Anthropic: Claude Discovers Weaknesses in Encryption Algorithms, Poses Theoretical Threat to Post-Quantum Security
Anthropic stated that Claude Mythos Preview discovered improved attack methods against the post-quantum signature candidate scheme HAWK during cryptographic research, and reduced the effective key strength of HAWK-256 from 264264 to 238238, lowering the theoretical cracking cost.
Navigating Web3 tides with focused insightsTechFlow reports, on July 29, Anthropic stated that Claude Mythos Preview discovered improved attack methods against the post-quantum signature candidate scheme HAWK in cryptographic research, reducing the effective key strength of HAWK-256 from 264264 to 238238, lowering the theoretical cracking cost. Meanwhile, Claude also proposed an improved attack against 7-round Advanced Encryption Standard (AES), with speed improved by 200 to 800 times compared to existing methods.
Currently, HAWK has not yet entered actual deployment, and the related research will not affect the security of existing production systems. Anthropic stated that this achievement was obtained after the model independently completed literature review, mathematical reasoning, and experimental verification under limited guidance from cryptographers.
