Discovering cryptographic weaknesses with Claude
Researchers have used the Claude Mythos Preview to identify vulnerabilities in cryptographic algorithms, specifically targeting the HAWK digital signature scheme and the Advanced Encryption Standard (AES). The first discovery shows an attack that effectively weakens HAWK's security by halving its key strength without affecting deployed systems, while the second improves attack efficiency on a reduced-round version of AES by up to 800 times.
