Claude Just Cracked Half the Strength of a Post-Quantum Cipher
Anthropic says its Claude Mythos model found real, previously-unknown weaknesses in two cryptographic algorithms. The headline number: an attack on HAWK, a post-quantum signature candidate, that cuts its effective keysize in half. This is not a “the sky is falling” story. Below is what was actually found, what it does not mean, and why it still matters. ...
