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.
