July 30: AI Breaks Cryptography — Mythos Discovers HAWK and AES Flaws

One new research article published: Anthropic's Claude Mythos Preview autonomously discovers mathematical flaws in the HAWK post-quantum signature scheme and a novel Möbius Bridge attack on 7-round AES, marking the first time AI has found algorithmic (not just implementation) cryptographic weaknesses.

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.
