Researchers have identified a recent cyber espionage campaign by a China-linked threat actor dubbed "UNK_SweetSpecter," which aims to harvest generative artificial intelligence (AI) secrets from experts in the United States. The threat actor targets AI experts using a remote access trojan (RAT) malware called SugarGh0st.  SugarGh0st infiltrates the systems of a highly selective list of AI experts from different verticals such as tech companies, government agencies and academic institutions. The SugarGh0st RAT was originally reported in November 2023 but was observed in only a limited number of campaigns. It is a custom variant of the Gh0st RAT, a tool that was first publicly attributed to a Chinese threat group in 2008. Researchers suspect that the threat actor UNK_SweetSpecter is likely of Chinese origin.

Spear-Phishing SugarGh0st Campaign Targets AI Experts

Proofpoint researchers discovered that the targets of this campaign were all connected to a leading US-based AI organization and were lured with distinct AI-themed emails. The infection chain began with a seemingly innocuous email from a free account, claiming to seek technical assistance with an AI tool. The attached zip file contained a shortcut file (LNK) that deployed a JavaScript dropper upon access. This dropper included a decoy document, an ActiveX tool for sideloading, and an encrypted binary, all encoded in base64. The infection chain ended with SugarGh0st RAT being deployed on the victim's system and communication being established with the attacker's command and control server. Analysis of the attack stages revealed that the group had shifted their C2 communications from an earlier domain to a new one, indicating their detection evasion motives. While the malware itself is relatively unsophisticated in it's attack chain, the targeted nature of AI the campaign makes it significant, the researchers noted. The SugarGh0st RAT was previously used in targeted campaigns in Central and East Asia.

Potential Motivations, Attribution and Context

Although direct attribution to a specific nation-state is challenging, researchers concluded the presence of Chinese language artifacts and the precise targeting of AI experts suggest a possible link to China-linked threat actors. The campaign also coincides with the U.S. government's efforts to restrict Chinese access to generative AI technologies. The new regulations established by the Biden administration would likely restrict the export of AI models, and their data to countries it deemed hostile to U.S. interests, such as Russia, China, North Korea and Iran. The Chinese Embassy labeled the action as economic coercion and unilateral bullying. Earlier in February, Microsoft reported observing Chinese, Russian, North Korean and Iranian threat actors' attempting to leverage AI tools from big tech AI companies like OpenAI for their campaigns. The report indicated that Chinese threat actors used AI tools to boost their technical prowess such as the development of tools and phishing content, while the Russian threat actors were observed researching  satellite and radar technologies possibly related to the war in Ukraine. With the regulatory efforts aimed at restricting proprietary/closed-source AI models, researchers theorize that this campaign is likely an attempt by a China-affiliated actor to harvest generative AI secrets via cyber theft before the policies are enacted.

Researchers recently uncovered two new backdoors implanted within the infrastructure of a European Ministry of Foreign Affairs (MFA) and its diplomatic missions. Slovakian cybersecurity firm ESET who found these two new backdoors dubbed “LunarWeb” and “LunarMail,” attributed them to the Turla cyberespionage group believed to be aligned with Russian interests. Turla has operated since at least 2004, possibly starting in the late 1990s. Linked to the Russian FSB, Turla primarily targets high-profile entities like governments and diplomatic organizations in Europe, Central Asia and the Middle East. Notably, they have breached significant organizations such as the US Department of Defense in 2008 and the Swiss defense company RUAG in 2014. Researchers believe the Lunar toolset that has been used since at least 2020 is an addition to the arsenal of Russia-aligned cyberespionage group Turla based on the similarities between the tools’ tactics, techniques, and procedures (TTPs) and past activities.

