Summary

Anthropic released Claude Mythos Preview, an advanced AI model that excels at finding security vulnerabilities (weaknesses in software), but is limiting access to a select group of companies through a program called Project Glasswing to prevent attackers from misusing it. The model can identify bugs that were previously hard to detect, including a 27-year-old bug in OpenBSD (an operating system focused on security), and Anthropic is working with U.S. government agencies to manage the risks of this powerful cybersecurity capability.

Solution / Mitigation

Anthropic is limiting access to Claude Mythos Preview by only providing it to a select group of companies, including Apple, Google, Microsoft, Nvidia, and Amazon Web Services, along with over 40 other firms, for defensive security work. Additionally, the company stated it 'has been in ongoing discussions' with U.S. government officials including the Cybersecurity and Infrastructure Security Agency and the Center for AI Standards and Innovation about the model's cyber capabilities.
