Anthropic's AI System Uncovers Weaknesses in Cryptographic Algorithms, Raising Security Concerns

Anthropic's AI system, Claude Mythos, has identified vulnerabilities in two cryptographic methods, including a post-quantum candidate under review by the National Institute of Standards and Technology (NIST). The AI discovered a mathematical shortcut in the HAWK digital signature scheme, which could halve its effective key strength, necessitating larger key sizes to maintain security. This finding challenges the viability of HAWK as a candidate for encryption methods resilient to quantum computing attacks. Additionally, Claude Mythos found a flaw in a simplified version of the Advanced Encryption Standard (AES), creating a shortcut that significantly speeds up theoretical attacks. Although these discoveries do not affect current software, they highlight potential future risks.

Anthropic's AI Model Discovers Weaknesses in AES Encryption, Raising Security Concerns

Anthropic's AI model, Claude Mythos, has identified new mathematical vulnerabilities in AES encryption, a critical component of internet security. The model, not yet publicly available, demonstrated an improved method to attack a simplified version of AES, which is used in online banking, encrypted communications, and data storage. The findings, published alongside two research papers, reveal that Mythos can attack a 7-round variant of AES-128, which typically runs 10 rounds, at a speed 200 to 800 times faster than previous methods. Additionally, the model halved the effective key strength of HAWK, a post-quantum signature scheme, in 60 hours. These results were shared with U.S. government and industry partners before publication.

AI Breakthrough: Mythos Model Cracks Post-Quantum Cipher in Record Time

Anthropic's AI model, Claude Mythos Preview, has achieved a significant breakthrough by identifying a structural flaw in HAWK, a leading candidate for post-quantum digital security standards, in just 60 hours. This discovery, which took two years of human cryptanalysis to attempt without success, highlights the potential of AI in cryptographic research. The AI model also developed a new attack technique, the Möbius Bridge, which significantly accelerates an existing attack on a weakened version of the AES cipher. While these findings do not currently threaten real-world data security, they underscore the capabilities of AI in identifying vulnerabilities in cryptographic systems.

AI-Assisted Security Tools Discover More Bugs, But Threat Level Remains Stable

AI-Assisted Security Tools Discover More Bugs, But Threat Level Remains Stable

AI-assisted security tools have identified over 1,000 vulnerabilities in the first half of 2026, according to a report by VulnCheck. Despite the increase in discovered vulnerabilities, the rate of exploitation remains consistent with previous years, suggesting that AI-discovered vulnerabilities are not inherently more likely to be exploited. The report highlights the role of AI systems like Anthropic's Project Glasswing and Microsoft's MDASH in enhancing vulnerability discovery. However, concerns persist about the potential for AI to fuel more attacks, although current data does not support these fears.