LunarWeb Backd: Used to Navigate the Digital Terrain

LunarWeb backdoor stealthily infiltrates servers, establishing its foothold within the targeted infrastructure. Operating covertly, it communicates via HTTP(S) while mirroring legitimate traffic patterns to obfuscate its presence. Concealment is key in LunarWeb's playbook. For this the backdoor used steganography technique. This backdoor covertly embeds commands within innocuous images, effectively evading detection mechanisms. LunarWeb's loader, aptly named LunarLoader, showcases remarkable versatility, the researchers noted. Whether masquerading as trojanized open-source software or operating in standalone form, this entry point demonstrates the adaptability of the adversary's tactics.

LunarMail: Used to Infiltrate Individual Workstations

LunarMail takes a different approach as compared to LunarWeb. It embeds itself within Outlook workstations. Leveraging the familiar environment of email communications, this backdoor carries out its spying activities remaining hidden amidst the daily deluge of digital correspondence that its victims receive on their workstations. [caption id="attachment_68881" align="aligncenter" width="1024"] LunarMail Operation (credit: ESET)[/caption] On first run, the LunarMail backdoor collects information on the environment variables, and email addresses of all outgoing email messages. It then communicates with the command and control server through the  Outlook Messaging API to receive further instructions. LunarMail is capable of writing files, setting email addresses for C&C communication, create arbitrary processes and execute them, take screenshots and more. Similar to its counterpart, LunarMail harnesses the power of steganography albeit within the confines of email attachments. By concealing commands within image files, it perpetuates its covert communication channels undetected. LunarMail's integration with Outlook extends beyond mere infiltration. It manipulates email attachments, seamlessly embedding encrypted payloads within image files or PDF documents which facilitates unsuspicious data exfiltration.

Initial Access and Discovery

The initial access vectors of the Turla hackers, though not definitively confirmed, point towards the exploitation of vulnerabilities or spearphishing campaigns. The abuse of Zabbix network monitoring software is also a potential avenue of compromise, the researchers said. The compromised entities were primarily affiliated with a European MFA, which meant the intrusion was of a strategic nature. The investigation first began with the detection of a loader decrypting and running a payload from an external file, on an unidentified server. This was a previously unknown backdoor, which the researchers named LunarWeb. A similar attack chain with LunarWeb was then found deployed at a diplomatic institution of a European MFA but with a second backdoor – named LunarMail. In another attack, researchers spotted simultaneous deployments of a chain with LunarWeb at three diplomatic institutions of this MFA in the Middle East, occurring within minutes of each other. “The attacker probably had prior access to the domain controller of the MFA and utilized it for lateral movement to machines of related institutions in the same network,” the researchers noted. The threat actors displayed varying degrees of sophistication in the compromises. The coding errors and different coding styles used to develop the backdoors suggested that “multiple individuals were likely involved in the development and operation of these tools.”

Russian State Hackers Biggest Cyber Threat

Recently, Google-owned Mandiant in a detailed report stated with “high confidence” that Russian state-sponsored cyber threat activity poses the greatest risk to elections in regions with Russian interest including the European Union, the United Kingdom and the United States. Russia’s approach to election interference is multifaceted, blending cyber intrusion activities with information operations aimed at influencing public perceptions and sowing discord. Russian state-aligned cyber threat actors target election-related infrastructure for various reasons including applying pressure on foreign governments, amplifying issues aligned with Russia’s national interests, and retaliating against perceived adversaries. Groups like APT28 and UNC4057 conduct cyber espionage and information operations to achieve these objectives, Mandiant said.

A state or state-sponsored actor orchestrated the "sophisticated" cyberattacks against the British Columbia government networks, revealed the head of B.C.’s public service on Friday. Shannon Salter, deputy minister to the premier, disclosed to the press that the threat actor made three separate attempts over the past month to breach government systems and that the government was aware of the breach, at the time, before finally making it public on May 8. Premier David Eby first announced that multiple cybersecurity incidents were observed on government networks on Wednesday, adding that the Canadian Centre for Cyber Security (CCCS) and other agencies were involved in the investigation. Salter in her Friday technical briefing refrained from confirming if the hack was related to last month’s security breach of Microsoft’s systems, which was attributed to Russian state-backed hackers and resulted in the disclosure of email correspondence between U.S. government agencies. However, she reiterated Eby's comments that there's no evidence suggesting sensitive personal information was compromised.

