Anthropic is expanding Project Glasswing, its cybersecurity initiative built around the Claude Mythos Preview model, by adding 150 organizations following several weeks of work with its initial group of partners, security firms, open-source maintainers, and government agencies. Organizations joining the program must meet security requirements before gaining access, Anthropic noted.

Anthropic's Claude Mythos Preview Sparks Cybersecurity Revolution Anthropic has announced the launch of Project Glasswing, utilizing its unreleased AI model, Claude Mythos Preview, to identify and exploit thousands of critical software vulnerabilities across major operating systems and web browsers. This model has demonstrated the ability to autonomously discover zero-day vulnerabilities, including a 27-year-old flaw in OpenBSD and a 16-year-old vulnerability in FFmpeg. The initiative involves over 40 partner organizations, including tech giants like Amazon, Apple, and Microsoft, who will use the model defensively to patch vulnerabilities before malicious actors can exploit them. Anthropic has committed up to $100 million in usage credits and $4 million in donations to open-source security organizations. The decision to restrict public access to Mythos is due to concerns about its potential misuse, as it can enable even non-experts to exploit vulnerabilities. The model's capabilities represent a significant shift in cybersecurity, as it can automate vulnerability discovery faster than human experts. With 99% of the vulnerabilities found still unpatched, the urgency for defensive measures is critical. 1106 sources 70
