Claude Mythos Cracks Post-Quantum Signature Scheme, Raising New Questions for Cryptography - Tekedia

Claude Mythos reportedly found a vulnerability in a post-quantum digital signature scheme during advanced security testing.

The discovery came from analyzing implementation details and protocol behavior, not from brute-force attack methods.

The case suggests AI could become an important tool for uncovering cryptographic flaws before quantum-resistant systems are widely deployed.

That could strengthen long-term security for banking, software updates, blockchain, and secure messaging.
