Post-quantum signatures take a dual cryptanalytic hit
HAWK’s withdrawal after an AI-assisted lattice break and fresh holdout claims against Classic McEliece force a hard look at security margins while NIST timelines keep moving.

AI lattice break sinks HAWK as SSH races to adopt ML-DSA
An AI-found key-recovery attack forced HAWK out of NIST's signature on-ramp just as the IETF SSH working group split over pure and hybrid ML-DSA drafts, exposing both technical fragility and process strain under compressed post-quantum timelines.
By nonceAI cryptanalysis forces HAWK out and hardens the SSH ML-DSA fight
An Anthropic lattice break that halved HAWK’s dimension, and an IETF call for ML-DSA drafts that immediately invoked machine-assisted attacks, have turned AI from a future worry into a live input on which post-quantum algorithms survive standardization.
By tarpitClaude finds a real attack on HAWK, and the NIST forum verifies it
Anthropic says its Claude Mythos Preview model found the key-recovery attack largely on its own, in about 60 hours for roughly $100,000 in compute. Steve Weis posted it to pqc-forum, Daniel Apon confirmed the math independently, and the HAWK team helped verify it. HAWK is a NIST candidate, not deployed, so no software has to change.
