CryptanalysisBench: Frontier LLMs Are Now Finding Novel Cryptographic Attacks
A new academic-Anthropic benchmark shows frontier models breaking real cryptographic tasks — and one model surfaced a genuine design flaw and a proof error in NIST-track candidates, not just textbook exercises.

Claude Mythos Finds Real Math Flaws in HAWK and Weakened AES
Anthropic researchers used a specialised Claude model to discover a genuine cryptanalytic improvement against the post-quantum HAWK signature scheme and a reduced-round AES-128 variant — theoretical results, but a notable data point for AI-assisted cryptanalysis.
