Death Threats, Laptop Farms, Stolen IDs: Inside North Korea’s Job Scam

14 October 2026 at 03:49

North Korean IT workers

North Korean IT workers are paying Americans to help them get and keep remote jobs at U.S. companies, the FBI said in an updated FBI public service announcement. At the same time, the Justice Department announced charges, two arrests, and the seizure of about 187 computer devices linked to the scheme. The FBI said these workers use stolen identities, extort victims, and threaten physical violence to demand payments. North Korea's government receives an estimated 85 to 90 percent of the revenue they generate, money that helps fund its nuclear weapons and other military programs.

How North Korean IT Workers Use American Facilitators

According to the FBI, North Korean IT workers are hiring Americans for a growing list of tasks. These include appearing on camera, sitting for job interviews, verifying fake identities, lending social media or professional networking accounts, shipping packages, completing urinalysis tests or fingerprint submissions, and keeping work laptops online from their homes. [caption id="attachment_114769" align="aligncenter" width="600"]North Korean IT workers Image Source: FBI Cyber Division[/caption] The FBI said some workers deliberately target people under financial stress, looking for those more likely to follow instructions without questions if paid. Taking part in these activities is illegal. Home setups that host company laptops, known as laptop farms, have helped the workers hide their locations for years. The FBI said they now run more laptop farms with fewer laptops at each to avoid single points of failure. Some also land remote IT jobs and then subcontract the work to freelancers in Pakistan, India, Nigeria, or nearby countries for a fraction of the salary.

Extortion, Threats, and Identity Theft

Identity theft sits at the center of the scheme. Most names and addresses given to employers come from stolen identities, and workers often buy accounts from identity verification providers to check that stolen details will pass background checks. The FBI said that after being fired, some workers made death threats against former managers and their families to collect more money. Others threatened to leak sensitive corporate data unless paid large lump sums. Some hired U.S.-based facilitators to show up in person at victim companies to intimidate staff. The workers also target jobs requiring U.S. government security clearances, positions with cleared defense contractors, and active-duty U.S. military members to host laptops.

Justice Department Charges Linked to North Korean IT Workers

In Ohio, a four-count indictment charges a scheme that ran from 2019 to around July 2025. U.S. nationals Michael James Bostelle of Pennsylvania and Juan Cecilio Pena Carrillo of Texas were arrested. Ten China-based individuals were also charged, and two more defendants remain under seal. Prosecutors say the scheme affected more than 70 U.S. employers and generated about $3 million, believed to have gone to sanctioned DPRK-controlled entities. Victims included health care, communications, cyber support, retail, and manufacturing firms across Ohio, 16 other states, and the District of Columbia. Under Operation Lonestar Roundup, the FBI carried out searches and other actions at more than 40 Texas residences between Sept. 21 and Sept. 25. Agents seized about 187 laptops and KVM devices. Cybersecurity firm CrowdStrike tracks the group as "Famous Chollima. FBI Cyber Division Assistant Director Brett Leatherman said 14 individuals have been charged and called close coordination with the private sector central to the operation.

What Companies Should Know About North Korean IT Workers

The FBI said no single red flag reliably identifies North Korean IT workers. It recommends an "identity in depth" approach, using layered checks throughout employment. Warning signs include remote desktop tools such as AnyDesk and TeamViewer, KVM over IP devices like TinyPilot and PiKVM, unrelated software on work devices, and frequent changes in bank accounts or addresses. Using E-Verify, requiring a U.S. passport, and live identity checks can add friction, the FBI said, while relying only on name ban lists may block real applicants. Individuals who receive threats should call 911. Victims or anyone approached can contact a local FBI field office and file a complaint at www.ic3.gov. The State Department has offered rewards of up to $5 million for information that disrupts North Korea's illicit financial activities.

