Greg Otto writes that Anthropic's Claude Mythos Preview identified mathematical vulnerabilities in HAWK, a NIST post-quantum candidate, and a simplified version of AES. In HAWK, a shortcut was discovered within its lattice structure that halves effective key strength; for seven-round AES, the model found a "Möbius Bridge" which accelerates theoretical attacks without affecting real-world 10-round encryption used today.
* Anthropic collaborated with researchers from ETH Zurich and Tel Aviv University to develop CryptanalysisBench.
* The findings raise questions regarding how authorities should respond if large language models uncover flaws in systems protecting critical infrastructure.

Google is implementing Merkle Tree Certificates to mitigate the size increase of quantum-resistant cryptographic data for HTTPS certificates, ensuring compatibility and preventing slowdowns. This approach verifies large amounts of information with a small fraction of the data, maintaining the current 64-byte certificate length.
