The U.S. Federal Bureau of Investigation (FBI) and Department of Justice (DoJ) have announced the disruption of malicious tools used by a China-linked advanced persistent threat group known as Flax Typhoon. To that end, the agencies seized several domains and blocked access to platforms that were used to scan, and in some cases infiltrate, U.S. critical infrastructure. The list of seized domains is as follows - c0cc[.]cc 98aiblog[.]com 98aicai[.]com 98aicode[.]com outlook3650[.]com youtubecard[.]com linkedinns[.]net Flax Typhoon , also tracked as Ethereal Panda and RedJuliett, is associated with Integrity Technology Group, a Beijing-based company that contracts with the Chinese government. It was previously attributed to a botnet called Raptor Train that comprised thousands of compromised small office/home office (SOHO) and IoT devices. It was taken down following a U.S. court-authorized operation in September 2024. "These state-sponsored hackers co...

Hackers tied to a Chinese cybersecurity company stole email from government organizations, law enforcement agencies, healthcare systems, and religious institutions in Southeast Asia, the FBI and agencies in 6 other countries said on October 8. The company, Integrity Technology Group , has been sanctioned by the U.S. and the UK. The hackers scanned websites for flaws using a tool containing more than 1,300 scripts, guessed passwords for Microsoft 365 and Exchange accounts, and copied mailboxes using tools designed to collect mail. The hackers have been breaking into networks since at least mid-January 2021, according to the agencies'  joint advisory . It describes the hacking in the present tense but provides no date for any theft and does not specify how many organizations were breached. The same hackers targeted U.S. government services, critical manufacturing, healthcare, and IT organizations, along with U.S. law enforcement, education, and religious groups. Organizations ...

The Russia-aligned threat actor known as UAC-0099 has been attributed to a previously undocumented .NET infostealer and remote access trojan (RAT) codenamed ASHVEIN . According to TrendAI, the malware has been put to use in attacks targeting Ukrainian government personnel. The cybersecurity company is tracking the cluster under the name Earth Sirrush (previously SHADOW-EARTH-065). ASHVEIN, which its developers internally refer to as "TelemetryBrowser," brings together credential theft, surveillance, and remote-control capabilities. Its functionality includes credential theft from Chrome and Firefox, GDI-based screenshot capture, file enumeration and retrieval, PowerShell remote shell execution, system fingerprinting, and encrypted command-and-control (C2) communications. "ASHVEIN also hides tasking inside invisible HTML elements," TrendAI said . "Some variants use a GitHub-based dead drop resolver as a fallback mechanism, while delivery methods inclu...

The U.S. State Department is offering up to $10 million for information leading to the identification or location of Zhang Yu, a Chinese national charged in the United States in connection with the 2021 Microsoft Exchange Server attacks known as HAFNIUM. The reward is for information leading to his identification or location, the news outlet  NTD reported  this week, citing a notice from the department's Rewards for Justice program. Zhang remains at large, U.S. authorities say, meaning he has not been arrested. The charges against him have not been tested in court. Rewards for Justice  is the State Department's national security rewards program. It says it has paid more than $250 million to over 125 people since 1984. Zhang is wanted for his alleged role in "malicious cyber activities against U.S. critical infrastructure," NTD quoted the notice as saying. The amount and that wording match an offer the program was already making  in January 2025 . That of...
