Anthropic, co-founded by Dario Amodei and Daniela Amodei, said on July 28th that its controlled-access Claude Mythos Preview model helped researchers improve the best-known attack on HAWK, a post-quantum signature candidate that advanced to the third round of a US government standardization process in May.…
