tax ID number (hello, Russian tax authorities). The Treasury filing says Khoroshev used the emails sitedev5@yandex.ru, and khoroshev1@icloud.com.

According to DomainTools.com, the address sitedev5@yandex.ru was used to register at least six domains, including a Russian business registered in Khoroshev’s name called tkaner.com, which is a blog about clothing and fabrics.

A search at the breach-tracking service Constella Intelligence on the phone number in Tkaner’s registration records  — 7.9521020220 — brings up multiple official Russian government documents listing the number’s owner as Dmitri Yurievich Khoroshev.

Another domain registered to that phone number was stairwell[.]ru, which at one point advertised the sale of wooden staircases. Constella finds that the email addresses webmaster@stairwell.ru and admin@stairwell.ru used the password 225948.

DomainTools reports that stairwell.ru for several years included the registrant’s name as “Dmitrij Ju Horoshev,” and the email address pin@darktower.su. According to Constella, this email address was used in 2010 to register an account for a Dmitry Yurievich Khoroshev from Voronezh, Russia at the hosting provider firstvds.ru.

Cyber intelligence firm Intel 471 finds that pin@darktower.ru was used by a Russian-speaking member called Pin on the English-language cybercrime forum Opensc. Pin was active on Opensc around March 2012, and authored 13 posts that mostly concerned data encryption issues, or how to fix bugs in code.

Other posts concerned custom code Pin claimed to have written that would bypass memory protections on Windows XP and Windows 7 systems, and inject malware into memory space normally allocated to trusted applications on a Windows machine.

Pin also was active at that same time on the Russian-language security forum Antichat, where they told fellow forum members to contact them at the ICQ instant messenger number 669316.

NEROWOLFE

A search on the ICQ number 669316 at Intel 471 shows that in April 2011, a user by the name NeroWolfe joined the Russian cybercrime forum Zloy using the email address d.horoshev@gmail.com, and from an Internet address in Voronezh, RU.

Constella finds the same password tied to webmaster@stairwell.ru (225948) was used by the email address 3k@xakep.ru, which Intel 471 says was registered to more than a dozen NeroWolfe accounts across just as many Russian cybercrime forums between 2011 and 2015.

NeroWolfe’s introductory post to the forum Verified in Oct. 2011 said he was a system administrator and C++ coder.

“Installing SpyEYE, ZeuS, any DDoS and spam admin panels,” NeroWolfe wrote. This user said they specialize in developing malware, creating computer worms, and crafting new ways to hijack Web browsers.

“I can provide my portfolio on request,” NeroWolfe wrote. “P.S. I don’t modify someone else’s code or work with someone else’s frameworks.”

In April 2013, NeroWolfe wrote in a private message to another Verified forum user that he was selling a malware “loader” program that could bypass all of the security protections on Windows XP and Windows 7.

“The access to the network is slightly restricted,” NeroWolfe said of the loader, which he was selling for $5,000. “You won’t manage to bind a port. However, it’s quite possible to send data. The code is written in C.”

In an October 2013 discussion on the cybercrime forum Exploit, NeroWolfe weighed in on the karmic ramifications of ransomware. At the time, ransomware-as-a-service didn’t exist yet, and many members of Exploit were still making good money from “lockers,” relatively crude programs that locked the user out of their system until they agreed to make a small payment (usually a few hundred dollars via prepaid Green Dot cards).

Lockers, which presaged the coming ransomware scourge, were generally viewed by the Russian-speaking cybercrime forums as harmless moneymaking opportunities, because they usually didn’t seek to harm the host computer or endanger files on the system. Also, there were still plenty of locker programs that aspiring cybercriminals could either buy or rent to make a steady income.

NeroWolfe reminded forum denizens that they were just as vulnerable to ransomware attacks as their would-be victims, and that what goes around comes around.

“Guys, do you have a conscience?,” NeroWolfe wrote. “Okay, lockers, network gopstop aka business in Russian. The last thing was always squeezed out of the suckers. But encoders, no one is protected from them, including the local audience.”

If Khoroshev was ever worried that someone outside of Russia might be able to connect his early hacker handles to his real life persona, that’s not clear from reviewing his history online. In fact, the same email address tied to so many of NeroWolfe’s accounts on the forums — 3k@xakep.ru — was used in 2011 to create an account for a Dmitry Yurevich Khoroshev on the Russian social media network Vkontakte.

NeroWolfe seems to have abandoned all of his forum accounts sometime in 2016. In November 2016, an exploit[.]ru member filed an official complaint against NeroWolfe, saying NeroWolfe had been paid $2,000 to produce custom code but never finished the project and vanished.

It’s unclear what happened to NeroWolfe or to Khoroshev during this time. Maybe he got arrested, or some close associates did. Perhaps he just decided it was time to lay low and hit the reset on his operational security efforts, given his past failures in this regard. It’s also possible NeroWolfe landed a real job somewhere for a few years, fathered a child, and/or had to put his cybercrime career on hold.

PUTINKRAB

Or perhaps Khoroshev saw the coming ransomware industry for the endless pot of gold that it was about to become, and then dedicated himself to working on custom ransomware code. That’s what the government believes.

The indictment against Khoroshev says he used the hacker nickname Putinkrab, and Intel 471 says this corresponds to a username that was first registered across three major Russian cybercrime forums in early 2019.

KrebsOnSecurity could find no obvious connections between Putinkrab and any of Khoroshev’s older identities. However, if Putinkrab was Khoroshev, he would have learned from his past mistakes and started fresh with a new identity (which he did). But also, it is likely the government hasn’t shared all of the intelligence it has collected against him (more on that in a bit).

Putinkrab’s first posts on the Russian cybercrime forums XSS, Exploit and UFOLabs saw this user selling ransomware source code written in C.

In April 2019, Putkinkrab offered an affiliate program that would run on top of his custom-made ransomware code.

“I want to work for a share of the ransoms: 20/80,” Putinkrab wrote on Exploit. “20 percent is my percentage for the work, you get 80% of the ransoms. The percentage can be reduced up to 10/90 if the volumes are good. But now, temporarily, until the service is fully automated, we are working using a different algorithm.”

Throughout the summer of 2019, Putinkrab posted multiple updates to Exploit about new features being added to his ransomware strain, as well as novel evasion techniques to avoid detection by security tools. He also told forum members he was looking for investors for a new ransomware project based on his code.

In response to an Exploit member who complained that the security industry was making it harder to profit from ransomware, Putinkrab said that was because so many cybercriminals were relying on crappy ransomware code.

“The vast majority of top antiviruses have acquired behavioral analysis, which blocks 95% of crypto-lockers at their root,” Putinkrab wrote. “Cryptolockers made a lot of noise in the press, but lazy system administrators don’t make backups after that. The vast majority of cryptolockers are written by people who have little understanding of cryptography. Therefore, decryptors appear on the Internet, and with them the hope that files can be decrypted without paying a ransom. They just sit and wait. Contact with the owner of the key is lost over time.”

Putinkrab said he had every confidence his ransomware code was a game-changer, and a huge money machine.

“The game is just gaining momentum,” Putinkrab wrote. “Weak players lose and are eliminated.”

The rest of his response was structured like a poem:

“In this world, the strongest survive.
Our life is just a struggle.
The winner will be the smartest,
Who has his head on his shoulders.”

Putinkrab’s final post came on August 23, 2019. The Justice Department says the LockBit ransomware affiliate program was officially launched five months later. From there on out, the government says, Khoroshev adopted the persona of LockBitSupp. In his introductory post on Exploit, LockBit’s mastermind said the ransomware strain had been in development since September 2019.

The original LockBit malware was written in C (a language that NeroWolfe excelled at). Here’s the original description of LockBit, from its maker:

“The software is written in C and Assembler; encryption is performed through the I/O Completion Port; there is a port scanning local networks and an option to find all DFS, SMB, WebDAV network shares, an admin panel in Tor, automatic test decryption; a decryption tool is provided; there is a chat with Push notifications, a Jabber bot that forwards correspondence and an option to terminate services/processes in line which prevent the ransomware from opening files at a certain moment. The ransomware sets file permissions and removes blocking attributes, deletes shadow copies, clears logs and mounts hidden partitions; there is an option to drag-and-drop files/folders and a console/hidden mode. The ransomware encrypts files in parts in various places: the larger the file size, the more parts there are. The algorithms used are AES + RSA.

You are the one who determines the ransom amount after communicating with the victim. The ransom paid in any currency that suits you will be transferred to your wallets. The Jabber bot serves as an admin panel and is used for banning, providing decryption tools, chatting – Jabber is used for absolutely everything.”

CONCLUSION

Does the above timeline prove that NeroWolfe/Khoroshev is LockBitSupp? No. However, it does indicate Khoroshev was for many years deeply invested in countless schemes involving botnets, stolen data, and malware he wrote that others used to great effect. NeroWolfe’s many private messages from fellow forum members confirm this.

NeroWolfe’s specialty was creating custom code that employed novel stealth and evasion techniques, and he was always quick to volunteer his services on the forums whenever anyone was looking help on a malware project that called for a strong C or C++ programmer.

Someone with those qualifications — as well as demonstrated mastery of data encryption and decryption techniques — would have been in great demand by the ransomware-as-a-service industry that took off at around the same time NeroWolfe vanished from the forums.

Someone like that who is near or at the top of their game vis-a-vis their peers does not simply walk away from that level of influence, community status, and potential income stream unless forced to do so by circumstances beyond their immediate control.

It’s important to note that Putinkrab didn’t just materialize out of thin air in 2019 — suddenly endowed with knowledge about how to write advanced, stealthy ransomware strains. That knowledge clearly came from someone who’d already had years of experience building and deploying ransomware strains against real-life victim organizations.

Thus, whoever Putinkrab was before they adopted that moniker, it’s a safe bet they were involved in the development and use of earlier, highly successful ransomware strains. One strong possible candidate is Cerber ransomware, the most popular and effective affiliate program operating between early 2016 and mid-2017. Cerber thrived because it emerged as an early mover in the market for ransomware-as-a-service offerings.

In February 2024, the FBI seized LockBit’s cybercrime infrastructure on the dark web, following an apparently lengthy infiltration of the group’s operations. The United States has already indicted and sanctioned at least five other alleged LockBit ringleaders or affiliates, so presumably the feds have been able to draw additional resources from those investigations.

Also, it seems likely that the three national intelligence agencies involved in bringing these charges are not showing all of their cards. For example, the Treasury documents on Khoroshev mention a single cryptocurrency address, and yet experts interviewed for this story say there are no obvious clues connecting this address to Khoroshev or Putinkrab.

But given that LockBitSupp has been actively involved in Lockbit ransomware attacks against organizations for four years now, the government almost certainly has an extensive list of the LockBit leader’s various cryptocurrency addresses — and probably even his bank accounts in Russia. And no doubt the money trail from some of those transactions was traceable to its ultimate beneficiary (or close enough).

Not long after Khoroshev was charged as the leader of LockBit, a number of open-source intelligence accounts on Telegram began extending the information released by the Treasury Department. Within hours, these sleuths had unearthed more than a dozen credit card accounts used by Khoroshev over the past decade, as well as his various bank account numbers in Russia.

The point is, this post is based on data that’s available to and verifiable by KrebsOnSecurity. Woodward & Bernstein’s source in the Watergate investigation — Deep Throat — famously told the two reporters to “follow the money.” This is always excellent advice. But these days, that can be a lot easier said than done — especially with people who a) do not wish to be found, and b) don’t exactly file annual reports.

U.S. Charges Russian Man as Boss of LockBit Ransomware Group

7 May 2024 at 13:36

The United States joined the United Kingdom and Australia today in sanctioning 31-year-old Russian national Dmitry Yuryevich Khoroshev as the alleged leader of the infamous ransomware group LockBit. The U.S. Department of Justice also indicted Khoroshev and charged him with using Lockbit to attack more than 2,000 victims and extort at least $100 million in ransomware payments.

Image: U.K. National Crime Agency.

Khoroshev (Дмитрий Юрьевич Хорошев), a resident of Voronezh, Russia, was charged in a 26-count indictment by a grand jury in New Jersey.

“Dmitry Khoroshev conceived, developed, and administered Lockbit, the most prolific ransomware variant and group in the world, enabling himself and his affiliates to wreak havoc and cause billions of dollars in damage to thousands of victims around the globe,” U.S. Attorney Philip R. Sellinger said in a statement released by the Justice Department.

The indictment alleges Khoroshev acted as the LockBit ransomware group’s developer and administrator from its inception in September 2019 through May 2024, and that he typically received a 20 percent share of each ransom payment extorted from LockBit victims.

The government says LockBit victims included individuals, small businesses, multinational corporations, hospitals, schools, nonprofit organizations, critical infrastructure, and government and law-enforcement agencies.

“Khoroshev and his co-conspirators extracted at least $500 million in ransom payments from their victims and caused billions of dollars in broader losses, such as lost revenue, incident response, and recovery,” the DOJ said. “The LockBit ransomware group attacked more than 2,500 victims in at least 120 countries, including 1,800 victims in the United States.”

The unmasking of LockBitSupp comes nearly three months after U.S. and U.K. authorities seized the darknet websites run by LockBit, retrofitting it with press releases about the law enforcement action and free tools to help LockBit victims decrypt infected systems.

The feds used the existing design on LockBit’s victim shaming website to feature press releases and free decryption tools.

One of the blog captions that authorities left on the seized site was a teaser page that read, “Who is LockbitSupp?,” which promised to reveal the true identity of the ransomware group leader. That item featured a countdown clock until the big reveal, but when the site’s timer expired no such details were offered.

Following the FBI’s raid, LockBitSupp took to Russian cybercrime forums to assure his partners and affiliates that the ransomware operation was still fully operational. LockBitSupp also raised another set of darknet websites that soon promised to release data stolen from a number of LockBit victims ransomed prior to the FBI raid.

One of the victims LockBitSupp continued extorting was Fulton County, Ga. Following the FBI raid, LockbitSupp vowed to release sensitive documents stolen from the county court system unless paid a ransom demand before LockBit’s countdown timer expired. But when Fulton County officials refused to pay and the timer expired, no stolen records were ever published. Experts said it was likely the FBI had in fact seized all of LockBit’s stolen data.

LockBitSupp also bragged that their real identity would never be revealed, and at one point offered to pay $10 million to anyone who could discover their real name.

KrebsOnSecurity has been in intermittent contact with LockBitSupp for several months over the course of reporting on different LockBit victims. Reached at the same ToX instant messenger identity that the ransomware group leader has promoted on Russian cybercrime forums, LockBitSupp claimed the authorities named the wrong guy.

“It’s not me,” LockBitSupp replied in Russian. “I don’t understand how the FBI was able to connect me with this poor guy. Where is the logical chain that it is me? Don’t you feel sorry for a random innocent person?”

LockBitSupp, who now has a $10 million bounty for his arrest from the U.S. Department of State, has been known to be flexible with the truth. The Lockbit group routinely practiced “double extortion” against its victims — requiring one ransom payment for a key to unlock hijacked systems, and a separate payment in exchange for a promise to delete data stolen from its victims.