British Columbia Cyberattacks' Timeline

The B.C. government first detected a potential cyberattack on April 10. Government security experts initiated an investigation and confirmed the cyberattack on April 11. The incident was then reported to the Canadian Centre for Cyber Security, a federal agency, which engaged Microsoft’s Diagnostics and Recovery Toolset (DaRT) due to the sophistication of the attack, according to Salter. Premier David Eby was briefed about the cyberattack on April 17. On April 29, government cybersecurity experts discovered evidence of another hacking attempt by the same “threat actor,” Salter said. The same day, provincial employees were instructed to immediately change their passwords to 14 characters long. B.C.’s Office of the Chief Information Officer (OCIO) described it as part of the government's routine security updates. Considering the ongoing nature of the investigation, the OCIO did not confirm if the password reset was actually linked to the British Columbia  government cyberattack but said, "Our office has been in contact with government about these incidents, and that they have committed to keeping us informed as more information and analysis becomes available."

Another cyberattack was identified on May 6, with Salter saying the same threat actor was responsible for all three incidents.

The cyberattacks were not disclosed to the public until Wednesday late evening when people were busy watching an ice hockey game, prompting accusations from B.C. United MLAs that the government was attempting to conceal the attack.

“How much sensitive personal information was compromised, and why did the premier wait eight days to issue a discreet statement during a Canucks game to disclose this very serious breach to British Columbians?”the Opposition MLA Todd Stone asked. Salter clarified that the cybersecurity centre advised against public disclosure to prevent other hackers from exploiting vulnerabilities in government networks. She revealed three separate cybersecurity incidents, all involving efforts by the hackers to conceal their activities. Following a briefing of the B.C. NDP cabinet on May 8, the cyber centre concurred that the public could be notified. Salter said that over 40 terabytes of data was being analyzed but she did not specify if the hackers targeted specific areas of government records such as health data, auto insurance or social services. The province stores the personal data of millions of British Columbians, including social insurance numbers, addresses and phone numbers. Public Safety Minister and Solicitor General Mike Farnworth told reporters Friday that no ransom demands were received, making the motivation behind the multiple cyberattacks unclear.

Farnworth said that the CCCS believes a state-sponsored actor is behind the attack based on the sophistication of the attempted breaches.

"Being able to do what we are seeing, and covering up their tracks, is the hallmarks of a state actor or a state-sponsored actor." - Farnworth

Government sources told CTV News that various government ministries and agencies, and their respective websites, networks and servers, face approximately 1.5 billion “unauthorized access” or hacking attempts daily. The number has increased over the last few years and the reason why the province budgets millions of dollars per year to cybersecurity. Salter confirmed the government spends more than $25 million a year to fortify its defenses and added that previous investments in B.C.'s cybersecurity infrastructure helped detect the multiple attacks last month. Microsoft last month alerted several U.S. federal agencies that Russia-backed hackers might have pilfered emails sent by the company to those agencies, including sensitive information like usernames and passwords. However, Salter did not confirm if Russian-backed hackers are associated with the B.C. security breach.

