The U.S. Department of Justice (DoJ) on Wednesday announced the disruption of two hacking platforms named QScan and QTRouter operated by Chinese threat actors to target critical infrastructure and other sensitive networks in the country. The activity has been attributed to a Chinese state-sponsored group known as QTFY, employed by Nanjing Xinjiuwei Network Technology Company (南京鑫玖维网络科技有限公司).  "Among the victims of QTFY computer intrusion activity are the National Aeronautics and Space Administration, Federal Reserve, Department of Energy, Department of Justice, Department of Health and Human Services, National Institutes of Health, and the U.S. Senate," DoJ said. Damon Rouse, a security researcher at Lumen Black Lotus Labs who has been tracking the activity for over the past 18 months, told The Hacker News that the digital quartermaster has been active since May 2018. Nanjing counts both China's Ministry of State Security (MSS) and the People's Liberation Army...

Cybersecurity researchers have discovered additional infrastructure and previously undocumented malware associated with Nimbus Manticore , an Iranian state-sponsored hacking group affiliated with the Islamic Revolutionary Guard Corps (IRGC). Group-IB, in a new analysis published today, described the cyber espionage actor as among the most active Iranian APT groups in 2026. Nimbus Manticore (aka GalaxyGato, Mirage Kitten, Screening Serpens, Smoke Sandstorm, Subtle Snail, and UNC1549) is assessed to be linked to Tortoiseshell (aka Imperial Kitten and Unyielding Wasp), which is part of the Charming Kitten (aka Eclipsed Wasp) cluster. Tortoiseshell is known to be active since at least July 2018, mainly targeting defense, aerospace, IT service providers, and military organizations in the Middle East and the U.S. Nimbus Manticore also has a history of orchestrating its own version of the Dream Job campaign to deliver malware under the pretext of job opportunity-themed social engine...

The U.S. Department of the Treasury has announced fresh sanctions on Iranian cyber actors as part of what it called an "unprecedented, whole-of-government, economic campaign" against the nation and its enablers. "We are launching an economic onslaught against Iran's financial connections around the globe. Our objective is to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone," said Secretary of the Treasury Scott Bessent. The action, codenamed Operation Economic Outcast, aims to cut the Iranian regime and the Islamic Revolutionary Guard Corps (IRGC) from the financial "lifelines" that support the "leading state sponsor of terror." To that end, the sanctions designate nearly 60 Iran-linked entities, individuals, and vessels across nuclear, missile, oil, and cyber networks, including the digital assets sector. Specifically, the sanctions take aim at a malicious cyber group affiliated with Iran...

Cybersecurity researchers have flagged a cyber espionage campaign targeting Myanmar that uses graduation ceremony invitation lures to deliver a Go backdoor called QUICAgent. The campaign, codenamed Operation QUICSILVER , has been found to target government and information technology sectors, per Seqrite Labs. The activity is assessed to be the work of a China-nexus threat actor with moderate confidence. It was first observed in April 2026, when the attack was observed delivering a file named "HolidayNotice.pdf.exe" along with a lure that was a fabricated Belgian–Myanmar public holiday calendar. Two subsequent artifacts, each detected in June and July 2026, make use of a Virtual Hard Disk (VHD) file that activates the infection chain. Present within the VHD file is a Windows Shortcut (LNK) that mimics a PDF document. Opening the document displays a decoy PDF to the victim, an official graduation ceremony invitation that's written in Burmese and purports to be from t...

Three distinct suspected Russian cyber espionage threat clusters have been observed leveraging legitimate authentication flows to single out individuals working in academia, aerospace and defense, governments, and think tanks across Europe, as well as academia and think tanks within the U.S. These clusters include UNC6293 , UNC7005 , and UNC5976 . "These clusters engage in persistent, adaptive phishing campaigns, using sophisticated social engineering tactics to compromise personal accounts across multiple platforms," Google Threat Intelligence Group (GTIG) researchers Gabby Roncone and Wesley Shields said in a report published today. UNC6293, first detailed by the tech giant and the Citizen Lab in June 2025, is assessed to be a sub-cluster of Ice Relic (formerly APT29), which is also tracked under the monikers Cozy Bear and Midnight Blizzard. The hacking crew was previously attributed to a campaign that abused a Google account feature called application specific pas...