WaterPlum Hackers Steal $10.7M in Crypto From IT Workers

21 September 2026 at 02:52

WaterPlum

A North Korean cyber actor group known as WaterPlum, also referred to as "Contagious Interview," has infected at least 30,000 devices across more than 100 countries. The group has been stealing cryptocurrency from IT professionals worldwide. A joint advisory was issued on September 18, 2026, by Japan's National Police Agency and National Cybersecurity Office, the US FBI and Department of Defense Cyber Crime Center, Australia's Signals Directorate, and Germany's Federal Intelligence Service and Federal Office for the Protection of the Constitution.

How WaterPlum Hackers Operate

The agencies assess that WaterPlum actors and certain North Korean IT workers operate under the 313 General Bureau of the Munitions Industry Department, part of the Workers' Party of Korea's Central Committee. The group poses as prospective employers, targeting software developers and IT professionals by impersonating artificial intelligence, cryptocurrency, or non-fungible token companies, and by using recruiting services. During fake technical interviews, victims are instructed to download files to complete coding assignments or fix errors on video calls. These files carry malicious Node Package Manager packages embedded with BeaverTail malware, InvisibleFerret, OtterCookie, OtterCandy, or StoatWaffle. Once installed, the malware grants backdoor access, allowing Remote Access Trojans to maintain persistence while infostealers exfiltrate wallet credentials, browser passwords, clipboard data, keystrokes, and identification documents to command-and-control servers.

Scale of the Cryptocurrency Theft

Between December 2025 and July 2026, WaterPlum exfiltrated funds or credentials from over 7,000 cryptocurrency wallets, transferring 1.7 billion Japanese yen, equivalent to 10.71 million USD, to North Korea. Primary targets included web designers, engineers, and specialists in blockchain and Web3 technologies.

Role of Laptop Farms

The advisory also details how North Korean IT workers generate foreign currency through "laptop farms," locations, often an enabler's residence, where employment computers are remotely controlled by workers based in North Korea, China, Russia, and occasionally Africa or Southeast Asia. Enablers supply identification images, bank accounts, and internet connections, then forward payments to the workers after taking a cut. Japanese authorities dismantled a laptop farm for the first time domestically, uncovering evidence of several hundred million yen transferred abroad in cryptocurrency. A related case involved a suspected North Korean applicant at a Japanese cryptocurrency exchange in May 2025, who submitted a forged resume, accessed the recruitment portal via VPN, and displayed mismatched language skills during a video interview. The company declined to hire the applicant, and no damage occurred.

Warning Signs and Recommended Countermeasures

The agencies list red flags including refusal of in-person meetings, requests for cryptocurrency payment, background voices during calls, and repeated video freezes. Recommended defenses include avoiding execution of untrusted code outside a sandbox, treating VSCode projects with caution using "Restricted Mode," deploying Endpoint Detection and Response tools, and immediately disconnecting compromised devices from the internet. Victims are advised to assume wallet data has been exposed, create new wallets on separate devices, and perform full operating system resets.

International Cooperation Continues

The FBI stated it continues to prosecute US-based facilitators who assist North Korean IT workers, while Japanese and American authorities pledged ongoing cooperation to expose revenue-generation schemes benefiting the Kim regime. The advisory noted that WaterPlum and North Korean IT worker operations shared overlapping IP addresses across laptop farms, crowdsourcing platforms, and job applications, indicating coordinated infrastructure. Companies and individual IT professionals are urged to review the tactics outlined in the advisory and strengthen hiring verification processes to prevent further infiltration.

Fake Apps, Real Spies: How Iran Tracks Dissidents Through Telegram

18 September 2026 at 02:12

Iranian cyber actors

Iranian cyber actors are using a malware family known as HEAVYGRAM, also tracked as CHOSEN BRICK, to target dissidents, journalists, and opposition groups worldwide, according to a recent FBI FLASH report and a joint advisory from the UK National Cyber Security Centre (NCSC), the US FBI, and the Netherlands' General Intelligence and Security Service (AIVD). The FBI assesses that the malware is deployed on behalf of the Government of Iran's Ministry of Intelligence and Security (MOIS) to collect intelligence, conduct data leaks, and cause reputational harm to targets. The joint advisory adds that Iran almost certainly uses cyber activity to support repression of individuals seen as threats to the regime.

