Anthropic's Frontier Red Team published a previously unknown attack on a NIST post-quantum signature candidate, found by a multi-agent system with a human collaborator who is not a lattice cryptography specialist. Claude also produced "Möbius Bridge," a fingerprinting technique making an existing meet-in-the-middle attack on 7-round AES-128 between 200 and 800 times faster, at roughly a billion output tokens over three days and about $100,000 per primary attack. Neither result touches production: HAWK is undeployed, the AES result is reduced-round. The Hacker News reported it could not find any independent reproduction at review time and the disclosure thread had no replies. That caveat belongs in every summary of this.