But Justice Department officials say LockBit never deleted its victim data, regardless of whether those organizations paid a ransom to keep the information from being published on LockBit’s victim shaming website.

Khoroshev is the sixth person officially indicted as active members of LockBit. The government says Russian national Artur Sungatov used LockBit ransomware against victims in manufacturing, logistics, insurance and other companies throughout the United States.

Ivan Gennadievich Kondratyev, a.k.a. “Bassterlord,” allegedly deployed LockBit against targets in the United States, Singapore, Taiwan, and Lebanon. Kondratyev is also charged (PDF) with three criminal counts arising from his alleged use of the Sodinokibi (aka “REvil“) ransomware variant to encrypt data, exfiltrate victim information, and extort a ransom payment from a corporate victim based in Alameda County, California.

In May 2023, U.S. authorities unsealed indictments against two alleged LockBit affiliates, Mikhail “Wazawaka” Matveev and Mikhail Vasiliev. In January 2022, KrebsOnSecurity published Who is the Network Access Broker ‘Wazawaka,’ which followed clues from Wazawaka’s many pseudonyms and contact details on the Russian-language cybercrime forums back to a 31-year-old Mikhail Matveev from Abaza, RU.

Matveev remains at large, presumably still in Russia. Meanwhile, the U.S. Department of State has a standing $10 million reward offer for information leading to Matveev’s arrest.

Vasiliev, 35, of Bradford, Ontario, Canada, is in custody in Canada awaiting extradition to the United States (the complaint against Vasiliev is at this PDF).

In June 2023, Russian national Ruslan Magomedovich Astamirov was charged in New Jersey for his participation in the LockBit conspiracy, including the deployment of LockBit against victims in Florida, Japan, France, and Kenya. Astamirov is currently in custody in the United States awaiting trial.

The Justice Department is urging victims targeted by LockBit to contact the FBI at https://lockbitvictims.ic3.gov/ to file an official complaint, and to determine whether affected systems can be successfully decrypted.

Man Who Mass-Extorted Psychotherapy Patients Gets Six Years

30 April 2024 at 09:34

A 26-year-old Finnish man was sentenced to more than six years in prison today after being convicted of hacking into an online psychotherapy clinic, leaking tens of thousands of patient therapy records, and attempting to extort the clinic and patients.

On October 21, 2020, the Vastaamo Psychotherapy Center in Finland became the target of blackmail when a tormentor identified as “ransom_man” demanded payment of 40 bitcoins (~450,000 euros at the time) in return for a promise not to publish highly sensitive therapy session notes Vastaamo had exposed online.

Ransom_man announced on the dark web that he would start publishing 100 patient profiles every 24 hours. When Vastaamo declined to pay, ransom_man shifted to extorting individual patients. According to Finnish police, some 22,000 victims reported extortion attempts targeting them personally, targeted emails that threatened to publish their therapy notes online unless paid a 500 euro ransom.

Finnish prosecutors quickly zeroed in on a suspect: Julius “Zeekill” Kivimäki, a notorious criminal hacker convicted of committing tens of thousands of cybercrimes before he became an adult. After being charged with the attack in October 2022, Kivimäki fled the country. He was arrested four months later in France, hiding out under an assumed name and passport.

Antti Kurittu is a former criminal investigator who worked on an investigation involving Kivimäki’s use of the Zbot botnet, among other activities Kivimäki engaged in as a member of the hacker group Hack the Planet (HTP).

Kurittu said the prosecution had demanded at least seven years in jail, and that the sentence handed down was six years and three months. Kurittu said prosecutors knocked a few months off of Kivimäki’s sentence because he agreed to pay compensation to his victims, and that Kivimäki will remain in prison during any appeal process.

“I think the sentencing was as expected, knowing the Finnish judicial system,” Kurittu told KrebsOnSecurity. “As Kivimäki has not been sentenced to a non-suspended prison sentence during the last five years, he will be treated as a first-timer, his previous convictions notwithstanding.”

But because juvenile convictions in Finland don’t count towards determining whether somebody is a first-time offender, Kivimäki will end up serving approximately half of his sentence.

“This seems like a short sentence when taking into account the gravity of his actions and the life-altering consequences to thousands of people, but it’s almost the maximum the law allows for,” Kurittu said.

Kivimäki initially gained notoriety as a self-professed member of the Lizard Squad, a mainly low-skilled hacker group that specialized in DDoS attacks. But American and Finnish investigators say Kivimäki’s involvement in cybercrime dates back to at least 2008, when he was introduced to a founding member of what would soon become HTP.

Finnish police said Kivimäki also used the nicknames “Ryan”, “RyanC” and “Ryan Cleary” (Ryan Cleary was actually a member of a rival hacker group — LulzSec — who was sentenced to prison for hacking).

Kivimäki and other HTP members were involved in mass-compromising web servers using known vulnerabilities, and by 2012 Kivimäki’s alias Ryan Cleary was selling access to those servers in the form of a DDoS-for-hire service. Kivimäki was 15 years old at the time.

In 2013, investigators going through devices seized from Kivimäki found computer code that had been used to crack more than 60,000 web servers using a previously unknown vulnerability in Adobe’s ColdFusion software. KrebsOnSecurity detailed the work of HTP in September 2013, after the group compromised servers inside data brokers LexisNexis, Kroll, and Dun & Bradstreet.

The group used the same ColdFusion flaws to break into the National White Collar Crime Center (NWC3), a non-profit that provides research and investigative support to the U.S. Federal Bureau of Investigation (FBI).

As KrebsOnSecurity reported at the time, this small ColdFusion botnet of data broker servers was being controlled by the same cybercriminals who’d assumed control over SSNDOB, which operated one of the underground’s most reliable services for obtaining Social Security Number, dates of birth and credit file information on U.S. residents.

Kivimäki was responsible for making an August 2014 bomb threat against former Sony Online Entertainment President John Smedley that grounded an American Airlines plane. Kivimäki also was involved in calling in multiple fake bomb threats and “swatting” incidents — reporting fake hostage situations at an address to prompt a heavily armed police response to that location.

Ville Tapio, the former CEO of Vastaamo, was fired and also prosecuted following the breach. Ransom_man bragged about Vastaamo’s sloppy security, noting the company had used the laughably weak username and password “root/root” to protect sensitive patient records.

Investigators later found Vastaamo had originally been hacked in 2018 and again in 2019. In April 2023, a Finnish court handed down a three-month sentence for Tapio, but that sentence was suspended because he had no previous criminal record.

FCC Fines Major U.S. Wireless Carriers for Selling Customer Location Data

29 April 2024 at 16:56

The U.S. Federal Communications Commission (FCC) today levied fines totaling nearly $200 million against the four major carriers — including AT&T, Sprint, T-Mobile and Verizon — for illegally sharing access to customers’ location information without consent.

The fines mark the culmination of a more than four-year investigation into the actions of the major carriers. In February 2020, the FCC put all four wireless providers on notice that their practices of sharing access to customer location data were likely violating the law.

The FCC said it found the carriers each sold access to its customers’ location information to ‘aggregators,’ who then resold access to the information to third-party location-based service providers.

“In doing so, each carrier attempted to offload its obligations to obtain customer consent onto downstream recipients of location information, which in many instances meant that no valid customer consent was obtained,” an FCC statement on the action reads. “This initial failure was compounded when, after becoming aware that their safeguards were ineffective, the carriers continued to sell access to location information without taking reasonable measures to protect it from unauthorized access.”

The FCC’s findings against AT&T, for example, show that AT&T sold customer location data directly or indirectly to at least 88 third-party entities. The FCC found Verizon sold access to customer location data (indirectly or directly) to 67 third-party entities. Location data for Sprint customers found its way to 86 third-party entities, and to 75 third-parties in the case of T-Mobile customers.

The commission said it took action after Sen. Ron Wyden (D-Ore.) sent a letter to the FCC detailing how a company called Securus Technologies had been selling location data on customers of virtually any major mobile provider to law enforcement officials.

That same month, KrebsOnSecurity broke the news that LocationSmart — a data aggregation firm working with the major wireless carriers — had a free, unsecured demo of its service online that anyone could abuse to find the near-exact location of virtually any mobile phone in North America.

The carriers promised to “wind down” location data sharing agreements with third-party companies. But in 2019, reporting at Vice.com showed that little had changed, detailing how reporters were able to locate a test phone after paying $300 to a bounty hunter who simply bought the data through a little-known third-party service.

Sen. Wyden said no one who signed up for a cell plan thought they were giving permission for their phone company to sell a detailed record of their movements to anyone with a credit card.

“I applaud the FCC for following through on my investigation and holding these companies accountable for putting customers’ lives and privacy at risk,” Wyden said in a statement today.

The FCC fined Sprint and T-Mobile $12 million and $80 million respectively. AT&T was fined more than $57 million, while Verizon received a $47 million penalty. Still, these fines represent a tiny fraction of each carrier’s annual revenues. For example, $47 million is less than one percent of Verizon’s total wireless service revenue in 2023, which was nearly $77 billion.

The fine amounts vary because they were calculated based in part on the number of days that the carriers continued sharing customer location data after being notified that doing so was illegal (the agency also considered the number of active third-party location data sharing agreements). The FCC notes that AT&T and Verizon each took more than 320 days from the publication of the Times story to wind down their data sharing agreements; T-Mobile took 275 days; Sprint kept sharing customer location data for 386 days.

Update, 6:25 p.m. ET: Clarified that the FCC launched its investigation at the request of Sen. Wyden.

Russian FSB Counterintelligence Chief Gets 9 Years in Cybercrime Bribery Scheme

22 April 2024 at 16:07

The head of counterintelligence for a division of the Russian Federal Security Service (FSB) was sentenced last week to nine years in a penal colony for accepting a USD $1.7 million bribe to ignore the activities of a prolific Russian cybercrime group that hacked thousands of e-commerce websites. The protection scheme was exposed in 2022 when Russian authorities arrested six members of the group, which sold millions of stolen payment cards at flashy online shops like Trump’s Dumps.

A now-defunct carding shop that sold stolen credit cards and invoked 45’s likeness and name.

As reported by The Record, a Russian court last week sentenced former FSB officer Grigory Tsaregorodtsev for taking a $1.7 million bribe from a cybercriminal group that was seeking a “roof,” a well-placed, corrupt law enforcement official who could be counted on to both disregard their illegal hacking activities and run interference with authorities in the event of their arrest.

Tsaregorodtsev was head of the counterintelligence department for a division of the FSB based in Perm, Russia. In February 2022, Russian authorities arrested six men in the Perm region accused of selling stolen payment card data. They also seized multiple carding shops run by the gang, including Ferum Shop, Sky-Fraud, and Trump’s Dumps, a popular fraud store that invoked the 45th president’s likeness and promised to “make credit card fraud great again.”

All of the domains seized in that raid were registered by an IT consulting company in Perm called Get-net LLC, which was owned in part by Artem Zaitsev — one of the six men arrested. Zaitsev reportedly was a well-known programmer whose company supplied services and leasing to the local FSB field office.

The message for Trump’s Dumps users left behind by Russian authorities that seized the domain in 2022.

Russian news sites report that Internal Affairs officials with the FSB grew suspicious when Tsaregorodtsev became a little too interested in the case following the hacking group’s arrests. The former FSB agent had reportedly assured the hackers he could have their case transferred and that they would soon be free.

But when that promised freedom didn’t materialize, four the of the defendants pulled the walls down on the scheme and brought down their own roof. The FSB arrested Tsaregorodtsev, and seized $154,000 in cash, 100 gold bars, real estate and expensive cars.

At Tsaregorodtsev’s trial, his lawyers argued that their client wasn’t guilty of bribery per se, but that he did admit to fraud because he was ultimately unable to fully perform the services for which he’d been hired.

The Russian news outlet Kommersant reports that all four of those who cooperated were released with probation or correctional labor. Zaitsev received a sentence of 3.5 years in prison, and defendant Alexander Kovalev got four years.

In 2017, KrebsOnSecurity profiled Trump’s Dumps, and found the contact address listed on the site was tied to an email address used to register more than a dozen domains that were made to look like legitimate Javascript calls many e-commerce sites routinely make to process transactions — such as “js-link[dot]su,” “js-stat[dot]su,” and “js-mod[dot]su.”

Searching on those malicious domains revealed a 2016 report from RiskIQ, which shows the domains featured prominently in a series of hacking campaigns against e-commerce websites. According to RiskIQ, the attacks targeted online stores running outdated and unpatched versions of shopping cart software from Magento, Powerfront and OpenCart.

Those shopping cart flaws allowed the crooks to install “web skimmers,” malicious Javascript used to steal credit card details and other information from payment forms on the checkout pages of vulnerable e-commerce sites. The stolen customer payment card details were then sold on sites like Trump’s Dumps and Sky-Fraud.

Who Stole 3.6M Tax Records from South Carolina?

16 April 2024 at 07:26

For nearly a dozen years, residents of South Carolina have been kept in the dark by state and federal investigators over who was responsible for hacking into the state’s revenue department in 2012 and stealing tax and bank account information for 3.6 million people. The answer may no longer be a mystery: KrebsOnSecurity found compelling clues suggesting the intrusion was carried out by the same Russian hacking crew that stole of millions of payment card records from big box retailers like Home Depot and Target in the years that followed.

Questions about who stole tax and financial data on roughly three quarters of all South Carolina residents came to the fore last week at the confirmation hearing of Mark Keel, who was appointed in 2011 by Gov. Nikki Haley to head the state’s law enforcement division. If approved, this would be Keel’s third six-year term in that role.

The Associated Press reports that Keel was careful not to release many details about the breach at his hearing, telling lawmakers he knows who did it but that he wasn’t ready to name anyone.

“I think the fact that we didn’t come up with a whole lot of people’s information that got breached is a testament to the work that people have done on this case,” Keel asserted.

A ten-year retrospective published in 2022 by The Post and Courier in Columbia, S.C. said investigators determined the breach began on Aug. 13, 2012, after a state IT contractor clicked a malicious link in an email. State officials said they found out about the hack from federal law enforcement on October 10, 2012.

KrebsOnSecurity examined posts across dozens of cybercrime forums around that time, and found only one instance of someone selling large volumes of tax data in the year surrounding the breach date.

On Oct. 7, 2012 — three days before South Carolina officials say they first learned of the intrusion — a notorious cybercriminal who goes by the handle “Rescator” advertised the sale of “a database of the tax department of one of the states.”

“Bank account information, SSN and all other information,” Rescator’s sales thread on the Russian-language crime forum Embargo read. “If you purchase the entire database, I will give you access to it.”

A week later, Rescator posted a similar offer on the exclusive Russian forum Mazafaka, saying he was selling information from a U.S. state tax database, without naming the state. Rescator said the data exposed included Social Security Number (SSN), employer, name, address, phone, taxable income, tax refund amount, and bank account number.

