AI Cryptanalysis Is Real, and Verification Is the Bottleneck

Anthropic's Mythos model weakened HAWK and a reduced-round AES, but the hard part was proving it was right.

No, an AI Did Not Break AES

Claude found real weaknesses in reduced-round ciphers and a NIST candidate — but the story is cost curves and verification, not broken crypto.
