Anthropic's latest AI model identifies 'thousands of zero-day vulnerabilities' in 'every major operating system and every major web browser' — Claude Mythos Preview sparks race to fix critical bugs, some unpatched for decades

Anthropic's latest AI model, Claude Mythos Preview, has uncovered "thousands of zero-day vulnerabilities" in major operating systems and web browsers, sparking a rush to fix these critical bugs, some of which have remained unpatched for decades. The lab is collaborating with industry giants and government entities under "Project Glasswing" to proactively address these vulnerabilities before they can be exploited. Mythos' ability to identify and exploit vulnerabilities poses significant security risks, prompting responsible disclosure practices from Anthropic. While the model won't be widely available, the lab aims to prepare partners for a future where such advanced AI models become more common.
