Anthropic has used Claude Mythos to develop a practically inapplicable but academically relevant attack on AES variants and an improved attack on the post-quantum candidate Hawk.
Mythos demonstrates that AI-driven exploit automation drastically reduces time-to-exploit — but the real problem lies in the gaps in existing vulnerability management playbooks.
As dwell time approaches zero, a paradigm shift from detection and prevention toward preemptive resilience with recovery as a design principle becomes necessary.
Anthropic releases its AI model Mythos with built-in restrictions for cybersecurity and biotech use, while a separate government program continues to enable unrestricted access for security testing.
After weeks of exclusion, the EU now gains access to Anthropic’s Mythos hacking AI model, while the Commission works on a formal action plan for such systems.
