Claude finds flaws in 2 cryptographic algorithms that yrs of expert review missed

Anthropic on Tuesday said its Claude Mythos Preview model found mathematical flaws in two cryptographic algorithms that experts had missed for years. The first attack significantly weakens HAWK, a digital signature scheme that was built for a post-quantum world, the company stated. The second identifies a new way to attack round-reduced AES, the most widely used symmetric cypher, it added.
