AI news flash: Anthropic’s Claude Mythos series models are positioned as cutting-edge AI systems specifically designed for cybersecurity, recently sparking widespread discussion in the DeFi community - if AI can scan code vulnerabilities faster than humans, can attackers also beat security teams to the punch in finding weaknesses in DeFi protocols before patches are applied? The Mythos series includes Claude Fable 5, a general-purpose model that was later suspended due to US government directives. Anthropic stated that compared to previous versions, Mythos shows significant improvements in vulnerability research, attack pattern analysis, and multi-layered security reasoning. What might take a security expert weeks to complete in code review, AI could compress into hours or even minutes, fundamentally shifting the balance between attackers and defenders.
