Mythos attack on 3rd-round PQC algorithm candidate puts it out of commission
Ars Technica Dan Goodin
Anthropic's Mythos security model discovered a critical flaw in HAWK, a post-quantum cryptography algorithm that was a candidate for US standardization by NIST, leading its developer to withdraw it from consideration. HAWK had advanced through two rounds of NIST testing and was in the third round when the vulnerability was identified. The algorithm is no longer being evaluated as a potential standard for quantum-resistant digital signatures.
Why it matters
HAWK withstood years of testing that had yet to uncover a fatal weakness found through Mythos.
