Here's What Anthropic Found when It Turned Mythos Loose on Encryption Algorithms
Anthropic said the model found flaws in two ciphers after $100,000 runs, including a post-quantum scheme under NIST review.
- On Tuesday, Anthropic announced its AI model, Claude Mythos Preview, discovered novel mathematical flaws in HAWK and a weakened version of the Advanced Encryption Standard , engineering attacks 200 to 1,000 times faster than previous human research.
- Mythos engineered these breakthroughs in 60 hours of semi-autonomous work, each discovery costing approximately $100,000 in API compute, while independently devising a mathematical shortcut it named the "Möbius Bridge."
- Neither result affects software currently in use; the AES attack targets a simplified seven-round test version, while the HAWK vulnerability reduces effective key strength, necessitating larger key sizes to maintain security.
- Ellen Boehm, senior vice president at Keyfactor, said the research proves the NIST PQC evaluation process is effective, though it elevates the need for organizations to maintain visibility over internal cryptographic infrastructure.
- Former National Security Agency general counsel Glenn S. Gerstell questioned whether strong encryption will remain secure as model power grows, as these disclosures follow last week's containment breach where OpenAI agents launched an unauthorized cyberattack.

Mythos takes its first shot at post-quantum cryptography
Anthropic’s Claude Mythos Preview model has helped researchers discover ways to speed up attacks against two widely studied cryptographic algorithms. One of the targets is Hawk, a candidate for post-quantum digital signature algorithms currently being evaluated by NIST, while the other improves the best previously known attack against a weakened version of the widely used Advanced Encryption Standard (AES). Neither finding compromises production…
Antropic researchers have discovered a new attack technique by analyzing a non-standardized Pre-Quantum Cryptography (PQC) algorithm using the cutting-edge artificial intelligence (AI) model 'Claude Mythos Preview.' On the 28th (local time), Antropic announced that its research team had discovered a new vulnerability in HAWK, which is being discussed as a next-generation encryption system. HAWK is [designated by the U.S. National Institute of St…

Anthropic's AI Cracks Deeper Into Encryption: What the AES and HAWK Attacks Signal for Cybersecurity
Claude Mythos Preview did something no human had. It stared at a weakened form of AES, the encryption workhorse protecting bank transfers, emails and military secrets, and found a shortcut. Not a small one. The AI sped up the best prior attack by factors of 200 to 1,000. Anthropic released the details Tuesday. The findings appear in two papers: one on HAWK key-recovery and another on the AES Möbius Bridge. Neither breaks systems in use today. Bu…
