Summary
Claude AI (an LLM, or large language model) discovered a faster way to attack HAWK-256, a post-quantum cryptography scheme (encryption designed to resist future quantum computers), and found a significant speedup for attacking a simplified version of AES-128 (a widely-used encryption standard). However, Anthropic, the company behind Claude, stated that neither attack affects real production systems in use today, and HAWK's larger security parameters remain impractical to break.