“There is a lot of information, I am ready to sell the entire database, with access to the database, and in parts,” Rescator told Mazafaka members. “There is also information on corporate taxpayers.”

On Oct. 26, 2012, the state announced the breach publicly. State officials said they were working with investigators from the U.S. Secret Service and digital forensics experts from Mandiant, which produced an incident report (PDF) that was later published by South Carolina Dept. of Revenue. KrebsOnSecurity sought comment from the Secret Service, South Carolina prosecutors, and Mr. Keel’s office. This story will be updated if any of them respond. Update: The Secret Service declined to comment.

On Nov. 18, 2012, Rescator told fellow denizens of the forum Verified he was selling a database of 65,000 records with bank account information from several smaller, regional financial institutions. Rescator’s sales thread on Verified listed more than a dozen database fields, including account number, name, address, phone, tax ID, date of birth, employer and occupation.

Asked to provide more context about the database for sale, Rescator told forum members the database included financial records related to tax filings of a U.S. state. Rescator added that there was a second database of around 80,000 corporations that included social security numbers, names and addresses, but no financial information.

The AP says South Carolina paid $12 million to Experian for identity theft protection and credit monitoring for its residents after the breach.

“At the time, it was one of the largest breaches in U.S. history but has since been surpassed greatly by hacks to Equifax, Yahoo, Home Depot, Target and PlayStation,” the AP’s Jeffrey Collins wrote.

As it happens, Rescator’s criminal hacking crew was directly responsible for the 2013 breach at Target and the 2014 hack of Home Depot. The Target intrusion saw Rescator’s cybercrime shops selling roughly 40 million stolen payment cards, and 56 million cards from Home Depot customers.

Who is Rescator? On Dec. 14, 2023, KrebsOnSecurity published the results of a 10-year investigation into the identity of Rescator, a.k.a. Mikhail Borisovich Shefel, a 36-year-old who lives in Moscow and who recently changed his last name to Lenin.

Mr. Keel’s assertion that somehow the efforts of South Carolina officials following the breach may have lessened its impact on citizens seems unlikely. The stolen tax and financial data appears to have been sold openly on cybercrime forums by one of the Russian underground’s most aggressive and successful hacking crews.

While there are no indications from reviewing forum posts that Rescator ever sold the data, his sales threads came at a time when the incidence of tax refund fraud was skyrocketing.

Tax-related identity theft occurs when someone uses a stolen identity and SSN to file a tax return in that person’s name claiming a fraudulent refund. Victims usually first learn of the crime after having their returns rejected because scammers beat them to it. Even those who are not required to file a return can be victims of refund fraud, as can those who are not actually owed a refund from the U.S. Internal Revenue Service (IRS).

According to a 2013 report from the Treasury Inspector General’s office, the IRS issued nearly $4 billion in bogus tax refunds in 2012, and more than $5.8 billion in 2013. The money largely was sent to people who stole SSNs and other information on U.S. citizens, and then filed fraudulent tax returns on those individuals claiming a large refund but at a different address.

It remains unclear why Shefel has never been officially implicated in the breaches at Target, Home Depot, or in South Carolina. It may be that Shefel has been indicted, and that those indictments remain sealed for some reason. Perhaps prosecutors were hoping Shefel would decide to leave Russia, at which point it would be easier to apprehend him if he believed no one was looking for him.

But all signs are that Shefel is deeply rooted in Russia, and has no plans to leave. In January 2024, authorities in Australia, the United States and the U.K. levied financial sanctions against 33-year-old Russian man Aleksandr Ermakov for allegedly stealing data on 10 million customers of the Australian health insurance giant Medibank.

A week after those sanctions were put in place, KrebsOnSecurity published a deep dive on Ermakov, which found that he co-ran a Moscow-based IT security consulting business along with Mikhail Shefel called Shtazi-IT.

‘The Manipulaters’ Improve Phishing, Still Fail at Opsec

3 April 2024 at 09:16

Roughly nine years ago, KrebsOnSecurity profiled a Pakistan-based cybercrime group called “The Manipulaters,” a sprawling web hosting network of phishing and spam delivery platforms. In January 2024, The Manipulaters pleaded with this author to unpublish previous stories about their work, claiming the group had turned over a new leaf and gone legitimate. But new research suggests that while they have improved the quality of their products and services, these nitwits still fail spectacularly at hiding their illegal activities.

In May 2015, KrebsOnSecurity published a brief writeup about the brazen Manipulaters team, noting that they openly operated hundreds of web sites selling tools designed to trick people into giving up usernames and passwords, or deploying malicious software on their PCs.

Manipulaters advertisement for “Office 365 Private Page with Antibot” phishing kit sold on the domain heartsender,com. “Antibot” refers to functionality that attempts to evade automated detection techniques, keeping a phish deployed as long as possible. Image: DomainTools.

The core brand of The Manipulaters has long been a shared cybercriminal identity named “Saim Raza,” who for the past decade has peddled a popular spamming and phishing service variously called “Fudtools,” “Fudpage,” “Fudsender,” “FudCo,” etc. The term “FUD” in those names stands for “Fully Un-Detectable,” and it refers to cybercrime resources that will evade detection by security tools like antivirus software or anti-spam appliances.

A September 2021 story here checked in on The Manipulaters, and found that Saim Raza and company were prospering under their FudCo brands, which they secretly managed from a front company called We Code Solutions.

That piece worked backwards from all of the known Saim Raza email addresses to identify Facebook profiles for multiple We Code Solutions employees, many of whom could be seen celebrating company anniversaries gathered around a giant cake with the words “FudCo” painted in icing.

Since that story ran, KrebsOnSecurity has heard from this Saim Raza identity on two occasions. The first was in the weeks following the Sept. 2021 piece, when one of Saim Raza’s known email addresses — bluebtcus@gmail.com — pleaded to have the story taken down.

“Hello, we already leave that fud etc before year,” the Saim Raza identity wrote. “Why you post us? Why you destroy our lifes? We never harm anyone. Please remove it.”

Not wishing to be manipulated by a phishing gang, KrebsOnSecurity ignored those entreaties. But on Jan. 14, 2024, KrebsOnSecurity heard from the same bluebtcus@gmail.com address, apropos of nothing.

“Please remove this article,” Sam Raza wrote, linking to the 2021 profile. “Please already my police register case on me. I already leave everything.”

Asked to elaborate on the police investigation, Saim Raza said they were freshly released from jail.

“I was there many days,” the reply explained. “Now back after bail. Now I want to start my new work.”

Exactly what that “new work” might entail, Saim Raza wouldn’t say. But a new report from researchers at DomainTools.com finds that several computers associated with The Manipulaters have been massively hacked by malicious data- and password-snarfing malware for quite some time.

DomainTools says the malware infections on Manipulaters PCs exposed “vast swaths of account-related data along with an outline of the group’s membership, operations, and position in the broader underground economy.”

“Curiously, the large subset of identified Manipulaters customers appear to be compromised by the same stealer malware,” DomainTools wrote. “All observed customer malware infections began after the initial compromise of Manipulaters PCs, which raises a number of questions regarding the origin of those infections.”

A number of questions, indeed. The core Manipulaters product these days is a spam delivery service called HeartSender, whose homepage openly advertises phishing kits targeting users of various Internet companies, including Microsoft 365, Yahoo, AOL, Intuit, iCloud and ID.me, to name a few.

A screenshot of the homepage of HeartSender 4 displays an IP address tied to fudtoolshop@gmail.com. Image: DomainTools.

HeartSender customers can interact with the subscription service via the website, but the product appears to be far more effective and user-friendly if one downloads HeartSender as a Windows executable program. Whether that HeartSender program was somehow compromised and used to infect the service’s customers is unknown.

However, DomainTools also found the hosted version of HeartSender service leaks an extraordinary amount of user information that probably is not intended to be publicly accessible. Apparently, the HeartSender web interface has several webpages that are accessible to unauthenticated users, exposing customer credentials along with support requests to HeartSender developers.

“Ironically, the Manipulaters may create more short-term risk to their own customers than law enforcement,” DomainTools wrote. “The data table “User Feedbacks” (sic) exposes what appear to be customer authentication tokens, user identifiers, and even a customer support request that exposes root-level SMTP credentials–all visible by an unauthenticated user on a Manipulaters-controlled domain. Given the risk for abuse, this domain will not be published.”

This is hardly the first time The Manipulaters have shot themselves in the foot. In 2019, The Manipulaters failed to renew their core domain name — manipulaters[.]com — the same one tied to so many of the company’s past and current business operations. That domain was quickly scooped up by Scylla Intel, a cyber intelligence firm that focuses on connecting cybercriminals to their real-life identities.

Currently, The Manipulaters seem focused on building out and supporting HeartSender, which specializes in spam and email-to-SMS spamming services.

“The Manipulaters’ newfound interest in email-to-SMS spam could be in response to the massive increase in smishing activity impersonating the USPS,” DomainTools wrote. “Proofs posted on HeartSender’s Telegram channel contain numerous references to postal service impersonation, including proving delivery of USPS-themed phishing lures and the sale of a USPS phishing kit.”

Reached via email, the Saim Raza identity declined to respond to questions about the DomainTools findings.

“First [of] all we never work on virus or compromised computer etc,” Raza replied. “If you want to write like that fake go ahead. Second I leave country already. If someone bind anything with exe file and spread on internet its not my fault.”

Asked why they left Pakistan, Saim Raza said the authorities there just wanted to shake them down.

“After your article our police put FIR on my [identity],” Saim Raza explained. “FIR” in this case stands for “First Information Report,” which is the initial complaint in the criminal justice system of Pakistan.

“They only get money from me nothing else,” Saim Raza continued. “Now some officers ask for money again again. Brother, there is no good law in Pakistan just they need money.”

Saim Raza has a history of being slippery with the truth, so who knows whether The Manipulaters and/or its leaders have in fact fled Pakistan (it may be more of an extended vacation abroad). With any luck, these guys will soon venture into a more Western-friendly, “good law” nation and receive a warm welcome by the local authorities.

Thread Hijacking: Phishes That Prey on Your Curiosity

28 March 2024 at 19:56

Thread hijacking attacks. They happen when someone you know has their email account compromised, and you are suddenly dropped into an existing conversation between the sender and someone else. These missives draw on the recipient’s natural curiosity about being copied on a private discussion, which is modified to include a malicious link or attachment. Here’s the story of a thread hijacking attack in which a journalist was copied on a phishing email from the unwilling subject of a recent scoop.

In Sept. 2023, the Pennsylvania news outlet LancasterOnline.com published a story about Adam Kidan, a wealthy businessman with a criminal past who is a major donor to Republican causes and candidates, including Rep. Lloyd Smucker (R-Pa).

The LancasterOnline story about Adam Kidan.

Several months after that piece ran, the story’s author Brett Sholtis received two emails from Kidan, both of which contained attachments. One of the messages appeared to be a lengthy conversation between Kidan and a colleague, with the subject line, “Re: Successfully sent data.” The second missive was a more brief email from Kidan with the subject, “Acknowledge New Work Order,” and a message that read simply, “Please find the attached.”

Sholtis said he clicked the attachment in one of the messages, which then launched a web page that looked exactly like a Microsoft Office 365 login page. An analysis of the webpage reveals it would check any submitted credentials at the real Microsoft website, and return an error if the user entered bogus account information. A successful login would record the submitted credentials and forward the victim to the real Microsoft website.

But Sholtis said he didn’t enter his Outlook username and password. Instead, he forwarded the messages to LancasterOneline’s IT team, which quickly flagged them as phishing attempts.

LancasterOnline Executive Editor Tom Murse said the two phishing messages from Mr. Kidan raised eyebrows in the newsroom because Kidan had threatened to sue the news outlet multiple times over Sholtis’s story.

“We were just perplexed,” Murse said. “It seemed to be a phishing attempt but we were confused why it would come from a prominent businessman we’ve written about. Our initial response was confusion, but we didn’t know what else to do with it other than to send it to the FBI.”

The phishing lure attached to the thread hijacking email from Mr. Kidan.

In 2006, Kidan was sentenced to 70 months in federal prison after pleading guilty to defrauding lenders along with Jack Abramoff, the disgraced lobbyist whose corruption became a symbol of the excesses of Washington influence peddling. He was paroled in 2009, and in 2014 moved his family to a home in Lancaster County, Pa.

The FBI hasn’t responded to LancasterOnline’s tip. Messages sent by KrebsOnSecurity to Kidan’s emails addresses were returned as blocked. Messages left with Mr. Kidan’s company, Empire Workforce Solutions, went unreturned.

No doubt the FBI saw the messages from Kidan for what they likely were: The result of Mr. Kidan having his Microsoft Outlook account compromised and used to send malicious email to people in his contacts list.

Thread hijacking attacks are hardly new, but that is mainly true because many Internet users still don’t know how to identify them. The email security firm Proofpoint says it has tracked north of 90 million malicious messages in the last five years that leverage this attack method.

One key reason thread hijacking is so successful is that these attacks generally do not include the tell that exposes most phishing scams: A fabricated sense of urgency. A majority of phishing threats warn of negative consequences should you fail to act quickly — such as an account suspension or an unauthorized high-dollar charge going through.

In contrast, thread hijacking campaigns tend to patiently prey on the natural curiosity of the recipient.

Ryan Kalember, chief strategy officer at Proofpoint, said probably the most ubiquitous examples of thread hijacking are “CEO fraud” or “business email compromise” scams, wherein employees are tricked by an email from a senior executive into wiring millions of dollars to fraudsters overseas.

But Kalember said these low-tech attacks can nevertheless be quite effective because they tend to catch people off-guard.

“It works because you feel like you’re suddenly included in an important conversation,” Kalember said. “It just registers a lot differently when people start reading, because you think you’re observing a private conversation between two different people.”

Some thread hijacking attacks actually involve multiple threat actors who are actively conversing while copying — but not addressing — the recipient.

“We call these multi-persona phishing scams, and they’re often paired with thread hijacking,” Kalember said. “It’s basically a way to build a little more affinity than just copying people on an email. And the longer the conversation goes on, the higher their success rate seems to be because some people start replying to the thread [and participating] psycho-socially.”

The best advice to sidestep phishing scams is to avoid clicking on links or attachments that arrive unbidden in emails, text messages and other mediums. If you’re unsure whether the message is legitimate, take a deep breath and visit the site or service in question manually — ideally, using a browser bookmark so as to avoid potential typosquatting sites.

Mozilla Drops Onerep After CEO Admits to Running People-Search Networks

22 March 2024 at 15:02

The nonprofit organization that supports the Firefox web browser said today it is winding down its new partnership with Onerep, an identity protection service recently bundled with Firefox that offers to remove users from hundreds of people-search sites. The move comes just days after a report by KrebsOnSecurity forced Onerep’s CEO to admit that he has founded dozens of people-search networks over the years.

Mozilla Monitor. Image Mozilla Monitor Plus video on Youtube.

