Anthropic's Mythos Preview Breaks Cryptography: HAWK Post-Quantum Attack, AES Möbius Bridge, and the Rise of AI Cryptanalysis
Anthropic's Claude Mythos Preview autonomously discovered improved attacks on the HAWK post-quantum digital signature scheme (cutting effective key strength in half) and a novel Möbius Bridge attack on 7-round AES (200-800× faster than prior best). Covers the multi-agent discovery process, CryptanalysisBench benchmark, additional breaks on LEA and Serpent, and what AI-driven cryptanalysis means for the future of digital security.