Dell has issued a warning to its customers regarding a data breach following claims by a threat actor of pilfering information for roughly 49 million customers. In an email sent to customers, the computer manufacturer disclosed that a Dell portal containing customer data associated with purchases had been compromised. "We are presently investigating an incident involving a Dell portal, housing a database containing limited types of customer information linked to Dell purchases," stated a Dell data breach notification. Dell clarified that the accessed information encompassed:

• Names
• Physical addresses
• Dell hardware and order details, comprising service tags, item descriptions, order dates, and relevant warranty information

The company said the stolen data did not encompass financial or payment data, email addresses or phone numbers. Dell assured customers that they are collaborating with law enforcement and a third-party forensics firm to probe the matter. [caption id="attachment_67595" align="aligncenter" width="687"] Dell data breach notification[/caption] Dell Technologies is a publicly traded company that operates in 180 countries and is headquartered in Round Rock, Texas. Dell is the third-largest personal computer vendor in the world by unit sales, behind Lenovo and HP and serves more than 10 million small and medium-sized businesses and receives 500 million annual eCommerce visits. The tech giant generated a revenue of $102.3 billion in 2023 and has over 500,000 commercial customers and 2,500 enterprise accounts.

Dell Data Breach Set Appeared on Dark Web

Despite Dell's reassurances, the breach data was purportedly put up for sale on an underground hacker forum by a threat actor named “Menelik” on April 28. The threat actor claimed this data set contained an up-to-date details of registered Dell servers including vital personal and company information such as full names, addresses, cities, provinces, postal codes, countries, unique 7-digit service tags of systems, system shipment dates (warranty start), warranty plans, serial numbers (for monitors), Dell customer numbers and Dell order numbers. The threat actor asserted that he was the sole possessor of this data that entailed approximately 7 million records of individual/personal purchases, while 11 million belong to consumer segment companies. The remaining data pertained to enterprise, partners, schools or unidentified entities. The threat actor also highlighted the top five countries with the most systems represented in the database, which included the United States, China, India, Australia and Canada. The data, claimed to be sourced from Dell and containing 49 million customers and other systems details between 2017 and 2024, aligned with the details outlined in Dell's breach notification. However, The Cyber Express could not confirm if the two data sets are the same as Dell did not immediately respond to our request for confirmation. Although the sale of the database appears to have ceased, the possibility of further exploitation remains. Although Dell refrained from disclosing the specific impact of the breach, it remains vigilant about potential risks associated with the stolen information. While the compromised data lacks email addresses, threat actors could exploit it for targeted phishing and smishing attacks against Dell customers. They could contact Dell customers as fake customer service executives and lead them into downloading malware or infostealers as is seen in many previous campaigns. Dell advises customers to exercise caution regarding any communications purportedly from Dell, especially those urging software installations, password changes or other risky actions and encourages customers to verify the legitimacy of such communications directly with Dell.

With more than 2 billion voters ready to cast a vote this year across 60 plus nations -including the U.S., U.K. and India - Russian state hackers are posing the biggest cyber threat to election security, researchers said. Google-owned Mandiant in a detailed report stated with “high confidence” that Russian state-sponsored cyber threat activity poses the greatest risk to elections in regions with Russian interest.

“Multiple Russian groups have targeted past elections in the U.S., France, and Ukraine, and these groups have continued to demonstrate the capability and intent to target elections both directly and indirectly,” Mandiant said.

Why Russia is the Biggest Cyber Threat to Election Security

Russia's approach to election interference is multifaceted, blending cyber intrusion activities with information operations aimed at influencing public perceptions and sowing discord. State-sponsored cyber threat actors, such as APT44, better known as the cyber sabotage unit Sandworm, and APT28 have a history of targeting elections in the U.S., and Europe. These actors employ hybrid operations, combining cyber espionage with hack-and-leak tactics to achieve their objectives. The 2016 U.S. presidential election is a prime example of Russia's cyber interference capabilities, as per Mandiant. APT28, linked to Russia intelligence unit - the GRU, compromised Democratic Party organizations and orchestrated a leak campaign to influence the election's outcome. Similarly, in Ukraine, APT44 conducted disruptive cyber operations during the 2014 presidential election, aiming to undermine trust in the electoral process. Jamie Collier, Mandiant senior threat intelligence advisor said, “One group to watch out for is UNC5101 that has conducted notable hybrid operations in the past.” Mandiant reports UNC5101 engaging in cyber espionage against political targets across Europe, Palestinian Territories, and the U.S. The actor has also used spoofed Ukrainian government domains to spread false narratives directly to government employees' inboxes. Before Russia's 2023 and 2024 elections, UNC5101 registered domains related to opposition figures like Alexei Navalny and conducted likely information operations to deceive voters. Russian state-aligned cyber threat actors target election-related infrastructure for various reasons including applying pressure on foreign governments, amplifying issues aligned with Russia's national interests, and retaliating against perceived adversaries. Groups like APT28 and UNC4057 conduct cyber espionage and information operations to achieve these objectives, Mandiant said.

