Claude AI Just Cracked a Post-Quantum Test Scheme and Found a Faster 7-Round AES Attack
Anthropic's Claude AI model contributed to deriving a full key-recovery attack against the HAWK-256 post-quantum signature scheme and accelerated a seven-round AES-128 attack by 200 to 800 times. The HAWK attack leverages an previously unexploited symmetry in the underlying lattice, with a reference implementation completing in approximately three hours and 42 minutes on a 96-core server.
Why it matters: Cryptography practitioners should monitor HAWK-256 adoption and AES-7 security assumptions; faster attacks on reduced-round AES suggest accelerated timelines for evaluating cryptographic resilience, though neither HAWK-256 nor seven-round AES are standard deployments.

Claude AI Just Cracked a Post-Quantum Test Scheme and Found a Faster 7-Round AES Attack
Anthropic reported that its Claude Mythos Preview model assisted researchers in deriving a complete key‑recovery attack against the HAWK‑256 post‑quantum signature scheme. The same model also revealed a method that speeds up attacks on seven‑round AES‑128 by a factor of 200 to 800 compared with prior approaches. Anthropic released a proof‑of‑concept implementation that estimates the HAWK attack would run in roughly three hours and forty‑two minutes on a 96‑core server.
Why it matters: Organizations using HAWK‑256 or seven‑round AES‑128 should evaluate their exposure to these new key‑recovery techniques and consider migrating to stronger, vetted alternatives.
