Anthropic announced Monday that its Claude Mythos Preview model discovered mathematical weaknesses in two cryptographic algorithms, halving the effective key strength of the post-quantum signature sch…
Anthropic's Claude Mythos Preview found weaknesses in key cryptographic algorithms, including a better attack on the post-quantum signature scheme HAWK that human experts had reviewed for more than tw…
Anthropic said on July 28 that its controlled-access Claude Mythos Preview model helped researchers improve the best-known attack on HAWK, a post-quantum signature candidate that advanced to the third…
Anthropic's Claude Mythos Preview model found improved attacks against the HAWK post-quantum signature scheme and a reduced-round AES, but verifying the results took researchers nearly a month, highli…
Anthropic's Claude found weaknesses in reduced-round ciphers and the NIST post-quantum candidate HAWK, but full-strength AES-128 remains secure. Each attack cost about $100,000 in API spend and target…
Anthropic announced that its Claude Mythos Preview model discovered improved attacks against two cryptographic algorithms, significantly weakening the post-quantum digital signature scheme HAWK and im…
Anthropic's unreleased Claude Mythos Preview model has discovered two cryptanalytic weaknesses: an attack that halves the effective key strength of the post-quantum digital signature scheme HAWK, and …
Anthropic's Claude Mythos AI model autonomously identified vulnerabilities in HAWK, a candidate post-quantum digital signature scheme, in 60 hours—a task that took human cryptographers two years. The …
Researchers at Anthropic used Claude Mythos Preview to discover cryptographic weaknesses, including an improved attack on the HAWK digital signature scheme that cuts its key strength in half and a new…
Cloudflare warns that post-quantum signature algorithms under development will not be ready in time for the migration to quantum-safe cryptography, forcing reliance on the already-standardized ML-DSA …
