Anthropic discovers cryptographic weaknesses using Claude
Anthropic has utilised its AI model, Claude Mythos, to uncover theoretical weaknesses in the HAWK and round-reduced AES cryptographic algorithms. The findings mark a significant advancement in AI-assisted cryptanalysis.
What happened?
Using a preview version of its AI model, Claude Mythos, Anthropic has identified new theoretical weaknesses in two cryptographic algorithms. Researchers have found improved attack methods against the post-quantum-ready digital signature scheme HAWK and identified a new attack path against AES with a reduced number of rounds.

Why it matters
The progress demonstrates that large-scale AI models can be used to discover theoretical mathematical flaws in complex encryption schemes. These findings assist researchers in strengthening future security standards, particularly within post-quantum cryptography, before the algorithms are deployed for widespread use.
Who is affected?
This development is primarily relevant to cryptographers, cybersecurity researchers, and developers of security protocols. Ordinary users and businesses do not currently need to take any action, as the identified weaknesses do not pose an immediate threat to fully implemented AES encryption.
Impact on the EU
The research concerns global encryption standards used within the EU for cybersecurity and data protection. As the results pertain to theoretical and limited attacks, operational EU compliance and current GDPR protections are not affected at this stage.
What else you should know
The study was conducted by Anthropic's Frontier Red Team to evaluate the AI model's capacity for advanced cryptanalysis. The results have been reported to the relevant HAWK research groups to facilitate future improvements to the algorithm.
