Anthropic's Mythos Preview Model Accelerates AES Attack Speed by 200-800x in One Week
tszzl · x · 2026-07-29
Anthropic officially announced a major breakthrough by its Mythos Preview model in the field of cryptography.
- Target: A reduced version of the Advanced Encryption Standard (AES), one of the most thoroughly scrutinized encryption algorithms in existence.
- Result: Within a single week, the model discovered a method to accelerate attacks on this AES version by 200 to 800 times.
This progress highlights the immense potential of frontier AI models in solving complex mathematical and cryptographic challenges.