Mozilla only began bundling Onerep in Firefox last month, when it announced the reputation service would be offered on a subscription basis as part of Mozilla Monitor Plus. Launched in 2018 under the name Firefox Monitor, Mozilla Monitor also checks data from the website Have I Been Pwned? to let users know when their email addresses or password are leaked in data breaches.

On March 14, KrebsOnSecurity published a story showing that Onerep’s Belarusian CEO and founder Dimitiri Shelest launched dozens of people-search services since 2010, including a still-active data broker called Nuwber that sells background reports on people. Onerep and Shelest did not respond to requests for comment on that story.

But on March 21, Shelest released a lengthy statement wherein he admitted to maintaining an ownership stake in Nuwber, a consumer data broker he founded in 2015 — around the same time he launched Onerep.

Shelest maintained that Nuwber has “zero cross-over or information-sharing with Onerep,” and said any other old domains that may be found and associated with his name are no longer being operated by him.

“I get it,” Shelest wrote. “My affiliation with a people search business may look odd from the outside. In truth, if I hadn’t taken that initial path with a deep dive into how people search sites work, Onerep wouldn’t have the best tech and team in the space. Still, I now appreciate that we did not make this more clear in the past and I’m aiming to do better in the future.” The full statement is available here (PDF).

Onerep CEO and founder Dimitri Shelest.

In a statement released today, a spokesperson for Mozilla said it was moving away from Onerep as a service provider in its Monitor Plus product.

“Though customer data was never at risk, the outside financial interests and activities of Onerep’s CEO do not align with our values,” Mozilla wrote. “We’re working now to solidify a transition plan that will provide customers with a seamless experience and will continue to put their interests first.”

KrebsOnSecurity also reported that Shelest’s email address was used circa 2010 by an affiliate of Spamit, a Russian-language organization that paid people to aggressively promote websites hawking male enhancement drugs and generic pharmaceuticals. As noted in the March 14 story, this connection was confirmed by research from multiple graduate students at my alma mater George Mason University.

Shelest denied ever being associated with Spamit. “Between 2010 and 2014, we put up some web pages and optimize them — a widely used SEO practice — and then ran AdSense banners on them,” Shelest said, presumably referring to the dozens of people-search domains KrebsOnSecurity found were connected to his email addresses (dmitrcox@gmail.com and dmitrcox2@gmail.com). “As we progressed and learned more, we saw that a lot of the inquiries coming in were for people.”

Shelest also acknowledged that Onerep pays to run ads on “on a handful of data broker sites in very specific circumstances.”

“Our ad is served once someone has manually completed an opt-out form on their own,” Shelest wrote. “The goal is to let them know that if they were exposed on that site, there may be others, and bring awareness to there being a more automated opt-out option, such as Onerep.”

Reached via Twitter/X, HaveIBeenPwned founder Troy Hunt said he knew Mozilla was considering a partnership with Onerep, but that he was previously unaware of the Onerep CEO’s many conflicts of interest.

“I knew Mozilla had this in the works and we’d casually discussed it when talking about Firefox monitor,” Hunt told KrebsOnSecurity. “The point I made to them was the same as I’ve made to various companies wanting to put data broker removal ads on HIBP: removing your data from legally operating services has minimal impact, and you can’t remove it from the outright illegal ones who are doing the genuine damage.”

Playing both sides — creating and spreading the same digital disease that your medicine is designed to treat — may be highly unethical and wrong. But in the United States it’s not against the law. Nor is collecting and selling data on Americans. Privacy experts say the problem is that data brokers, people-search services like Nuwber and Onerep, and online reputation management firms exist because virtually all U.S. states exempt so-called “public” or “government” records from consumer privacy laws.

Those include voting registries, property filings, marriage certificates, motor vehicle records, criminal records, court documents, death records, professional licenses, and bankruptcy filings. Data brokers also can enrich consumer records with additional information, by adding social media data and known associates.

The March 14 story on Onerep was the second in a series of three investigative reports published here this month that examined the data broker and people-search industries, and highlighted the need for more congressional oversight — if not regulation — on consumer data protection and privacy.

On March 8, KrebsOnSecurity published A Close Up Look at the Consumer Data Broker Radaris, which showed that the co-founders of Radaris operate multiple Russian-language dating services and affiliate programs. It also appears many of their businesses have ties to a California marketing firm that works with a Russian state-run media conglomerate currently sanctioned by the U.S. government.

On March 20, KrebsOnSecurity published The Not-So-True People-Search Network from China, which revealed an elaborate web of phony people-search companies and executives designed to conceal the location of people-search affiliates in China who are earning money promoting U.S. based data brokers that sell personal information on Americans.

Incognito Darknet Market Mass-Extorts Buyers, Sellers

11 March 2024 at 12:19

Borrowing from the playbook of ransomware purveyors, the darknet narcotics bazaar Incognito Market has begun extorting all of its vendors and buyers, threatening to publish cryptocurrency transaction and chat records of users who refuse to pay a fee ranging from $100 to $20,000. The bold mass extortion attempt comes just days after Incognito Market administrators reportedly pulled an “exit scam” that left users unable to withdraw millions of dollars worth of funds from the platform.

An extortion message currently on the Incognito Market homepage.

In the past 24 hours, the homepage for the Incognito Market was updated to include a blackmail message from its owners, saying they will soon release purchase records of vendors who refuse to pay to keep the records confidential.

“We got one final little nasty surprise for y’all,” reads the message to Incognito Market users. “We have accumulated a list of private messages, transaction info and order details over the years. You’ll be surprised at the number of people that relied on our ‘auto-encrypt’ functionality. And by the way, your messages and transaction IDs were never actually deleted after the ‘expiry’….SURPRISE SURPRISE!!! Anyway, if anything were to leak to law enforcement, I guess nobody never slipped up.”

Incognito Market says it plans to publish the entire dump of 557,000 orders and 862,000 cryptocurrency transaction IDs at the end of May.

“Whether or not you and your customers’ info is on that list is totally up to you,” the Incognito administrators advised. “And yes, this is an extortion!!!!”

The extortion message includes a “Payment Status” page that lists the darknet market’s top vendors by their handles, saying at the top that “you can see which vendors care about their customers below.” The names in green supposedly correspond to users who have already opted to pay.

The “Payment Status” page set up by the Incognito Market extortionists.

We’ll be publishing the entire dump of 557k orders and 862k crypto transaction IDs at the end of May, whether or not you and your customers’ info is on that list is totally up to you. And yes, this is an extortion!!!!

Incognito Market said it plans to open up a “whitelist portal” for buyers to remove their transaction records “in a few weeks.”

The mass-extortion of Incognito Market users comes just days after a large number of users reported they were no longer able to withdraw funds from their buyer or seller accounts. The cryptocurrency-focused publication Cointelegraph.com reported Mar. 6 that Incognito was exit-scamming its users out of their bitcoins and Monero deposits.

CoinTelegraph notes that Incognito Market administrators initially lied about the situation, and blamed users’ difficulties in withdrawing funds on recent changes to Incognito’s withdrawal systems.

Incognito Market deals primarily in narcotics, so it’s likely many users are now worried about being outed as drug dealers. Creating a new account on Incognito Market presents one with an ad for 5 grams of heroin selling for $450.

New Incognito Market users are treated to an ad for $450 worth of heroin.

The double whammy now hitting Incognito Market users is somewhat akin to the double extortion techniques employed by many modern ransomware groups, wherein victim organizations are hacked, relieved of sensitive information and then presented with two separate ransom demands: One in exchange for a digital key needed to unlock infected systems, and another to secure a promise that any stolen data will not be published or sold, and will be destroyed.

Incognito Market has priced its extortion for vendors based on their status or “level” within the marketplace. Level 1 vendors can supposedly have their information removed by paying a $100 fee. However, larger “Level 5” vendors are asked to cough up $20,000 payments.

The past is replete with examples of similar darknet market exit scams, which tend to happen eventually to all darknet markets that aren’t seized and shut down by federal investigators, said Brett Johnson, a convicted and reformed cybercriminal who built the organized cybercrime community Shadowcrew many years ago.

“Shadowcrew was the precursor to today’s Darknet Markets and laid the foundation for the way modern cybercrime channels still operate today,” Johnson said. “The Truth of Darknet Markets? ALL of them are Exit Scams. The only question is whether law enforcement can shut down the market and arrest its operators before the exit scam takes place.”

FBI’s LockBit Takedown Postponed a Ticking Time Bomb in Fulton County, Ga.

25 February 2024 at 21:17

The FBI’s takedown of the LockBit ransomware group last week came as LockBit was preparing to release sensitive data stolen from government computer systems in Fulton County, Ga. But LockBit is now regrouping, and the gang says it will publish the stolen Fulton County data on March 2 unless paid a ransom. LockBit claims the cache includes documents tied to the county’s ongoing criminal prosecution of former President Trump, but court watchers say teaser documents published by the crime gang suggest a total leak of the Fulton County data could put lives at risk and jeopardize a number of other criminal trials.

A new LockBit website listing a countdown timer until the promised release of data stolen from Fulton County, Ga.

In early February, Fulton County leaders acknowledged they were responding to an intrusion that caused disruptions for its phone, email and billing systems, as well as a range of county services, including court systems.

On Feb. 13, the LockBit ransomware group posted on its victim shaming blog a new entry for Fulton County, featuring a countdown timer saying the group would publish the data on Feb. 16 unless county leaders agreed to negotiate a ransom.

“We will demonstrate how local structures negligently handled information protection,” LockBit warned. “We will reveal lists of individuals responsible for confidentiality. Documents marked as confidential will be made publicly available. We will show documents related to access to the state citizens’ personal data. We aim to give maximum publicity to this situation; the documents will be of interest to many. Conscientious residents will bring order.”

Yet on Feb. 16, the entry for Fulton County was removed from LockBit’s site without explanation. This usually only happens after the victim in question agrees to pay a ransom demand and/or enters into negotiations with their extortionists.

However, Fulton County Commission Chairman Robb Pitts said the board decided it “could not in good conscience use Fulton County taxpayer funds to make a payment.”

“We did not pay nor did anyone pay on our behalf,” Pitts said at an incident briefing on Feb. 20.

Just hours before that press conference, LockBit’s various websites were seized by the FBI and the U.K.’s National Crime Agency (NCA), which replaced the ransomware group’s homepage with a seizure notice and used the existing design of LockBit’s victim shaming blog to publish press releases about the law enforcement action.

The feds used the existing design on LockBit’s victim shaming website to feature press releases and free decryption tools.

Dubbed “Operation Cronos,” the effort involved the seizure of nearly three-dozen servers; the arrest of two alleged LockBit members; the release of a free LockBit decryption tool; and the freezing of more than 200 cryptocurrency accounts thought to be tied to the gang’s activities. The government says LockBit has claimed more than 2,000 victims worldwide and extorted over $120 million in payments.

UNFOLDING DISASTER

In a lengthy, rambling letter published on Feb. 24 and addressed to the FBI, the ransomware group’s leader LockBitSupp announced that their victim shaming websites were once again operational on the dark web, with fresh countdown timers for Fulton County and a half-dozen other recent victims.

“The FBI decided to hack now for one reason only, because they didn’t want to leak information fultoncountyga.gov,” LockBitSupp wrote. “The stolen documents contain a lot of interesting things and Donald Trump’s court cases that could affect the upcoming US election.”

A screen shot released by LockBit showing various Fulton County file shares that were exposed.

LockBit has already released roughly two dozen files allegedly stolen from Fulton County government systems, although none of them involve Mr. Trump’s criminal trial. But the documents do appear to include court records that are sealed and shielded from public viewing.

George Chidi writes The Atlanta Objective, a Substack publication on crime in Georgia’s capital city. Chidi says the leaked data so far includes a sealed record related to a child abuse case, and a sealed motion in the murder trial of Juwuan Gaston demanding the state turn over confidential informant identities.

Chidi cites reports from a Fulton County employee who said the confidential material includes the identities of jurors serving on the trial of the rapper Jeffery “Young Thug” Williams, who is charged along with five other defendants in a racketeering and gang conspiracy.

“The screenshots suggest that hackers will be able to give any attorney defending a criminal case in the county a starting place to argue that evidence has been tainted or witnesses intimidated, and that the release of confidential information has compromised cases,” Chidi wrote. “Judge Ural Glanville has, I am told by staff, been working feverishly behind the scenes over the last two weeks to manage the unfolding disaster.”

LockBitSupp also denied assertions made by the U.K.’s NCA that LockBit did not delete stolen data as promised when victims agreed to pay a ransom. The accusation is an explosive one because nobody will pay a ransom if they don’t believe the ransomware group will hold up its end of the bargain.

The ransomware group leader also confirmed information first reported here last week, that federal investigators managed to hack LockBit by exploiting a known vulnerability in PHP, a scripting language that is widely used in Web development.

“Due to my personal negligence and irresponsibility I relaxed and did not update PHP in time,” LockBitSupp wrote. “As a result of which access was gained to the two main servers where this version of PHP was installed.”

LockBitSupp’s FBI letter said the group kept copies of its stolen victim data on servers that did not use PHP, and that consequently it was able to retain copies of files stolen from victims. The letter also listed links to multiple new instances of LockBit dark net websites, including the leak page listing Fulton County’s new countdown timer.

LockBit’s new data leak site promises to release stolen Fulton County data on March 2, 2024, unless paid a ransom demand.

“Even after the FBI hack, the stolen data will be published on the blog, there is no chance of destroying the stolen data without payment,” LockBitSupp wrote. “All FBI actions are aimed at destroying the reputation of my affiliate program, my demoralization, they want me to leave and quit my job, they want to scare me because they can not find and eliminate me, I can not be stopped, you can not even hope, as long as I am alive I will continue to do pentest with postpaid.”

DOX DODGING

In January 2024, LockBitSupp told XSS forum members he was disappointed the FBI hadn’t offered a reward for his doxing and/or arrest, and that in response he was placing a bounty on his own head — offering $10 million to anyone who could discover his real name.

After the NCA and FBI seized LockBit’s site, the group’s homepage was retrofitted with a blog entry titled, “Who is LockBitSupp? The $10M question.” The teaser made use of LockBit’s own countdown timer, and suggested the real identity of LockBitSupp would soon be revealed.

However, after the countdown timer expired the page was replaced with a taunting message from the feds, but it included no new information about LockBitSupp’s identity.

On Feb. 21, the U.S. Department of State announced rewards totaling up to $15 million for information leading to the arrest and/or conviction of anyone participating in LockBit ransomware attacks. The State Department said $10 million of that is for information on LockBit’s leaders, and up to $5 million is offered for information on affiliates.

In an interview with the malware-focused Twitter/X account Vx-Underground, LockBit staff asserted that authorities had arrested a couple of small-time players in their operation, and that investigators still do not know the real-life identities of the core LockBit members, or that of their leader.

“They assert the FBI / NCA UK / EUROPOL do not know their information,” Vx-Underground wrote. “They state they are willing to double the bounty of $10,000,000. They state they will place a $20,000,000 bounty of their own head if anyone can dox them.”

