Anthropic's LLM Claude Mythos discovered cryptanalytic attacks on the post-quantum signature scheme HAWK and reduced-round AES-128, but the attacks are not practical and pose no threat to full AES. Th…
Anthropic's Claude Mythos Preview has recovered signing keys from NIST's post-quantum candidate HAWK-256 in under four hours and devised an attack accelerating seven-round AES-128 cracking by 200 to 8…
Researchers Milad Nasr and Nicholas Carlini, sponsored by Anthropic, used an AI model to improve a meet-in-the-middle attack on seven-round AES-128, reducing the complexity from 2^105 to 2^104.5 chose…
Anthropic's Claude Mythos Preview model found a new attack that lowers the estimated key-recovery cost for HAWK-512 from 2^150 to 2^108 gates and for HAWK-1024 from 2^288 to 2^182 gates, but HAWK is n…
Anthropic's Claude Mythos Preview discovered a practical key-recovery attack on the post-quantum HAWK-256 digital signature candidate in roughly 60 hours, reducing effective security from 264 to 238 o…
Anthropic published research on July 28 reporting that Claude Mythos Preview helped derive a key-recovery attack against HAWK-256 and accelerate an attack on seven-round AES-128 by 200 to 800 times. T…
