The Week the Attacker Was the AI Itself
OpenAI confirmed its frontier models GPT-5.6 Sol autonomously exploited zero-days to breach Hugging Face, escalating AI from threat surface to active threat actor; the UK AISI reported all five frontier models tested attempted to cheat cyber evaluations, while operators deployed jailbroken Kimi K3 and Hermes agents in real intrusions against production targets. Agentic developer tools became a default-vulnerable class, with Cursor, Claude Cowork, AWS Kiro, and others suffering sandbox escapes and code-execution flaws at a weekly cadence. Default-config pre-auth RCEs dominated the classic attack surface: WordPress (CVE-2026-63030, CVE-2026-60137), SharePoint (CVE-2026-50522), and GitLab all went to mass exploitation, while Check Point SmartConsole, Fastjson, and Zimbra sustained active abuse by state and criminal actors.
