Overview
- Multiple outlets reported Monday that the NSA has secured access to Anthropic’s restricted Mythos Preview even though the Defense Department labeled the company a supply‑chain risk and moved to cut off its tools.
- Mythos is designed to hunt and chain software bugs at scale, and Anthropic says the preview has already surfaced thousands of serious flaws across major operating systems and web browsers.
- Access is tightly gated under Project Glasswing, which lets about 40 vetted partners such as Amazon, Microsoft, Apple, Nvidia, Google and JPMorgan Chase use the model to scan their own systems for exploitable weaknesses.
- The NSA’s use surfaced days after Anthropic CEO Dario Amodei met Friday with White House officials, who called the talks productive as agencies outside the Pentagon explore controlled engagement.
- Anthropic is challenging the Pentagon action in court with mixed early rulings, while U.K. authorities and financial regulators have begun risk briefings that warn Mythos could shorten the time from bug discovery to real‑world attacks on banks and critical infrastructure.