TROUBLE ON THE HOMEFRONT?

In the weeks leading up to the FBI/NCA takedown, LockBitSupp became embroiled in a number of high-profile personal and business disputes on the Russian cybercrime forums.

Earlier this year, someone used LockBit ransomware to infect the networks of AN-Security, a venerated 30-year-old security and technology company based in St. Petersburg, Russia. This violated the golden rule for cybercriminals based in Russia and former soviet nations that make up the Commonwealth of Independent States, which is that attacking your own citizens in those countries is the surest way to get arrested and prosecuted by local authorities.

LockBitSupp later claimed the attacker had used a publicly leaked, older version of LockBit to compromise systems at AN-Security, and said the attack was an attempt to smear their reputation by a rival ransomware group known as “Clop.” But the incident no doubt prompted closer inspection of LockBitSupp’s activities by Russian authorities.

Then in early February, the administrator of the Russian-language cybercrime forum XSS said LockBitSupp had threatened to have him killed after the ransomware group leader was banned by the community. LockBitSupp was excommunicated from XSS after he refused to pay an arbitration amount ordered by the forum administrator. That dispute related to a complaint from another forum member who said LockBitSupp recently stiffed him on his promised share of an unusually large ransomware payout.

A posted by the XSS administrator saying LockBitSupp wanted him dead.

INTERVIEW WITH LOCKBITSUPP

KrebsOnSecurity sought comment from LockBitSupp at the ToX instant messenger ID listed in his letter to the FBI. LockBitSupp declined to elaborate on the unreleased documents from Fulton County, saying the files will be available for everyone to see in a few days.

LockBitSupp said his team was still negotiating with Fulton County when the FBI seized their servers, which is why the county has been granted a time extension. He also denied threatening to kill the XSS administrator.

“I have not threatened to kill the XSS administrator, he is blatantly lying, this is to cause self-pity and damage my reputation,” LockBitSupp told KrebsOnSecurity. “It is not necessary to kill him to punish him, there are more humane methods and he knows what they are.”

Asked why he was so certain the FBI doesn’t know his real-life identity, LockBitSupp was more precise.

“I’m not sure the FBI doesn’t know who I am,” he said. “I just believe they will never find me.”

It seems unlikely that the FBI’s seizure of LockBit’s infrastructure was somehow an effort to stave off the disclosure of Fulton County’s data, as LockBitSupp maintains. For one thing, Europol said the takedown was the result of a months-long infiltration of the ransomware group.

Also, in reporting on the attack’s disruption to the office of Fulton County District Attorney Fani Willis on Feb. 14, CNN reported that by then the intrusion by LockBit had persisted for nearly two and a half weeks.

Finally, if the NCA and FBI really believed that LockBit never deleted victim data, they had to assume LockBit would still have at least one copy of all their stolen data hidden somewhere safe.

Fulton County is still trying to recover systems and restore services affected by the ransomware attack. “Fulton County continues to make substantial progress in restoring its systems following the recent ransomware incident resulting in service outages,” reads the latest statement from the county on Feb. 22. “Since the start of this incident, our team has been working tirelessly to bring services back up.”

Update, Feb. 29, 3:22 p.m. ET: Just hours after this story ran, LockBit changed its countdown timer for Fulton County saying they had until the morning of Feb. 29 (today) to pay a ransonm demand. When the official deadline neared today, Fulton County’s listing was removed from LockBit’s victim shaming website. Asked about the removal of the listing, LockBit’s leader “LockBitSupp” told KrebsOnSecurity that Fulton County paid a ransom demand. County officials have scheduled a press conference on the ransomware attack at 4:15 p.m. ET today.

New Leak Shows Business Side of China’s APT Menace

22 February 2024 at 08:27

A new data leak that appears to have come from one of China’s top private cybersecurity firms provides a rare glimpse into the commercial side of China’s many state-sponsored hacking groups. Experts say the leak illustrates how Chinese government agencies increasingly are contracting out foreign espionage campaigns to the nation’s burgeoning and highly competitive cybersecurity industry.

A marketing slide deck promoting i-SOON’s Advanced Persistent Threat (APT) capabilities.

A large cache of more than 500 documents published to GitHub last week indicate the records come from i-SOON, a technology company headquartered in Shanghai that is perhaps best known for providing cybersecurity training courses throughout China. But the leaked documents, which include candid employee chat conversations and images, show a less public side of i-SOON, one that frequently initiates and sustains cyberespionage campaigns commissioned by various Chinese government agencies.

The leaked documents suggest i-SOON employees were responsible for a raft of cyber intrusions over many years, infiltrating government systems in the United Kingdom and countries throughout Asia. Although the cache does not include raw data stolen from cyber espionage targets, it features numerous documents listing the level of access gained and the types of data exposed in each intrusion.

Security experts who reviewed the leaked data say they believe the information is legitimate, and that i-SOON works closely with China’s Ministry of Public Security and the military. In 2021, the Sichuan provincial government named i-SOON as one of “the top 30 information security companies.”

“The leak provides some of the most concrete details seen publicly to date, revealing the maturing nature of China’s cyber espionage ecosystem,” said Dakota Cary, a China-focused consultant at the security firm SentinelOne. “It shows explicitly how government targeting requirements drive a competitive marketplace of independent contractor hackers-for-hire.”

Mei Danowski is a former intelligence analyst and China expert who now writes about her research in a Substack publication called Natto Thoughts. Danowski said i-SOON has achieved the highest secrecy classification that a non-state-owned company can receive, which qualifies the company to conduct classified research and development related to state security.

i-SOON’s “business services” webpage states that the company’s offerings include public security, anti-fraud, blockchain forensics, enterprise security solutions, and training. Danowski said that in 2013, i-SOON established a department for research on developing new APT network penetration methods.

APT stands for Advanced Persistent Threat, a term that generally refers to state-sponsored hacking groups. Indeed, among the documents apparently leaked from i-SOON is a sales pitch slide boldly highlighting the hacking prowess of the company’s “APT research team” (see screenshot above).

The leaked documents included a lengthy chat conversation between the company’s founders, who repeatedly discuss flagging sales and the need to secure more employees and government contracts. Danowski said the CEO of i-SOON, Wu Haibo (“Shutdown” in the leaked chats) is a well-known first-generation red hacker or “Honker,” and an early member of Green Army — the very first Chinese hacktivist group founded in 1997. Mr. Haibo has not yet responded to a request for comment.

In October 2023, Danowski detailed how i-SOON became embroiled in a software development contract dispute when it was sued by a competing Chinese cybersecurity company called Chengdu 404. In September 2020, the U.S. Department of Justice unsealed indictments against multiple Chengdu 404 employees, charging that the company was a facade that hid more than a decade’s worth of cyber intrusions attributed to a threat actor group known as “APT 41.”

Danowski said the existence of this legal dispute suggests that Chengdu 404 and i-SOON have or at one time had a business relationship, and that one company likely served as a subcontractor to the other.

“From what they chat about we can see this is a very competitive industry, where companies in this space are constantly poaching each others’ employees and tools,” Danowski said. “The infosec industry is always trying to distinguish [the work] of one APT group from another. But that’s getting harder to do.”

It remains unclear if i-SOON’s work has earned it a unique APT designation. But Will Thomas, a cyber threat intelligence researcher at Equinix, found an Internet address in the leaked data that corresponds to a domain flagged in a 2019 Citizen Lab report about one-click mobile phone exploits that were being used to target groups in Tibet. The 2019 report referred to the threat actor behind those attacks as an APT group called Poison Carp.

Several images and chat records in the data leak suggest i-SOON’s clients periodically gave the company a list of targets they wanted to infiltrate, but sometimes employees confused the instructions. One screenshot shows a conversation in which an employee tells his boss they’ve just hacked one of the universities on their latest list, only to be told that the victim in question was not actually listed as a desired target.

The leaked chats show i-SOON continuously tried to recruit new talent by hosting a series of hacking competitions across China. It also performed charity work, and sought to engage employees and sustain morale with various team-building events.

However, the chats include multiple conversations between employees commiserating over long hours and low pay. The overall tone of the discussions indicates employee morale was quite low and that the workplace environment was fairly toxic. In several of the conversations, i-SOON employees openly discuss with their bosses how much money they just lost gambling online with their mobile phones while at work.

Danowski believes the i-SOON data was probably leaked by one of those disgruntled employees.

“This was released the first working day after the Chinese New Year,” Danowski said. “Definitely whoever did this planned it, because you can’t get all this information all at once.”

SentinelOne’s Cary said he came to the same conclusion, noting that the Protonmail account tied to the GitHub profile that published the records was registered a month before the leak, on January 15, 2024.

China’s much vaunted Great Firewall not only lets the government control and limit what citizens can access online, but this distributed spying apparatus allows authorities to block data on Chinese citizens and companies from ever leaving the country.

As a result, China enjoys a remarkable information asymmetry vis-a-vis virtually all other industrialized nations. Which is why this apparent data leak from i-SOON is such a rare find for Western security researchers.

“I was so excited to see this,” Cary said. “Every day I hope for data leaks coming out of China.”

That information asymmetry is at the heart of the Chinese government’s cyberwarfare goals, according to a 2023 analysis by Margin Research performed on behalf of the Defense Advanced Research Projects Agency (DARPA).

“In the area of cyberwarfare, the western governments see cyberspace as a ‘fifth domain’ of warfare,” the Margin study observed. “The Chinese, however, look at cyberspace in the broader context of information space. The ultimate objective is, not ‘control’ of cyberspace, but control of information, a vision that dominates China’s cyber operations.”

The National Cybersecurity Strategy issued by the White House last year singles out China as the biggest cyber threat to U.S. interests. While the United States government does contract certain aspects of its cyber operations to companies in the private sector, it does not follow China’s example in promoting the wholesale theft of state and corporate secrets for the commercial benefit of its own private industries.

Dave Aitel, a co-author of the Margin Research report and former computer scientist at the U.S. National Security Agency, said it’s nice to see that Chinese cybersecurity firms have to deal with all of the same contracting headaches facing U.S. companies seeking work with the federal government.

“This leak just shows there’s layers of contractors all the way down,” Aitel said. “It’s pretty fun to see the Chinese version of it.”

Feds Seize LockBit Ransomware Websites, Offer Decryption Tools, Troll Affiliates

20 February 2024 at 12:09

U.S. and U.K. authorities have seized the darknet websites run by LockBit, a prolific and destructive ransomware group that has claimed more than 2,000 victims worldwide and extorted over $120 million in payments. Instead of listing data stolen from ransomware victims who didn’t pay, LockBit’s victim shaming website now offers free recovery tools, as well as news about arrests and criminal charges involving LockBit affiliates.

Investigators used the existing design on LockBit’s victim shaming website to feature press releases and free decryption tools.

Dubbed “Operation Cronos,” the law enforcement action involved the seizure of nearly three-dozen servers; the arrest of two alleged LockBit members; the unsealing of two indictments; the release of a free LockBit decryption tool; and the freezing of more than 200 cryptocurrency accounts thought to be tied to the gang’s activities.

LockBit members have executed attacks against thousands of victims in the United States and around the world, according to the U.S. Department of Justice (DOJ). First surfacing in September 2019, the gang is estimated to have made hundreds of millions of U.S. dollars in ransom demands, and extorted over $120 million in ransom payments.

LockBit operated as a ransomware-as-a-service group, wherein the ransomware gang takes care of everything from the bulletproof hosting and domains to the development and maintenance of the malware. Meanwhile, affiliates are solely responsible for finding new victims, and can reap 60 to 80 percent of any ransom amount ultimately paid to the group.

A statement on Operation Cronos from the European police agency Europol said the months-long infiltration resulted in the compromise of LockBit’s primary platform and other critical infrastructure, including the takedown of 34 servers in the Netherlands, Germany, Finland, France, Switzerland, Australia, the United States and the United Kingdom. Europol said two suspected LockBit actors were arrested in Poland and Ukraine, but no further information has been released about those detained.

The DOJ today unsealed indictments against two Russian men alleged to be active members of LockBit. The government says Russian national Artur Sungatov used LockBit ransomware against victims in manufacturing, logistics, insurance and other companies throughout the United States.

Ivan Gennadievich Kondratyev, a.k.a. “Bassterlord,” allegedly deployed LockBit against targets in the United States, Singapore, Taiwan, and Lebanon. Kondratyev is also charged (PDF) with three criminal counts arising from his alleged use of the Sodinokibi (aka “REvil“) ransomware variant to encrypt data, exfiltrate victim information, and extort a ransom payment from a corporate victim based in Alameda County, California.

With the indictments of Sungatov and Kondratyev, a total of five LockBit affiliates now have been officially charged. In May 2023, U.S. authorities unsealed indictments against two alleged LockBit affiliates, Mikhail “Wazawaka” Matveev and Mikhail Vasiliev.

Vasiliev, 35, of Bradford, Ontario, Canada, is in custody in Canada awaiting extradition to the United States (the complaint against Vasiliev is at this PDF). Matveev remains at large, presumably still in Russia. In January 2022, KrebsOnSecurity published Who is the Network Access Broker ‘Wazawaka,’ which followed clues from Wazawaka’s many pseudonyms and contact details on the Russian-language cybercrime forums back to a 31-year-old Mikhail Matveev from Abaza, RU.

An FBI wanted poster for Matveev.

In June 2023, Russian national Ruslan Magomedovich Astamirov was charged in New Jersey for his participation in the LockBit conspiracy, including the deployment of LockBit against victims in Florida, Japan, France, and Kenya. Astamirov is currently in custody in the United States awaiting trial.

LockBit was known to have recruited affiliates that worked with multiple ransomware groups simultaneously, and it’s unclear what impact this takedown may have on competing ransomware affiliate operations. The security firm ProDaft said on Twitter/X that the infiltration of LockBit by investigators provided “in-depth visibility into each affiliate’s structures, including ties with other notorious groups such as FIN7, Wizard Spider, and EvilCorp.”

In a lengthy thread about the LockBit takedown on the Russian-language cybercrime forum XSS, one of the gang’s leaders said the FBI and the U.K.’s National Crime Agency (NCA) had infiltrated its servers using a known vulnerability in PHP, a scripting language that is widely used in Web development.

Several denizens of XSS wondered aloud why the PHP flaw was not flagged by LockBit’s vaunted “Bug Bounty” program, which promised a financial reward to affiliates who could find and quietly report any security vulnerabilities threatening to undermine LockBit’s online infrastructure.

This prompted several XSS members to start posting memes taunting the group about the security failure.

“Does it mean that the FBI provided a pentesting service to the affiliate program?,” one denizen quipped. “Or did they decide to take part in the bug bounty program? :):)”

Federal investigators also appear to be trolling LockBit members with their seizure notices. LockBit’s data leak site previously featured a countdown timer for each victim organization listed, indicating the time remaining for the victim to pay a ransom demand before their stolen files would be published online. Now, the top entry on the shaming site is a countdown timer until the public doxing of “LockBitSupp,” the unofficial spokesperson or figurehead for the LockBit gang.

