Mythos takes its first shot at post-quantum cryptography

Anthropic's Claude Mythos Preview AI model helped researchers discover faster attacks against two cryptographic algorithms: Hawk (a candidate post-quantum signature algorithm being evaluated by NIST) and a weakened version of AES (Advanced Encryption Standard, a widely used encryption method). However, neither attack threatens real-world security because the Hawk attack only works on smaller key sizes that aren't being deployed, and the AES attack requires impractical conditions like access to billions of encrypted outputs.
