UK AI Security Institute Finds OpenAI's GPT-5.5 Can Autonomously Execute Complex Cyberattacks

AISI testing shows GPT-5.5 completed a 32-step corporate network attack simulation autonomously and solved a reverse-engineering challenge in 10 minutes that took a human 12 hours. The model achieved 71.4% pass rate on Expert-tier cybersecurity tasks, edging out Anthropic's Claude Mythos. Researchers also identified a universal jailbreak affecting all malicious queries tested.

Anthropic's Claude Mythos: The AI That Finds Zero-Day Flaws Raises Global Security Fears

Anthropic unveiled Claude Mythos, an AI model capable of finding and exploiting zero-day vulnerabilities in operating systems and browsers. The company refused public release, comparing it to giving burglars keys to every building. Forty US organizations are partnered in Project Glasswing to patch vulnerabilities before exploitation. Britain tested the model through its AI Security Institute, with ministers warning most businesses remain unprepared. Mozilla's test on Firefox found 10 times more flaws than conventional methods, though none were undetectable by humans. The Pentagon had previously deemed Anthropic a security risk before inviting it back into government cooperation.