“Who is LockbitSupp?” the teaser reads. “The $10m question.”

In January 2024, LockBitSupp told XSS forum members he was disappointed the FBI hadn’t offered a reward for his doxing and/or arrest, and that in response he was placing a bounty on his own head — offering $10 million to anyone who could discover his real name.

“My god, who needs me?,” LockBitSupp wrote on Jan. 22, 2024. “There is not even a reward out for me on the FBI website. By the way, I want to use this chance to increase the reward amount for a person who can tell me my full name from USD 1 million to USD 10 million. The person who will find out my name, tell it to me and explain how they were able to find it out will get USD 10 million. Please take note that when looking for criminals, the FBI uses unclear wording offering a reward of UP TO USD 10 million; this means that the FBI can pay you USD 100, because technically, it’s an amount UP TO 10 million. On the other hand, I am willing to pay USD 10 million, no more and no less.”

Mark Stockley, cybersecurity evangelist at the security firm Malwarebytes, said the NCA is obviously trolling the LockBit group and LockBitSupp.

“I don’t think this is an accident—this is how ransomware groups talk to each other,” Stockley said. “This is law enforcement taking the time to enjoy its moment, and humiliate LockBit in its own vernacular, presumably so it loses face.”

In a press conference today, the FBI said Operation Cronos included investigative assistance from the Gendarmerie-C3N in France; the State Criminal Police Office L-K-A and Federal Criminal Police Office in Germany; Fedpol and Zurich Cantonal Police in Switzerland; the National Police Agency in Japan; the Australian Federal Police; the Swedish Police Authority; the National Bureau of Investigation in Finland; the Royal Canadian Mounted Police; and the National Police in the Netherlands.

The Justice Department said victims targeted by LockBit should contact the FBI at https://lockbitvictims.ic3.gov/ to determine whether affected systems can be successfully decrypted. In addition, the Japanese Police, supported by Europol, have released a recovery tool designed to recover files encrypted by the LockBit 3.0 Black Ransomware.

From Cybercrime Saul Goodman to the Russian GRU

7 February 2024 at 12:10

In 2021, the exclusive Russian cybercrime forum Mazafaka was hacked. The leaked user database shows one of the forum’s founders was an attorney who advised Russia’s top hackers on the legal risks of their work, and what to do if they got caught. A review of this user’s hacker identities shows that during his time on the forums he served as an officer in the special forces of the GRU, the foreign military intelligence agency of the Russian Federation.

Launched in 2001 under the tagline “Network terrorism,” Mazafaka would evolve into one of the most guarded Russian-language cybercrime communities. The forum’s member roster included a Who’s Who of top Russian cybercriminals, and it featured sub-forums for a wide range of cybercrime specialities, including malware, spam, coding and identity theft.

One representation of the leaked Mazafaka database.

In almost any database leak, the first accounts listed are usually the administrators and early core members. But the Mazafaka user information posted online was not a database file per se, and it was clearly edited, redacted and restructured by whoever released it. As a result, it can be difficult to tell which members are the earliest users.

The original Mazafaka is known to have been launched by a hacker using the nickname “Stalker.” However, the lowest numbered (non-admin) user ID in the Mazafaka database belongs to another individual who used the handle “Djamix,” and the email address djamix@mazafaka[.]ru.

From the forum’s inception until around 2008, Djamix was one of its most active and eloquent contributors. Djamix told forum members he was a lawyer, and nearly all of his posts included legal analyses of various public cases involving hackers arrested and charged with cybercrimes in Russia and abroad.

“Hiding with purely technical parameters will not help in a serious matter,” Djamix advised Maza members in September 2007. “In order to ESCAPE the law, you need to KNOW the law. This is the most important thing. Technical capabilities cannot overcome intelligence and cunning.”

Stalker himself credited Djamix with keeping Mazafaka online for so many years. In a retrospective post published to Livejournal in 2014 titled, “Mazafaka, from conception to the present day,” Stalker said Djamix had become a core member of the community.

“This guy is everywhere,” Stalker said of Djamix. “There’s not a thing on [Mazafaka] that he doesn’t take part in. For me, he is a stimulus-irritant and thanks to him, Maza is still alive. Our rallying force!”

Djamix told other forum denizens he was a licensed attorney who could be hired for remote or in-person consultations, and his posts on Mazafaka and other Russian boards show several hackers facing legal jeopardy likely took him up on this offer.

“I have the right to represent your interests in court,” Djamix said on the Russian-language cybercrime forum Verified in Jan. 2011. “Remotely (in the form of constant support and consultations), or in person – this is discussed separately. As well as the cost of my services.”

WHO IS DJAMIX?

A search on djamix@mazafaka[.]ru at DomainTools.com reveals this address has been used to register at least 10 domain names since 2008. Those include several websites about life in and around Sochi, Russia, the site of the 2014 Winter Olympics, as well as a nearby coastal town called Adler. All of those sites say they were registered to an Aleksei Safronov from Sochi who also lists Adler as a hometown.

The breach tracking service Constella Intelligence finds that the phone number associated with those domains — +7.9676442212 — is tied to a Facebook account for an Aleksei Valerievich Safronov from Sochi. Mr. Safronov’s Facebook profile, which was last updated in October 2022, says his ICQ instant messenger number is 53765. This is the same ICQ number assigned to Djamix in the Mazafaka user database.

The Facebook account for Aleksey Safronov.

A “Djamix” account on the forum privetsochi[.]ru (“Hello Sochi”) says this user was born Oct. 2, 1970, and that his website is uposter[.]ru. This Russian language news site’s tagline is, “We Create Communication,” and it focuses heavily on news about Sochi, Adler, Russia and the war in Ukraine, with a strong pro-Kremlin bent.

Safronov’s Facebook profile also gives his Skype username as “Djamixadler,” and it includes dozens of photos of him dressed in military fatigues along with a regiment of soldiers deploying in fairly remote areas of Russia. Some of those photos date back to 2008.

In several of the images, we can see a patch on the arm of Safronov’s jacket that bears the logo of the Spetsnaz GRU, a special forces unit of the Russian military. According to a 2020 report from the Congressional Research Service, the GRU operates both as an intelligence agency — collecting human, cyber, and signals intelligence — and as a military organization responsible for battlefield reconnaissance and the operation of Russia’s Spetsnaz military commando units.

Mr. Safronov posted this image of himself on Facebook in 2016. The insignia of the GRU can be seen on his sleeve.

“In recent years, reports have linked the GRU to some of Russia’s most aggressive and public intelligence operations,” the CRS report explains. “Reportedly, the GRU played a key role in Russia’s occupation of Ukraine’s Crimea region and invasion of eastern Ukraine, the attempted assassination of former Russian intelligence officer Sergei Skripal in the United Kingdom, interference in the 2016 U.S. presidential elections, disinformation and propaganda operations, and some of the world’s most damaging cyberattacks.”

According to the Russia-focused investigative news outlet Meduza, in 2014 the Russian Defense Ministry created its “information-operation troops” for action in “cyber-confrontations with potential adversaries.”

“Later, sources in the Defense Ministry explained that these new troops were meant to ‘disrupt the potential adversary’s information networks,'” Meduza reported in 2018. “Recruiters reportedly went looking for ‘hackers who have had problems with the law.'”

Mr. Safronov did not respond to multiple requests for comment. A 2018 treatise written by Aleksei Valerievich Safronov titled “One Hundred Years of GRU Military Intelligence” explains the significance of the bat in the seal of the GRU.

“One way or another, the bat is an emblem that unites all active and retired intelligence officers; it is a symbol of unity and exclusivity,” Safronov wrote. “And, in general, it doesn’t matter who we’re talking about – a secret GRU agent somewhere in the army or a sniper in any of the special forces brigades. They all did and are doing one very important and responsible thing.”

It’s unclear what role Mr. Safronov plays or played in the GRU, but it seems likely the military intelligence agency would have exploited his considerable technical skills, knowledge and connections on the Russian cybercrime forums.

Searching on Safronov’s domain uposter[.]ru in Constella Intelligence reveals that this domain was used in 2022 to register an account at a popular Spanish-language discussion forum dedicated to helping applicants prepare for a career in the Guardia Civil, one of Spain’s two national police forces. Pivoting on that Russian IP in Constella shows three other accounts were created at the same Spanish user forum around the same date.

Mark Rasch is a former cybercrime prosecutor for the U.S. Department of Justice who now serves as chief legal officer for the New York cybersecurity firm Unit 221B. Rasch said there has always been a close relationship between the GRU and the Russian hacker community, noting that in the early 2000s the GRU was soliciting hackers with the skills necessary to hack US banks in order to procure funds to help finance Russia’s war in Chechnya.

“The guy is heavily hooked into the Russian cyber community, and that’s useful for intelligence services,” Rasch said. “He could have been infiltrating the community to monitor it for the GRU. Or he could just be a guy wearing a military uniform.”

Arrests in $400M SIM-Swap Tied to Heist at FTX?

1 February 2024 at 13:41

Three Americans were charged this week with stealing more than $400 million in a November 2022 SIM-swapping attack. The U.S. government did not name the victim organization, but there is every indication that the money was stolen from the now-defunct cryptocurrency exchange FTX, which had just filed for bankruptcy on that same day.

A graphic illustrating the flow of more than $400 million in cryptocurrencies stolen from FTX on Nov. 11-12, 2022. Image: Elliptic.co.

An indictment unsealed this week and first reported on by Ars Technica alleges that Chicago man Robert Powell, a.k.a. “R,” “R$” and “ElSwapo1,” was the ringleader of a SIM-swapping group called the “Powell SIM Swapping Crew.” Colorado resident Emily “Em” Hernandez allegedly helped the group gain access to victim devices in service of SIM-swapping attacks between March 2021 and April 2023. Indiana resident Carter Rohn, a.k.a. “Carti,” and “Punslayer,” allegedly assisted in compromising devices.

In a SIM-swapping attack, the crooks transfer the target’s phone number to a device they control, allowing them to intercept any text messages or phone calls sent to the victim, including one-time passcodes for authentication or password reset links sent via SMS.

The indictment states that the perpetrators in this heist stole the $400 million in cryptocurrencies on Nov. 11, 2022 after they SIM-swapped an AT&T customer by impersonating them at a retail store using a fake ID. However, the document refers to the victim in this case only by the name “Victim 1.”

Wired’s Andy Greenberg recently wrote about FTX’s all-night race to stop a $1 billion crypto heist that occurred on the evening of November 11:

“FTX’s staff had already endured one of the worst days in the company’s short life. What had recently been one of the world’s top cryptocurrency exchanges, valued at $32 billion only 10 months earlier, had just declared bankruptcy. Executives had, after an extended struggle, persuaded the company’s CEO, Sam Bankman-Fried, to hand over the reins to John Ray III, a new chief executive now tasked with shepherding the company through a nightmarish thicket of debts, many of which it seemed to have no means to pay.”

“FTX had, it seemed, hit rock bottom. Until someone—a thief or thieves who have yet to be identified—chose that particular moment to make things far worse. That Friday evening, exhausted FTX staffers began to see mysterious outflows of the company’s cryptocurrency, publicly captured on the Etherscan website that tracks the Ethereum blockchain, representing hundreds of millions of dollars worth of crypto being stolen in real time.”

The indictment says the $400 million was stolen over several hours between November 11 and 12, 2022. Tom Robinson, co-founder of the blockchain intelligence firm Elliptic, said the attackers in the FTX heist began to drain FTX wallets on the evening of Nov. 11, 2022 local time, and continuing until the 12th of November.

Robinson said Elliptic is not aware of any other crypto heists of that magnitude occurring on that date.

“We put the value of the cryptoassets stolen at $477 million,” Robinson said. “The FTX administrators have reported overall losses due to “unauthorized third-party transfers” of $413 million – the discrepancy is likely due to subsequent seizure and return of some of the stolen assets. Either way, it’s certainly over $400 million, and we are not aware of any other thefts from crypto exchanges on this scale, on this date.”

The SIM-swappers allegedly responsible for the $400 million crypto theft are all U.S. residents. But there are some indications they had help from organized cybercriminals based in Russia. In October 2023, Elliptic released a report that found the money stolen from FTX had been laundered through exchanges with ties to criminal groups based in Russia.

“A Russia-linked actor seems a stronger possibility,” Elliptic wrote. “Of the stolen assets that can be traced through ChipMixer, significant amounts are combined with funds from Russia-linked criminal groups, including ransomware gangs and darknet markets, before being sent to exchanges. This points to the involvement of a broker or other intermediary with a nexus in Russia.”

Nick Bax, director of analytics at the cryptocurrency wallet recovery firm Unciphered, said the flow of stolen FTX funds looks more like what his team has seen from groups based in Eastern Europe and Russian than anything they’ve witnessed from US-based SIM-swappers.

“I was a bit surprised by this development but it seems to be consistent with reports from CISA [the Cybersecurity and Infrastructure Security Agency] and others that “Scattered Spider” has worked with [ransomware] groups like ALPHV/BlackCat,” Bax said.

CISA’s alert on Scattered Spider says they are a cybercriminal group that targets large companies and their contracted information technology (IT) help desks.

“Scattered Spider threat actors, per trusted third parties, have typically engaged in data theft for extortion and have also been known to utilize BlackCat/ALPHV ransomware alongside their usual TTPs,” CISA said, referring to the group’s signature “Tactics, Techniques an Procedures.”

Earlier this week, KrebsOnSecurity published a story noting that a Florida man recently charged with being part of a SIM-swapping conspiracy is thought to be a key member of Scattered Spider, a hacking group also known as 0ktapus. That group has been blamed for a string of cyber intrusions at major U.S. technology companies during the summer of 2022.

Financial claims involving FTX’s bankruptcy proceedings are being handled by the financial and risk consulting giant Kroll. In August 2023, Kroll suffered its own breach after a Kroll employee was SIM-swapped. According to Kroll, the thieves stole user information for multiple cryptocurrency platforms that rely on Kroll services to handle bankruptcy proceedings.

KrebsOnSecurity sought comment for this story from Kroll, the FBI, the prosecuting attorneys, and Sullivan & Cromwell, the law firm handling the FTX bankruptcy. This story will be updated in the event any of them respond.

Attorneys for Mr. Powell said they do not know who Victim 1 is in the indictment, as the government hasn’t shared that information yet. Powell’s next court date is a detention hearing on Feb. 2, 2024.

Update, Feb. 3, 12:19 p.m. ET: The FBI declined a request to comment.

Fla. Man Charged in SIM-Swapping Spree is Key Suspect in Hacker Groups Oktapus, Scattered Spider

30 January 2024 at 14:07

On Jan. 9, 2024, U.S. authorities arrested a 19-year-old Florida man charged with wire fraud, aggravated identity theft, and conspiring with others to use SIM-swapping to steal cryptocurrency. Sources close to the investigation tell KrebsOnSecurity the accused was a key member of a criminal hacking group blamed for a string of cyber intrusions at major U.S. technology companies during the summer of 2022.

