Frontier AI Models Cross Critical Threshold for Autonomous Cyber Attacks
Anthropic's Claude Mythos and OpenAI's GPT-5.5 became the first AI models to successfully execute multi-step cyber attacks, achieving 2-3 out of 10 complete domain takeovers in controlled simulations. The UK AI Security Institute reports offensive cyber capabilities are now doubling every four months, marking AI's transition from defensive tool to potential offensive weapon.
This represents a fundamental shift in AI threat models, with clear implications for national security policy and enterprise risk management as autonomous cyber weapons become feasible.
