Anthropic's restricted Claude Mythos 5 shares its architecture with Fable 5 but ships without cybersecurity guardrails, deployed via Project Glasswing with the US government.
Anthropic's Frontier Red Team mapped 13,873 real attacks to MITRE ATT&CK — and found the framework has no ID for the autonomous agentic behavior defining the highest-risk actors.
Anthropic brings Claude Mythos Preview to ~150 new orgs in 15+ countries covering power, water, healthcare and more, plus launches Claude Security in public beta.
Anthropic's Project Glasswing used Claude Mythos Preview to find over 10,000 high or critical vulnerabilities across critical software in just one month.
