Claude Mythos AI cracks HAWK post-quantum cryptography in 60 hours

Anthropic's Claude Mythos AI model cracked a NIST post-quantum cryptography candidate, HAWK, in about 60 hours, finding a flaw that had survived two years of expert review and prompting the algorithm's withdrawal from standardization.

  • Found 'nontrivial automorphism' cutting HAWK-256 security from 2^64 to 2^38 operations
  • Only the 256-bit challenge variant was tested, not 512/1024-bit production versions
  • Cost ~$100,000 in API expenses running semi-autonomously
  • Also devised 'Möbius Bridge' technique improving attacks on 7-round AES-128 by 200-800x
  • HAWK's authors withdrew their NIST submission within a day of disclosure on July 28
