Anthropic says Claude uncovers cryptographic weaknesses, advances AI-assisted security research

Artificial intelligence firm Anthropic on Tuesday said its Frontier Red Team has demonstrated that its latest AI models are beginning to make meaningful advances in cryptanalysis, with Claude uncovering previously unknown weaknesses in widely studied cryptographic algorithms and contributing to real-world security research.

In a research paper titled “Discovering cryptographic weaknesses with Claude,” Anthropic said the work marks an early step towards using frontier AI systems to strengthen cybersecurity by identifying flaws before they can be exploited by malicious actors.
