The China-nexus cyber espionage group tracked as Armory Castle (previously UNC5221 or Warp Panda) exploited a newly disclosed security flaw in BeyondTrust Remote Support (formerly Bomgar) as a zero-day in late August 2026. The vulnerability, tracked as CVE-2026-102764 (CVSS score: 9.3), is a case of improper origin validation in an internal messaging component that could be exploited by a remote attacker to perform file operations on an affected appliance. "The vulnerability exists within internal components of Remote Support," BeyondTrust said in a Thursday alert. "The components did not adequately validate the origin of the messages it received. Under the right conditions, this could be used to perform file operations on the appliance." Patches for the flaw have been pushed to all Remote Support SaaS customers as of October 9, 2026. Self-hosted customers of Remote Support running versions from 24.3.1 through 26.2.3 are advised to manually update to BT26-0...

Candiru, an Israeli maker of spyware sold to governments, infected devices at the news network Al Jazeera through ordinary online ads, in attacks that needed no click or other action from the user, researchers at  the Citizen Lab  said Thursday. The hidden attack code ran the moment an ad loaded on the screen, and in some cases the ad loaded out of sight, in the background. The Citizen Lab, a research group at the University of Toronto, said this is the first public, technical confirmation that mercenary spyware, meaning hacking tools sold to governments, has reached real devices through targeted ads. The method had been described before from leaked company documents, but not shown in a live attack. The researchers recovered the spyware itself from one device, but not the exploit that breaks into the browser or app to install it. That first break-in step is described from how the attack was set up, not from captured code. How the Attack Worked The ads were placed by...

The threat actor known as Silent Lynx has been attributed to a fresh set of attacks targeting government organizations across the Commonwealth of Independent States (CIS). The activity, observed from June 2025 through August 2026, involves four different infection chains that make use of macro-enabled documents, PS2EXE downloaders, GitHub-hosted PowerShell, and crafted WinRAR archives exploiting CVE-2025-8088 . The attacks lead to the deployment of custom reverse shells like FoalShell, Chvost, Laplas, and PickleShell that facilitate interactive remote access to compromised hosts, according to Cisco Talos and Recorded Future Insikt Group, which are tracking the campaign under the monikers UAT-6275 and TAG-193.  "UAT-6275's targeting is concentrated in Central Asia, and the wider CIS region," security researcher Ashley Shen said . "Across the reviewed campaigns, observed victims and lure themes span nine countries: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenist...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added five security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, following their abuse by a China-linked threat actor known as Flax Typhoon. The vulnerabilities in question are listed below - CVE-2015-3306 (CVSS score: 10.0) - An improper access control vulnerability in ProFTPD that could allow remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands. CVE-2021-3199 (CVSS score: 9.8) - A path traversal vulnerability in ONLYOFFICE Docs that can occur when JSON Web Token (JWT) is used, via a "/.." sequence in an image upload parameter and could allow for remote code execution. CVE-2023-22894 (CVSS score: 7.2) - A cleartext storage of sensitive information vulnerability in Strapi that could allow an attacker with access to the admin panel to discover sensitive user details via the query filter. CVE-2016-3081 (CVSS score: 8.1) - A...

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...
