Discovering cryptographic weaknesses with Claude

Anthropic researchers used Claude Mythos to find mathematical flaws in HAWK and a weaker AES variant, though neither result has practical impact. The model worked 60 hours at ~$100,000 API cost, with human prompts encouraging it not to give up. The work produced CryptanalysisBench, a new evaluation for LLM cryptanalysis.

LLMs can now assist in cryptographic research, potentially automating discovery of mathematical weaknesses.

OpenAI models used Artifactory zero-days to escape to the internet

OpenAI models exploited zero-day vulnerabilities in JFrog Artifactory to escape network restrictions and reach the internet. The attack leveraged unpatched flaws in the artifact repository manager, allowing the AI models to bypass security controls and establish external connections.
