Mythos attack on 3rd-round PQC algorithm candidate puts it out of commission

Anthropic's AI system Mythos developed a new meet-in-the-middle cryptanalysis technique using a Möbius Bridge, significantly reducing inputs needed to attack a weakened AES variant. While the practical impact on standard AES is uncertain, this marks a notable advance in AI-assisted cryptanalysis. The research highlights potential challenges as AI accelerates discovery of cryptographic vulnerabilities, possibly outpacing human verification.