Who Is Being Targeted by Iranian Cyber Actors

The victim profile includes Iranian dissidents, journalists opposed to Iran, members of organizations with views countering Government of Iran narratives, and other individuals the Iranian government perceives as threats. The joint advisory notes that CHOSEN BRICK has been used against individuals in the UK, US, and Netherlands since at least 2025, and that personal details of some victims have appeared on pro-Iranian leak sites, increasing risks to their personal safety. In some cases, Iranian intelligence services have plotted to kidnap or conduct lethal operations against individuals abroad who are seen as enemies of the regime.

Social Engineering and Delivery

Iranian cyber actors rely heavily on social engineering to deliver their malware. Actors communicate with targets through platforms such as Telegram, WhatsApp, and Instagram, often posing as individuals known to the target or as technical support from the messaging platform. The joint advisory notes that actors research targets in advance to appear credible, and often initiate contact through a target's work device before shifting to personal devices if the initial delivery attempt fails or risks detection. Victims are persuaded to download files disguised as legitimate applications, including Pictory, RunwayML, Norton Antivirus, Telegram, Adobe Flash Player, and KeePass, or files appearing to be MRI scan results. The FBI notes that some victims downloaded AnyDesk and provided access strings, while others downloaded malware masquerading as a program installer. The malware targets only the Windows operating system.

Persistence and Telegram Command and Control

Once installed, the malware achieves persistence by adding registry keys, most often within the Run key at HKCU\Software\Microsoft\Windows\CurrentVersion\Run, so it runs automatically at user login. It also adds exclusions to Microsoft Defender antivirus to evade detection. The malware then connects to Telegram command-and-control infrastructure, with each victim device linked to a unique Telegram Bot ID to prevent cross-contamination between victims. Through Telegram, the malware can enumerate running processes and system information, capture screen content, enable the microphone to record audio, copy Telegram and WhatsApp data from browsers, download additional files, delete files, steal email content, and wipe the computer system. Files and data are exfiltrated through the Telegram bot and cloud object stores such as VultrObjects and StorjShare. Recent variants use HTTPS/SOCKS5 proxies to obscure the use of Telegram bots.

FBI Recommendations

The FBI recommends caution regarding communications from unknown individuals, keeping devices updated, downloading software only from trusted sources, enabling antivirus software, using strong unique passwords with multi-factor authentication, and reporting suspicious messages. The NCSC, FBI, and AIVD jointly recommend phishing-resistant multi-factor authentication, application allowlisting, email scanning security features, and endpoint and network monitoring. Organizations concerned about a potential HEAVYGRAM or CHOSEN BRICK infection are advised to contact their IT providers and check both corporate and personal devices, since the actors also target individuals outside their workplace systems.

China-Linked Fire Ant Turned Cisco Routers, TACACS Servers Into Espionage Platforms

1 September 2026 at 10:01

Cross-section illustration of a network router with a covert red tunnel passing through it and log entries fading to blank, representing Fire Ant espionage on Cisco IOS XR routers and TACACS servers.

The China-nexus espionage group Fire Ant has moved from compromising virtualization platforms to implanting Cisco IOS XR routers and TACACS authentication servers. They are using them to capture traffic, harvest administrator credentials and suppress the logs defenders rely on, said researchers at Sygnia, an incident response firm.

Researchers first documented Fire Ant in July 2025 for deep intrusions into VMware ESXi and vCenter environments. The new report describes the same actor operating a layer lower, in what researchers call the trust layer — the routers, authentication servers and Linux management hosts that carry traffic, authorize administrators and record what happened.

Researchers assess a strong overlap with UNC3886, the China-linked group Google's Mandiant tracks for targeting network edge and virtualization systems, while noting the tooling has evolved rather than been reused wholesale. The activity is distinct from the Salt Typhoon and Volt Typhoon campaigns.

On Cisco IOS XR routers, the operators deployed custom control-plane malware and created generic routing encapsulation tunnel interfaces that left no trace in device configuration files.

