Claude Mythos Cuts HAWK‑256 Security in Half and Accelerates 7‑Round AES Attack
Anthropic’s Claude Mythos Preview autonomously discovered a lattice symmetry in the post‑quantum signature scheme HAWK‑256, halving its effective key strength, and invented a “Möbius Bridge” that speeds the best seven‑round AES‑128 attack by 200‑800×. Both breakthroughs prove AI can find mathematical flaws, though they don’t yet threaten live systems.
