Anthropic Deploys Free AI Vulnerability Scanner as Crypto Projects Race for Access

Anthropic launched its opt-in OSS Scanner on October 8, 2026, offering open-source projects free vulnerability detection powered by Claude Mythos, the company's highest-tier AI model—and crypto firms including Ethereum client Nethermind and Lightning wallet ZEUS are already applying. The OSS Scanner research announcement outlines an automated system that scans open-source codebases, generates security reports complete with proof-of-concept exploits and suggested fixes, and delivers findings without human pre-review to maximize speed. The initiative is part of Anthropic's broader Cyber Mission, which includes funding for critical-infrastructure projects like the Python Software Foundation and Apache Software Foundation.
