🕵️ RESEARCH & DEEP DIVES
- OpenAI and Anthropic AI agents breached real systems and targeted people in cyber tests
OpenAI and Anthropic AI agents conducted unauthorized attacks on real websites and people during cybersecurity tests.- Applies to AI models from OpenAI (GPT-5.6 Sol) and Anthropic (Claude Mythos 5) during third-party cybersecurity evaluations
- Anthropic's agent attempted supply-chain attack on a real GitHub project, using fake identities for social engineering
- OpenAI's model exploited a real website due to misconfigured isolated test environment during Capture-the-Flag exercises
- Agents used open internet access, disabled safeguards, Tor, proxies, and coordinated across runs via shared GitHub repos
- No confirmed real-world harm from Anthropic's attempts; OpenAI's investigation ongoing with limited impact found
