Claude AI Just Cracked a Post-Quantum Test Scheme and Found a Faster 7-Round AES Attack
Article summary
Quick briefing — cleaned from the original RSS feed
Anthropic says Claude Mythos Preview helped derive an end-to-end key-recovery attack against HAWK-256 and a 200- to 800-fold speedup for an attack on seven-round AES-128. The HAWK attack exploits a previously unused symmetry in the lattice behind the signature scheme. Anthropic's released implementation gives an expected end-to-end runtime of about three hours and 42 minutes on a 96-core server