Prosecutors say Noah Michael Urban of Palm Coast, Fla., stole at least $800,000 from at least five victims between August 2022 and March 2023. In each attack, the victims saw their email and financial accounts compromised after suffering an unauthorized SIM-swap, wherein attackers transferred each victim’s mobile phone number to a new device that they controlled.

The government says Urban went by the aliases “Sosa” and “King Bob,” among others. Multiple trusted sources told KrebsOnSecurity that Sosa/King Bob was a core member of a hacking group behind the 2022 breach at Twilio, a company that provides services for making and receiving text messages and phone calls. Twilio disclosed in Aug. 2022 that an intrusion had exposed a “limited number” of Twilio customer accounts through a sophisticated social engineering attack designed to steal employee credentials.

Shortly after that disclosure, the security firm Group-IB published a report linking the attackers behind the Twilio intrusion to separate breaches at more than 130 organizations, including LastPass, DoorDash, Mailchimp, and Plex. Multiple security firms soon assigned the hacking group the nickname “Scattered Spider.”

Group-IB dubbed the gang by a different name — 0ktapus — which was a nod to how the criminal group phished employees for credentials. The missives asked users to click a link and log in at a phishing page that mimicked their employer’s Okta authentication page. Those who submitted credentials were then prompted to provide the one-time password needed for multi-factor authentication.

A booking photo of Noah Michael Urban released by the Volusia County Sheriff.

0ktapus used newly-registered domains that often included the name of the targeted company, and sent text messages urging employees to click on links to these domains to view information about a pending change in their work schedule. The phishing sites used a Telegram instant message bot to forward any submitted credentials in real-time, allowing the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website.

0ktapus often leveraged information or access gained in one breach to perpetrate another. As documented by Group-IB, the group pivoted from its access to Twilio to attack at least 163 of its customers. Among those was the encrypted messaging app Signal, which said the breach could have let attackers re-register the phone number on another device for about 1,900 users.

Also in August 2022, several employees at email delivery firm Mailchimp provided their remote access credentials to this phishing group. According to an Aug. 12 blog post, the attackers used their access to Mailchimp employee accounts to steal data from 214 customers involved in cryptocurrency and finance.

On August 25, 2022, the password manager service LastPass disclosed a breach in which attackers stole some source code and proprietary LastPass technical information, and weeks later LastPass said an investigation revealed no customer data or password vaults were accessed.

However, on November 30, 2022 LastPass disclosed a far more serious breach that the company said leveraged data stolen in the August breach. LastPass said criminal hackers had stolen encrypted copies of some password vaults, as well as other personal information.

In February 2023, LastPass disclosed that the intrusion involved a highly complex, targeted attack against a DevOps engineer who was one of only four LastPass employees with access to the corporate vault. In that incident, the attackers exploited a security vulnerability in a Plex media server that the employee was running on his home network, and succeeded in installing malicious software that stole passwords and other authentication credentials. The vulnerability exploited by the intruders was patched back in 2020, but the employee never updated his Plex software.

As it happens, Plex announced its own data breach one day before LastPass disclosed its initial August intrusion. On August 24, 2022, Plex’s security team urged users to reset their passwords, saying an intruder had accessed customer emails, usernames and encrypted passwords.

KING BOB’S GRAILS

A review of thousands of messages that Sosa and King Bob posted to several public forums and Discord servers over the past two years shows that the person behind these identities was mainly focused on two things: Sim-swapping, and trading in stolen, unreleased rap music recordings from popular artists.

Indeed, those messages show Sosa/King Bob was obsessed with finding new “grails,” the slang term used in some cybercrime discussion channels to describe recordings from popular artists that have never been officially released. It stands to reason that King Bob was SIM-swapping important people in the music industry to obtain these files, although there is little to support this conclusion from the public chat records available.

“I got the most music in the com,” King Bob bragged in a Discord server in November 2022. “I got thousands of grails.”

King Bob’s chats show he was particularly enamored of stealing the unreleased works of his favorite artists — Lil Uzi Vert, Playboi Carti, and Juice Wrld. When another Discord user asked if he has Eminem grails, King Bob said he was unsure.

“I have two folders,” King Bob explained. “One with Uzi, Carti, Juicewrld. And then I have ‘every other artist.’ Every other artist is unorganized as fuck and has thousands of random shit.”

King Bob’s posts on Discord show he quickly became a celebrity on Leaked[.]cx, one of most active forums for trading, buying and selling unreleased music from popular artists. The more grails that users share with the Leaked[.]cx community, the more their status and access on the forum grows.

The last cache of Leaked dot cx indexed by the archive.org on Jan. 11, 2024.

And King Bob shared a large number of his purloined tunes with this community. Still others he tried to sell. It’s unclear how many of those sales were ever consummated, but it is not unusual for a prized grail to sell for anywhere from $5,000 to $20,000.

In mid-January 2024, several Leaked[.]cx regulars began complaining that they hadn’t seen King Bob in a while and were really missing his grails. On or around Jan. 11, the same day the Justice Department unsealed the indictment against Urban, Leaked[.]cx started blocking people who were trying to visit the site from the United States.

Days later, frustrated Leaked[.]cx users speculated about what could be the cause of the blockage.

“Probs blocked as part of king bob investigation i think?,” wrote the user “Plsdontarrest.” “Doubt he only hacked US artists/ppl which is why it’s happening in multiple countries.”

FORESHADOWING

On Sept. 21, 2022, KrebsOnSecurity told the story of a “Foreshadow,” the nickname chosen by a Florida teenager who was working for a SIM-swapping crew when he was abducted, beaten and held for a $200,000 ransom. A rival SIM-swapping group claimed that Foreshadow and his associates had robbed them of their fair share of the profits from a recent SIM-swap.

In a video released by his abductors on Telegram, a bloodied, battered Foreshadow was made to say they would kill him unless the ransom was paid.

As I wrote in that story, Foreshadow appears to have served as a “holder” — a term used to describe a low-level member of any SIM-swapping group who agrees to carry out the riskiest and least rewarding role of the crime: Physically keeping and managing the various mobile devices and SIM cards that are used in SIM-swapping scams.

KrebsOnSecurity has since learned that Foreshadow was a holder for a particularly active SIM-swapper who went by “Elijah,” which was another nickname that prosecutors say Urban used.

Shortly after Foreshadow’s hostage video began circulating on Telegram and Discord, multiple known actors in the SIM-swapping space told everyone in the channels to delete any previous messages with Foreshadow, claiming he was fully cooperating with the FBI.

This was not the first time Sosa and his crew were hit with violent attacks from rival SIM-swapping groups. In early 2022, a video surfaced on a popular cybercrime channel purporting to show attackers hurling a brick through a window at an address that matches the spacious and upscale home of Urban’s parents in Sanford, Fl.

“Brickings” are among the “violence-as-a-service” offerings broadly available on many cybercrime channels. SIM-swapping and adjacent cybercrime channels are replete with job offers for in-person assignments and tasks that can be found if one searches for posts titled, “If you live near,” or “IRL job” — short for “in real life” job.

A number of these classified ads are in service of performing brickings, where someone is hired to visit a specific address and toss a brick through the target’s window. Other typical IRL job offers involve tire slashings and even drive-by shootings.

THE COM

Sosa was known to be a top member of the broader cybercriminal community online known as “The Com,” wherein hackers boast loudly about high-profile exploits and hacks that almost invariably begin with social engineering — tricking people over the phone, email or SMS into giving away credentials that allow remote access to corporate internal networks.

Sosa also was active in a particularly destructive group of accomplished criminal SIM-swappers known as “Star Fraud.” Cyberscoop’s AJ Vicens reported last year that individuals within Star Fraud were likely involved in the high-profile Caesars Entertainment an MGM Resorts extortion attacks.

“ALPHV, an established ransomware-as-a-service operation thought to be based in Russia and linked to attacks on dozens of entities, claimed responsibility for Caesars and MGM attacks in a note posted to its website earlier this month,” Vicens wrote. “Experts had said the attacks were the work of a group tracked variously as UNC 3944 or Scattered Spider, which has been described as an affiliate working with ALPHV made up of people in the United States and Britain who excel at social engineering.”

In February 2023, KrebsOnSecurity published data taken from the Telegram channels for Star Fraud and two other SIM-swapping groups showing these crooks focused on SIM-swapping T-Mobile customers, and that they collectively claimed access to T-Mobile on 100 separate occasions over a 7-month period in 2022.

The SIM-swapping groups were able to switch targeted phone numbers to another device on demand because they constantly phished T-Mobile employees into giving up credentials to employee-only tools. In each of those cases the goal was the same: Phish T-Mobile employees for access to internal company tools, and then convert that access into a cybercrime service that could be hired to divert any T-Mobile user’s text messages and phone calls to another device.

Allison Nixon, chief research officer at the New York cybersecurity consultancy Unit 221B, said the increasing brazenness of many Com members is a function of how long it has taken federal authorities to go after guys like Sosa.

“These incidents show what happens when it takes too long for cybercriminals to get arrested,” Nixon said. “If governments fail to prioritize this source of threat, violence originating from the Internet will affect regular people.”

NO FIXED ADDRESS

The Daytona Beach News-Journal reports that Urban was arrested Jan. 9 and his trial is scheduled to begin in the trial term starting March 4 in Jacksonville. The publication said the judge overseeing Urban’s case denied bail because the defendant was a strong flight risk.

At Urban’s arraignment, it emerged that he had no fixed address and had been using an alias to stay at an Airbnb. The judge reportedly said that when a search warrant was executed at Urban’s residence, the defendant was downloading programs to delete computer files.

What’s more, the judge explained, despite telling authorities in May that he would not have any more contact with his co-conspirators and would not engage in cryptocurrency transactions, he did so anyway.

Urban entered a plea of not guilty. Urban’s court-appointed attorney said her client would have no comment at this time.

Prosecutors charged Urban with eight counts of wire fraud, one count of conspiracy to commit wire fraud, and five counts of aggravated identity theft. According to the government, if convicted Urban faces up to 20 years in federal prison on each wire fraud charge. He also faces a minimum mandatory penalty of two years in prison for the aggravated identity offenses, which will run consecutive to any other prison sentence imposed.

Who is Alleged Medibank Hacker Aleksandr Ermakov?

26 January 2024 at 13:12

Authorities in Australia, the United Kingdom and the United States this week levied financial sanctions against a Russian man accused of stealing data on nearly 10 million customers of the Australian health insurance giant Medibank. 33-year-old Aleksandr Ermakov allegedly stole and leaked the Medibank data while working with one of Russia’s most destructive ransomware groups, but little more is shared about the accused. Here’s a closer look at the activities of Mr. Ermakov’s alleged hacker handles.

The allegations against Ermakov mark the first time Australia has sanctioned a cybercriminal. The documents released by the Australian government included multiple photos of Mr. Ermakov, and it was clear they wanted to send a message that this was personal.

It’s not hard to see why. The attackers who broke into Medibank in October 2022 stole 9.7 million records on current and former Medibank customers. When the company refused to pay a $10 million ransom demand, the hackers selectively leaked highly sensitive health records, including those tied to abortions, HIV and alcohol abuse.

The U.S. government says Ermakov and the other actors behind the Medibank hack are believed to be linked to the Russia-backed cybercrime gang REvil.

“REvil was among the most notorious cybercrime gangs in the world until July 2021 when they disappeared. REvil is a ransomware-as-a-service (RaaS) operation and generally motivated by financial gain,” a statement from the U.S. Department of the Treasury reads. “REvil ransomware has been deployed on approximately 175,000 computers worldwide, with at least $200 million paid in ransom.”

The sanctions say Ermakov went by multiple aliases on Russian cybercrime forums, including GustaveDore, JimJones, and Blade Runner. A search on the handle GustaveDore at the cyber intelligence platform Intel 471 shows this user created a ransomware affiliate program in November 2021 called Sugar (a.k.a. Encoded01), which focused on targeting single computers and end-users instead of corporations.

An ad for the ransomware-as-a-service program Sugar posted by GustaveDore warns readers against sharing information with security researchers, law enforcement, or “friends of Krebs.”

In November 2020, Intel 471 analysts concluded that GustaveDore’s alias JimJones “was using and operating several different ransomware strains, including a private undisclosed strain and one developed by the REvil gang.”

In 2020, GustaveDore advertised on several Russian discussion forums that he was part of a Russian technology firm called Shtazi, which could be hired for computer programming, web development, and “reputation management.” Shtazi’s website remains in operation today.

A Google-translated version of Shtazi dot ru. Image: Archive.org.

The third result when one searches for shtazi[.]ru in Google is an Instagram post from a user named Mikhail Borisovich Shefel, who promotes Shtazi’s services as if it were also his business. If this name sounds familiar, it’s because in December 2023 KrebsOnSecurity identified Mr. Shefel as “Rescator,” the cybercriminal identity tied to tens of millions of payment cards that were stolen in 2013 and 2014 from big box retailers Target and Home Depot, among others.

How close was the connection between GustaveDore and Mr. Shefel? The Treasury Department’s sanctions page says Ermakov used the email address ae.ermak@yandex.ru. A search for this email at DomainTools.com shows it was used to register just one domain name: millioner1[.]com. DomainTools further finds that a phone number tied to Mr. Shefel (79856696666) was used to register two domains: millioner[.]pw, and shtazi[.]net.

The December 2023 story here that outed Mr. Shefel as Rescator noted that Shefel recently changed his last name to “Lenin” and had launched a service called Lenin[.]biz that sells physical USSR-era Ruble notes bearing the image of Vladimir Lenin, the founding father of the Soviet Union. The Instagram account for Mr. Shefel includes images of stacked USSR-era Ruble notes, as well as multiple links to Shtazi.

The Instagram account of Mikhail Borisovich Shefel, aka MikeMike aka Rescator.

Intel 471’s research revealed Ermakov was affiliated in some way with REvil because the stolen Medibank data was published on a blog that had one time been controlled by REvil affiliates who carried out attacks and paid an affiliate fee to the gang.

But by the time of the Medibank hack, the REvil group had mostly scattered after a series of high-profile attacks led to the group being disrupted by law enforcement. In November 2021, Europol announced it arrested seven REvil affiliates who collectively made more than $230 million worth of ransom demands since 2019. At the same time, U.S. authorities unsealed two indictments against a pair of accused REvil cybercriminals.

“The posting of Medibank’s data on that blog, however, indicated a connection with that group, although the connection wasn’t clear at the time,” Intel 471 wrote. “This makes sense in retrospect, as Ermakov’s group had also been a REvil affiliate.”

It is easy to dismiss sanctions like these as ineffective, because as long as Mr. Ermakov remains in Russia he has little to fear of arrest. However, his alleged role as an apparent top member of REvil paints a target on him as someone who likely possesses large sums of cryptocurrency, said Patrick Gray, the Australian co-host and founder of the security news podcast Risky Business.

