CyberSecurity Updates

Researchers at security firm Hacktron used Claude to build a working exploit for a vulnerability in an image-processing library, then chained it with a flaw in OpenAI’s sign-in system to take over employee ChatGPT and Codex accounts, and ultimately gained access to internal code repositories. The entry point was OpenAI’s community forum, community.openai.com, which runs on Discourse. Discourse’s built-in image checks didn’t support the HEIC/HEIF photo format, so uploads in that format were passed to…

Internet Systems Consortium (ISC) has released fresh security updates for BIND, the widely used open source DNS server software, resolving 14 vulnerabilities that could lead to denial-of-service (DoS) attacks. Seven are high-severity flaws that could be exploited to cause an unexpected program exit, memory exhaustion, named termination, and resource exhaustion, causing DoS conditions. The remotely exploitable bugs are tracked as CVE-2026-80274, CVE-2026-76163, CVE-2026-19666, CVE-2026-81563, CVE-2026-77692, CVE-2026-19667, and CVE-2026-81736. They can be triggered using mismatched NOQNAME…

More than 200,000 WordPress websites are potentially exposed to takeover attacks via two critical-severity vulnerabilities in The Events Calendar plugin. A highly popular plugin with over 600,000 active installations, The Events Calendar allows administrators to easily create and manage an events calendar on their websites. All plugin versions before 6.17.3.1 are affected by two code injection bugs that could lead to remote code execution (RCE), allowing attackers to take over sites, WordPress security firm Defiant…

Microsoft AI has published a draft “Humanist AI Code of Conduct” for its MAI Models, spelling out safety rules for offensive cyber capabilities, limits on autonomous AI agents, and a dedicated review track for cybersecurity and other specialized uses. According to the code of conduct, models are blocked from producing working exploit code, attack tooling, planning and targeting methodologies, intrusion procedures, evasion techniques, operational guidance, or other assistance that would enable or improve a cyberattack.…

Multiple espionage groups have been using a new exploit kit dubbed BlueMoon in seemingly opportunistic and rushed deployments, cybersecurity firm Proofpoint reports. The China-linked APT Violet Typhoon (also tracked as APT31, JungleBamboo, TA412, and Tide Castle) was the first to use it on August 28. Within days, several other Chinese threat actors started using it, but the activity might not be exclusive to China-aligned groups. “It is currently unknown how multiple distinct threat actors obtained…

Anthropic says Claude users in northern Yemen, territory controlled by Iran-backed Houthi rebels, tried to use the AI model to develop advanced missiles. AI is already transforming warfare from Ukraine to Gaza, and its use on a rugged and remote battlefield is likely to increase concerns about its rapid spread. Anthropic said the users of the accounts, which it blocked after identifying them, did not succeed in “fielding an operational device” but did carry out…
