Anthropic\'s new AI model \'Mythos\' is changing security priorities in the cryptocurrency industry, with attention moving beyond smart contract audits to wider infrastructure. The model is noted for linking minor weaknesses across systems into attack paths. The shift is expanding checks to key management, signing services, bridges, oracle networks and cryptography layers. The industry is also moving from pre-launch audits and post-launch monitoring to continuous audits, real-time simulation and breach-assumed design.

Crypto protocol hacking losses have surged in April, putting decentralised finance security risks back in focus. Blockchain outlet BeInCrypto reported losses topping $606.2 million in 18 days, the biggest monthly total since February 2025 and well above the $165.5 million recorded in the first quarter. KelpDAO and Drift Protocol accounted for most of the damage. DeFi total value locked fell after the KelpDAO hack, and analysts warned of broader impacts on trust and valuations.