“I’ve seen a few people poo-poohing the sanctions…but the sanctions component is actually less important than the doxing component,” Gray said. “Because this guy’s life just got a lot more complicated. He’s probably going to have to pay some bribes to stay out of trouble. Every single criminal in Russia now knows he is a vulnerable 33 year old with an absolute ton of bitcoin. So this is not a happy time for him.”

Update, Feb. 21, 1:10 p.m. ET: The Russian security firm F.A.C.C.T reports that Ermakov has been arrested in Russia, and charged with violating domestic laws that prohibit the creation, use and distribution of malicious computer programs.

“During the investigation, several defendants were identified who were not only promoting their ransomware, but also developing custom-made malicious software, creating phishing sites for online stores, and driving user traffic to fraudulent schemes popular in Russia and the CIS,” F.A.C.C.T. wrote. “Among those detained was the owner of the nicknames blade_runner, GistaveDore, GustaveDore, JimJones.”

E-Crime Rapper ‘Punchmade Dev’ Debuts Card Shop

17 January 2024 at 12:00

The rapper and social media personality Punchmade Dev is perhaps best known for his flashy videos singing the praises of a cybercrime lifestyle. With memorable hits such as “Internet Swiping” and “Million Dollar Criminal” earning millions of views, Punchmade has leveraged his considerable following to peddle tutorials on how to commit financial crimes online. But until recently, there wasn’t much to support a conclusion that Punchmade was actually doing the cybercrime things he promotes in his songs.

Images from Punchmade Dev’s Twitter/X account show him displaying bags of cash and wearing a functional diamond-crusted payment card skimmer.

Punchmade Dev’s most controversial mix — a rap called “Wire Fraud Tutorial” — was taken down by Youtube last summer for violating the site’s rules. Punchmade shared on social media that the video’s removal was prompted by YouTube receiving a legal process request from law enforcement officials.

The 24-year-old rapper told reporters he wasn’t instructing people how to conduct wire fraud, but instead informing his fans on how to avoid being victims of wire fraud. However, this is difficult to discern from listening to the song, which sounds very much like a step-by-step tutorial on how to commit wire fraud.

“Listen up, I’m finna show y’all how to hit a bank,” Wire Fraud Tutorial begins. “Just pay attention, this is a quick way to jug in any state. First you wanna get a bank log from a trusted site. Do your research because the information must be right.”

And even though we’re talking about an individual who regularly appears in videos wearing a half-million dollars worth of custom jewelry draped around his arm and neck (including the functional diamond-encrusted payment card skimming device pictured above), there’s never been much evidence that Punchmade was actually involved in committing cybercrimes himself. Even his most vocal critics acknowledged that the whole persona could just be savvy marketing.

That changed recently when Punchmade’s various video and social media accounts began promoting a new web shop that is selling stolen payment cards and identity data, as well as hacked financial accounts and software for producing counterfeit checks.

Punchmade Dev's shop.

The official Punchmadedev account on Instagram links to many of the aforementioned rap videos and tutorials on cybercriming, as well as to Punchmadedev’s other profiles and websites. Among them is mainpage[.]me/punchmade, which includes the following information for “Punchmade Empire ®

-212,961 subscribers

24/7 shop: https://punchmade[.]atshop[.]io

Visiting that @whopunchmade Telegram channel shows this user is promoting punchmade[.]atshop[.]io, which is currently selling hacked bank accounts and payment cards with high balances.

Clicking “purchase” on the C@sh App offering, for example, shows that for $80 the buyer will receive logins to Cash App accounts with balances between $3,000 and $5,000. “If you buy this item you’ll get my full support on discord/telegram if there is a problem!,” the site promises. Purchases can be made in cryptocurrencies, and checking out prompts one to continue payment at Coinbase.com.

Another item for sale, “Fullz + Linkable CC,” promises “ID Front + Back, SSN with 700+ Credit Score, and Linkable CC” or credit card. That also can be had for $80 in crypto.

WHO IS PUNCHMADE DEV?

Punchmade has fashioned his public persona around a collection of custom-made, diamond-covered necklaces that are as outlandish and gaudy as they are revelatory. My favorite shot from one of Punchmade’s videos features at least three of these monstrosities: One appears to be a boring old diamond and gold covered bitcoin, but the other two necklaces tell us something about where Punchmade is from:

Notice the University of Kentucky logo, and the Lexington, Ky skyline.

One of them includes the logo and mascot of the University of Kentucky. The other, an enormous diamond studded skyline, appears to have been designed based on the skyline in Lexington, Ky:

The “About” page on Punchmade Dev’s Spotify profile describes him as “an American artist, rapper, musician, producer, director, entrepreneur, actor and investor.” “Punchmade Dev is best known for his creative ways to use technology, video gaming, and social media to build a fan base,” the profile continues.

The profile explains that he launched his own record label in 2021 called Punchmade Records, where he produces his own instrumentals and edits his own music videos.

A search on companies that include the name “punchmade” at the website of the Kentucky Secretary of State brings up just one record: OBN Group LLC, in Lexington, Ky. This November 2021 record includes a Certificate of Assumed Name, which shows that Punchmade LLC is the assumed name of OBN Group LLC.

The president of OBN Group LLC is listed as Devon Turner. A search on the Secretary of State website for other businesses tied to Devon Turner reveals just one other record: A now-defunct entity called DevTakeFlightBeats Inc.

The breach tracking service Constella Intelligence finds that Devon Turner from Lexington, Ky. used the email address obndevpayments@gmail.com. A lookup on this email at DomainTools.com shows it was used to register the domain foreverpunchmade[.]com, which is registered to a Devon Turner in Lexington, Ky. A copy of this site at archive.org indicates it once sold Punchmade Dev-branded t-shirts and other merchandise.

Mr. Turner did not respond to multiple requests for comment.

Searching online for Devon Turner and “Punchmade” brings up a video from @brainjuiceofficial, a YouTube channel that focuses on social media celebrities. @Brainjuiceofficial says Turner was born in October 2000, the oldest child of a single mother of five whose husband was not in the picture.

Devon Turner, a.k.a. “Punchmade Dev,” in an undated photo.

The video says the six-foot five Turner played basketball, track and football in high school, but that he gradually became obsessed with playing the video game NBA 2K17 and building a following of people watching him play the game competitively online.

According to this brief documentary, Turner previously streamed his NBA 2K17 videos on a YouTube channel called DevTakeFlight, although he originally went by the nickname OBN Dev.

“Things may eventually catch up to Devon if he isn’t careful,” @Brainjuiceofficial observed, noting that Turner has been shot at before, and also robbed at an ATM while flexing a bunch of cash for a picture and wearing $500k in jewelry. “Although you have a lot of people that are into what you do, there are a lot of people waiting for you to slip up.”

Alleged Extortioner of Psychotherapy Patients Faces Trial

16 November 2023 at 14:59

Prosecutors in Finland this week commenced their criminal trial against Julius Kivimäki, a 26-year-old Finnish man charged with extorting a once popular and now-bankrupt online psychotherapy practice and thousands of its patients. In a 2,200-page report, Finnish authorities laid out how they connected the extortion spree to Kivimäki, a notorious hacker who was convicted in 2015 of perpetrating tens of thousands of cybercrimes, including data breaches, payment fraud, operating a botnet and calling in bomb threats.

In November 2022, Kivimäki was charged with attempting to extort money from the Vastaamo Psychotherapy Center. In that breach, which occurred in October 2020, a hacker using the handle “Ransom Man” threatened to publish patient psychotherapy notes if Vastaamo did not pay a six-figure ransom demand.

Vastaamo refused, so Ransom Man shifted to extorting individual patients — sending them targeted emails threatening to publish their therapy notes unless paid a 500-euro ransom. When Ransom Man found little success extorting patients directly, they uploaded to the dark web a large compressed file containing all of the stolen Vastaamo patient records.

Security experts soon discovered Ransom Man had mistakenly included an entire copy of their home folder, where investigators found many clues pointing to Kivimäki’s involvement. By that time, Kivimäki was no longer in Finland, but the Finnish government nevertheless charged Kivimäki in absentia with the Vastaamo hack. The 2,200-page evidence document against Kivimäki suggests he enjoyed a lavish lifestyle while on the lam, frequenting luxury resorts and renting fabulously expensive cars and living quarters.

But in February 2023, Kivimäki was arrested in France after authorities there responded to a domestic disturbance call and found the defendant sleeping off a hangover on the couch of a woman he’d met the night before. The French police grew suspicious when the 6′ 3″ blonde, green-eyed man presented an ID that stated he was of Romanian nationality.

A redacted copy of an ID Kivimaki gave to French authorities claiming he was from Romania.

Finnish prosecutors showed that Kivimäki’s credit card had been used to pay for the virtual server that hosted the stolen Vastaamo patient notes. What’s more, the home folder included in the Vastaamo patient data archive also allowed investigators to peer into other cybercrime projects of the accused, including domains that Ransom Man had access to as well as a lengthy history of commands he’d executed on the rented virtual server.

Some of those domains allegedly administered by Kivimäki were set up to smear the reputations of different companies and individuals. One of those was a website that claimed to have been authored by a person who headed up IT infrastructure for a major bank in Norway which discussed the idea of legalizing child sexual abuse.

Another domain hosted a fake blog that besmirched the reputation of a Tulsa, Okla. man whose name was attached to blog posts about supporting the “white pride” movement and calling for a pardon of the Oklahoma City bomber Timothy McVeigh.

Kivimäki appears to have sought to sully the name of this reporter as well. The 2,200-page document shows that Kivimäki owned and operated the domain krebsonsecurity[.]org, which hosted various hacking tools that Kivimäki allegedly used, including programs for mass-scanning the Internet for systems vulnerable to known security flaws, as well as scripts for cracking database server usernames and passwords, and downloading databases.

Ransom Man inadvertently included a copy of his home directory in the leaked Vastaamo patient data. A lengthy history of the commands run by that user show they used krebsonsecurity-dot-org to host hacking and scanning tools.

Mikko Hyppönen, chief research officer at WithSecure (formerly F-Secure), said the Finnish authorities have done “amazing work,” and that “it’s rare to have this much evidence for a cybercrime case.”

Petteri Järvinen is a respected IT expert and author who has been following the trial, and he said the prosecution’s case so far has been strong.

“The National Bureau of Investigation has done a good job and Mr Kivimäki for his part some elementary mistakes,” Järvinen wrote on LinkedIn. “This sends an important message: online crime does not pay. Traces are left in the digital world too, even if it is very tedious for the police to collect them from servers all around the world.”

Antti Kurittu is an information security specialist and a former criminal investigator. In 2013, Kurittu worked on an investigation involving Kivimäki’s use of the Zbot botnet, among other activities Kivimäki engaged in as a member of the hacker group Hack the Planet (HTP). Kurittu said it remains to be seen if the prosecution can make their case, and if the defense has any answers to all of the evidence presented.

“Based on the public pretrial investigation report, it looks like the case has a lot of details that seem very improbable to be coincidental,” Kurittu told KrebsOnSecurity. “For example, a full copy of the Vastaamo patient database was found on a server that belonged to Scanifi, a company with no reasonable business that Kivimäki was affiliated with. The leaked home folder contents were also connected to Kivimäki and were found on servers that were under his control.”

The Finnish daily yle.fi reports that Kivimäki’s lawyers sought to have their client released from confinement for the remainder of his trial, noting that the defendant has already been detained for eight months.

The court denied that request, saying the defendant was still a flight risk. Kivimäki’s trial is expected to continue until February 2024, in part to accommodate testimony from a large number of victims. Prosecutors are seeking a seven-year sentence for Kivimäki.

Who’s Behind the SWAT USA Reshipping Service?

6 November 2023 at 08:51

Last week, KrebsOnSecurity broke the news that one of the largest cybercrime services for laundering stolen merchandise was hacked recently, exposing its internal operations, finances and organizational structure. In today’s Part II, we’ll examine clues about the real-life identity of “Fearlless,” the nickname chosen by the proprietor of the SWAT USA Drops service.

Based in Russia, SWAT USA recruits people in the United States to reship packages containing pricey electronics that are purchased with stolen credit cards. As detailed in this Nov. 2 story, SWAT currently employs more than 1,200 U.S. residents, all of whom will be cut loose without a promised payday at the end of their first month reshipping stolen goods.

The current co-owner of SWAT, a cybercriminal who uses the nickname “Fearlless,” operates primarily on the cybercrime forum Verified. This Russian-language forum has tens of thousands of members, and it has suffered several hacks that exposed more than a decade’s worth of user data and direct messages.

January 2021 posts on Verified show that Fearlless and his partner Universalo purchased the SWAT reshipping business from a Verified member named SWAT, who’d been operating the service for years. SWAT agreed to transfer the business in exchange for 30 percent of the net profit over the ensuing six months.

Cyber intelligence firm Intel 471 says Fearlless first registered on Verified in February 2013. The email address Fearlless used on Verified leads nowhere, but a review of Fearlless’ direct messages on Verified indicates this user originally registered on Verified a year earlier as a reshipping vendor, under the alias “Apathyp.”

There are two clues supporting the conclusion that Apathyp and Fearlless are the same person. First, the Verified administrators warned Apathyp he had violated the forum’s rules barring the use of multiple accounts by the same person, and that Verified’s automated systems had detected that Apathyp and Fearlless were logging in from the same device.  Second, in his earliest private messages on Verified, Fearlless told others to contact him on an instant messenger address that Apathyp had claimed as his.

Intel 471 says Apathyp registered on Verified using the email address triploo@mail.ru. A search on that email address at the breach intelligence service Constella Intelligence found that a password commonly associated with it was “niceone.” But the triploo@mail.ru account isn’t connected to much else that’s interesting except a now-deleted account at Vkontakte, the Russian answer to Facebook.

However, in Sept. 2020, Apathyp sent a private message on Verified to the owner of a stolen credit card shop, saying his credentials no longer worked. Apathyp told the proprietor that his chosen password on the service was “12Apathy.”

A search on that password at Constella reveals it was used by just four different email addresses, two of which are particularly interesting: gezze@yandex.ru and gezze@mail.ru. Constella discovered that both of these addresses were previously associated with the same password as triploo@mail.ru — “niceone,” or some variation thereof.

Constella found that years ago gezze@mail.ru was used to create a Vkontakte account under the name Ivan Sherban (former password: “12niceone“) from Magnitogorsk, an industrial city in the southern region of Russia. That same email address is now tied to a Vkontakte account for an Ivan Sherban who lists his home as Saint Petersburg, Russia. Sherban’s profile photo shows a heavily tattooed, muscular and recently married individual with his beautiful new bride getting ready to drive off in a convertible sports car.

A pivotal clue for validating the research into Apathyp/Fearlless came from the identity intelligence firm myNetWatchman, which found that gezze@mail.ru at one time used the passwords “геззи1991” (gezze1991) and “gezze18081991.”

Care to place a wager on when Vkontakte says is Mr. Sherban’s birthday? Ten points if you answered August 18 (18081991).

Mr. Sherban did not respond to multiple requests for comment.
