ANTHROPIC has announced Project Glasswing, a cybersecurity initiative that will use a preview version of its frontier model, Claude Mythos, to identify and address security vulnerabilities. Mythos Preview has reportedly discovered thousands of high-severity zero-day flaws across major operating systems and web browsers, including a now-patched 27-year-old OpenBSD bug and a 16-year-old FFmpeg flaw, as well as a memory-corrupting vulnerability in a memory‑safe virtual machine monitor.
The model’s demonstrations include autonomously producing a web browser exploit that chained four vulnerabilities to escape renderer and sandbox protections, and solving a corporate network attack simulation that would have taken a human expert more than 10 hours. Anthropic said the initiative is an urgent defensive measure, not a generally available product, and is backed by up to $100 million in usage credits for Mythos Preview plus $4 million in direct donations to open‑source security organisations.
According to The Hacker News, the leak of related material and subsequent security lapses prompted discussions around the model’s capabilities and safeguards.
