- Anthropic's Claude Mythos Preview found weaknesses in real cryptographic algorithms, including an improved attack on HAWK — a post-quantum signature scheme humans had scrutinized for two-plus years — cracked in ~60 hours at about $100K of API cost, plus a faster attack on round-reduced AES. Anthropic stresses nothing in production is affected today, but it's a signal about AI cryptanalysis (Anthropic, The Hacker News). Bruce Schneier's write-up frames the broader benchmark question of how well LLMs can actually do cryptanalysis (Schneier). · AI & Model Security
