Summary
Anthropic's Claude Mythos, an AI model designed to find bugs in software, has been distributed to select government agencies and industry groups through a program called Project Glasswing, but the US cybersecurity agency CISA does not have access yet. Unauthorized users from a private Discord community have also gained access to Mythos and have been using it regularly, raising concerns since the model could potentially be used to discover and exploit software vulnerabilities.
