Anthropic has revealed that its Claude Mythos Preview AI model uncovered a major weakness in HAWK, a proposed post-quantum digital signature algorithm designed to secure future online banking, web payments, and other digital transactions. The discovery highlights how advanced AI could accelerate cryptographic research and reshape the race toward quantum-resistant security. According to Anthropic, Claude spent roughly 60 hours analyzing HAWK at a computing cost of about $100,000. The AI identified an attack that reduces the effective key strength of HAWKs smallest parameter set from an… Read more
