Anthropic revealed that their Claude Mythos Preview has identified significant mathematical vulnerabilities in two key cryptographic algorithms. The first vulnerability drastically reduces the effective key strength of HAWK, a post-quantum digital signature scheme currently being evaluated by NIST. The second flaw enhances the best-known attack against seven-round AES, a widely used symmetric encryption standard, by a factor of 200 to 800 times. These discoveries highlight overlooked weaknesses despite extensive expert review.
