Claude Mythos Broke HAWK-256 and Sped Up an AES-128 Attack — Here's Why Nobody's Cheering
Anthropic says its Claude Mythos Preview model found a mathematical weakness in HAWK, a NIST post-quantum candidate, and sped up an attack against reduced-round AES-128. A cryptographer from NIST's own process confirmed the math within the hour — but nobody outside Anthropic has independently verified the full attack yet.
