Project Glasswing Grows as Anthropic Extends Claude Mythos Preview Program

Anthropic expanded Project Glasswing to roughly 200 partner organizations worldwide, using the Claude Mythos Preview model to identify over 10,000 high- and critical-severity vulnerabilities across codebases in critical sectors (energy, healthcare, telecoms, water, hardware). The program supports automated patch generation, pre-release audits, AI-driven penetration testing, and plans for a Cyber Verification Program, while warning that similar AI capabilities could be misused by threat actors and emphasizing collaboration to improve disclosure and remediation workflows.