Beijing’s Interest in Information Operations

Collier noted that state threats to elections are far more than just a Russia problem.

“For instance, we have seen pro-China information operations campaigns carry out election-related activity in the US, Taiwan, and Hong Kong,” Collier said.

China's approach to election cybersecurity focuses on intelligence collection and influence operations that promote narratives favorable to the Chinese Communist Party (CCP). State-sponsored actors like TEMP.Hex have targeted elections in Taiwan, using cyberespionage to gather critical information and using information operations to shape public discourse, Mandiant’s analysis found. In the lead-up to Taiwan's 2024 presidential election, Chinese threat actors intensified cyber espionage activities, targeting government, technology, and media organizations. Concurrently, pro-PRC information operations sought to discredit candidates perceived as unfriendly to China, using fabricated leaks and disinformation campaigns to sway public opinion, which even the Taiwanese government confirmed.

Watch-Out for Iran’s Espionage and Influence Campaigns

Iranian state hackers are another group of threat actors to keep an eye on for their cyber espionage and influence campaigns, Mandiant noted.

“[Irans’s] campaigns will rise as elections approach in key nations of interest to the Islamic Republic, such as counterparts in the currently stalled nuclear negotiations, and countries offering support to Israel during current fighting in Gaza,” Mandiant said.

During the 2020 U.S. presidential election, Iran attempted to compromise state voter registration websites and disseminate false information. The U.S. Department of Justice charged two Iranian nationals in 2021 for their involvement in this campaign. Pro-Iranian influence campaigns, including Liberty Front Press and Roaming Mayfly, target global audiences with anti-U.S. and anti-Israeli propaganda, amplifying partisan divisions and fostering distrust in democracies, Mandiant said.

Diverse Targets Multiple Vectors

Securing elections requires protecting not only voting machines and voter registries but also a wide range of entities involved in the electoral process. Political parties, news media, and social media platforms are frequent targets of cyber operations, which also comes under the attack surface of elections. [caption id="attachment_65433" align="aligncenter" width="551"] Credit: Mandiant[/caption] Cyber threat actors are increasingly employing hybrid operations, combining multiple tactics to amplify their impact. Examples from past elections, such as the Ukrainian presidential election in 2014, illustrate how they are using a combination of cyber intrusions, data leaks, and DDoS attacks to disrupt electoral processes. Owing to this Mandiant detailed likely threat vectors that could be used in the upcoming election season: [caption id="attachment_65432" align="aligncenter" width="819"] Credit: Mandiant[/caption] The threats posed by Russian, Chinese, and Iranian state actors to election cybersecurity are complex and multifaceted. By understanding the tactics and objectives of these actors, election organizations can develop effective mitigation strategies to safeguard democratic processes. However, addressing these threats requires a concerted effort involving international cooperation and a commitment to upholding the integrity of democratic elections worldwide. In-line with this, the U.S. agencies recently released guidance to defending the integrity of democratic processes. The guidance extensively details common tactics seen in foreign malign influence operations, offering real-world instances and suggesting possible countermeasures for stakeholders in election infrastructure. Though many of these tactics aren't new, the widespread use of generative artificial intelligence (AI) has notably amplified adversaries' ability to produce and spread persuasive malicious content, the guidance said.
