On April 7th, Anthropic announced Claude Mythos Preview, a new AI model that it said possessed particularly strong cybersecurity capabilities. Some of these capabilities, according to Anthropic’s blog post, were not the result of deliberate training, but rather emerged as a consequence of general improvements.

Mythos independently identified and patched a 16-year-old vulnerability in the online media library FFmpeg. It also escaped a restricted sandbox and leaked information to the open internet. Anthropic says “it’s about to become very difficult for the security community” and is not releasing Mythos Preview for general-public users. Instead, it is setting up Project Glasswing to share a limited version of the model with AWS, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, NVIDIA, and Palo Alto Networks, for “defensive security work”.
