AI Cyberoffense Capabilities Doubling Every Four Months, Clearing Advanced Attack Simulations
The UK AI Security Institute reports that both Anthropic's Claude Mythos and OpenAI's GPT-5.5 successfully completed a sophisticated 32-step corporate cyberattack simulation called 'The Last Ones.' This represents a dramatic acceleration in AI offensive cyber capabilities, with doubling times now at just four months compared to previous estimates.
This exponential growth in AI cyberoffense creates urgent national security implications and may trigger accelerated defensive AI development and regulatory responses across critical infrastructure sectors.