On authentication infrastructure, a previously unreported toolkit that the researchers named TacTap injected a malicious library into the tac_plus daemon to capture credentials as administrators authenticated, storing them with simple XOR obfuscation.

A second new implant, BridgeAgent, ran on Linux jump hosts disguised as a Zabbix monitoring agent and persisted through a systemd unit.

Anti-forensic work was central to the operation. Researchers said the actor modified syslog functions to filter and delete selected records, rewrote wtmp and utmp login records, suppressed authentication logging, filtered command output, disabled SELinux and altered firewall rules. Backdoors were triggered by magic strings inside network packets rather than by listening ports, leaving little for port-based detection to find, and some components had lain dormant since 2025.

Asaf Perlman, Sygnia's director of incident response, said the group's aim went beyond individual machines. "Fire Ant didn't just compromise systems. It compromised the trust layer those systems depend on."

The firm withheld the victim's identity and sector to protect the organization and connected networks, and said the pattern is most consistent with long-term espionage. Critical infrastructure networks were reached but appear to have been limited to reconnaissance. Cisco did not immediately comment.

The findings feed directly into an active regulatory push. CISA and allied agencies have issued repeated hardening guidance for network edge devices after the Salt Typhoon telecom intrusions, and operators covered by the EU's NIS2 directive face supply-chain and incident-reporting duties that extend to routers and authentication systems. Detecting this class of intrusion requires out-of-band verification that many organizations do not yet perform.

Sygnia published file hashes and YARA rules for the malware and persistence components.

Gunra Ransomware Builds a New Attack Network Through RaaS

11 August 2026 at 07:01

Gunra ransomware

Gunra ransomware has expanded its operations through a structured ransomware-as-a-service (RaaS) affiliate program, prompting the FBI, CISA and other agencies to issue a joint advisory warning organizations about the threat. The Gunra ransomware variant uses a double-extortion model, encrypting victim data while threatening to publish stolen information on a dedicated leak site if ransom demands are not met. The FBI first observed Gunra in April 2025 as a double-extortion ransomware variant derived from leaked Conti ransomware source code.

Gunra Ransomware Shifts to Affiliate Model

By early 2026, the group had expanded through a formal ransomware-as-a-service affiliate program advertised on dark web forums. The program provides affiliates with a management panel, configurable ransomware builder, cross-platform locker payloads and affiliate documentation. The FBI also observed Gunra operating under new branding aliases, including Golden Community, while recruiting penetration testers and ethical hackers as initial access brokers. Gunra initially focused on Windows environments before introducing a Linux variant and moving toward broader cross-platform targeting. Victims observed on the group’s dedicated leak site include organizations across the Americas, Europe, the Middle East, Africa and the Asia-Pacific. Targeted sectors include healthcare and public health, financial services and insurance, critical manufacturing, transportation, government services, utilities, academia, media and communications, retail, and professional and nonprofit services. Gunra ransomware

VPN Vulnerabilities Used for Initial Access

According to the advisory, Gunra actors primarily gained initial access by exploiting known vulnerabilities in internet-facing devices, including firewall and VPN gateways. The FBI observed exploitation of CVE-2024-55591 and CVE-2025-24472, authentication bypass vulnerabilities affecting specific FortiOS and FortiProxy versions. The Republic of Korea’s National Police Agency also observed Gunra actors exploiting credential exposure and SSH access control weaknesses in internet-facing VPN gateways to obtain unauthorized remote access. After gaining access, attackers used tools including Impacket utilities to move laterally through victim networks using SMB. In one case, actors compromised an SSL-VPN appliance using default credentials where account lockout controls were absent. They later used stolen session information to access internal virtual desktop infrastructure and move through systems including Active Directory servers and IT personnel workstations.

