Anthropic's Mythos AI poses global cybersecurity risk

Anthropic has developed an AI model, Mythos Preview, capable of identifying thousands of major cybersecurity vulnerabilities, including in all major operating systems and browsers. This power, typically reserved for elite hacking groups, is now held by a private company. Anthropic is limiting access to Mythos Preview through Project Glasswing, aiming to use it for defensive purposes and share findings. Experts warn that AI's hacking capabilities are advancing rapidly, posing a significant threat to global infrastructure.

Anthropic's new AI too dangerous for public release

Anthropic is limiting the release of its powerful AI model, Claude Mythos Preview, to select technology firms and organizations building critical software infrastructure. This initiative, called Project Glasswing, aims to use the AI's vulnerability detection capabilities for defensive cybersecurity purposes. Anthropic warns that such powerful AI could be used by hackers and foreign adversaries to exploit weaknesses, potentially causing severe economic and national security fallout. The company is committing significant resources to support this defensive effort.

GitHub Copilot faced outages in March 2026