Data Theft Precedes Encryption

The double-extortion ransomware operation involves stealing sensitive information before encrypting systems. The FBI observed Gunra actors collecting business-critical documents, databases, personally identifiable information, and internal email communications. In at least one case, the actors used a malicious executable called main.exe to exfiltrate data from Microsoft OneDrive and SharePoint. Compressed archives containing sensitive information were also transferred to the Mega file-sharing service, with the volume of exfiltrated data reaching tens of terabytes. For encryption, Gunra uses ChaCha20 and RSA-4096 algorithms and has been observed using the .ENCRT extension for encrypted files. A documented sample from July 2025 used the .CRYPT extension. The ransomware also uses Windows Management Instrumentation to delete volume shadow copies before encryption, while one victim had backup and archived data deleted from both primary and disaster recovery infrastructure.

Agencies Urge Patching and Network Segmentation

The authoring agencies recommend that organizations prioritize patching known exploited vulnerabilities in internet-facing systems, including VPN gateways and RDP-exposed infrastructure. They also advise implementing and testing offline, immutable backups stored in physically separate and segmented locations. Network segmentation is another key recommendation, intended to restrict lateral movement and limit the spread of ransomware between systems. The agencies also recommend reviewing domain controllers, servers, workstations and Active Directory environments for unrecognized accounts, auditing administrative privileges, requiring MFA where possible and testing security controls against the Gunra techniques mapped to the MITRE ATT&CK framework. The joint advisory was published August 10, 2026, as part of the ongoing #StopRansomware initiative.

What’s your data worth on the dark web? (Lock and Code S07E15)

27 July 2026 at 10:35

This week on the Lock and Code podcast…

Twenty years ago, a British mathematician named Clive Humby popularized a phrase that came to describe data’s relationship with the entire global economy: “Data is the new oil.”

Pithy as the phrase sounds, it is undeniably true.

Data steers decisions at businesses of every size. Data created entirely new industries built around its capture. And, for a select number of companies, data has produced billions—if not trillions—of dollars in value.

So how is it that, on the dark web, your stolen identity can be purchased for just 95 cents?

That’s what a Malwarebytes researcher found last month after spending 48 hours inside the dark web to investigate cybercrime. Across a variety of forums and directories, he found subscription plans for malware that steals information once implanted on a device. He found guides for deploying social engineering scams. He found people selling their services to build fake websites that trick people into handing over their usernames and passwords. And he found one of the dark web’s most traded commodities—personal data, packaged together about individual people, to help a cybercriminal commit identity fraud.

These packages are called “fullz.” For victims in the United States, a fullz contains a full name, Social Security Number, date of birth, address, and other personal details. That is enough, on its own, for a cybercriminal to potentially open a bogus line of credit, file a fake tax return, access financial accounts, or obtain medical services under someone else’s name.

As we wrote on Malwarebytes Labs:

“For less than the cost of a cup of coffee, a cybercriminal can buy enough information to devastate someone’s financial life.”

It’s the kind of risk that could scare anyone, especially considering the scale behind it. In just the first six months of 2026, Malwarebytes found more than 7,500 compromised data sets on the dark web containing more than 8.4 billion records.

And yet, even today, cybersecurity professionals still get asked why anyone should bother protecting their data.

The public, understandably, are exhausted. With data breaches happening every week—if not every day—cybersecurity can start to feel pointless. With young people unable to build financial security, they start believing that they have nothing worth stealing. And with Big Tech already collecting our every movement, behavior, click, and concern, people understandably feel powerless to fight any kind of data abuse, be it corporate or criminal.

So today’s episode approaches the question from a different direction. This isn’t about why you should protect yourself—plenty of company websites will tell you that, and most of them rely on fear. This is about why hackers want your data in the first place.

Today, on the Lock and Code podcast, host David Ruiz explains how cybercriminals turn a single repeated password into account takeover, how a screenshot of your house from Google Maps became a tool in extortion emails, and why the most benign information about you—an address, an age, one public photo—is often the most useful data a stranger can buy.

Tune in today to listen to the full episode.

Harrowing story of an identity theft victim.

Yes, the person made a mistake—they gave the scammer a two-factor authentication code that allowed the scammer to take over their email address. But the real story here is how, for many of us, the security of most of our accounts hangs on the security of our email accounts.
