Overview
- Reports on Sunday said the NSA is using Anthropic’s Mythos Preview even though the Pentagon labeled the company a supply chain risk and moved to cut off its tools.
- Anthropic has kept Mythos in a gated rollout called Project Glasswing for roughly 40 vetted partners, with sources saying the NSA is among the unnamed users scanning their own systems for exploitable bugs.
- Anthropic CEO Dario Amodei met White House chief of staff Susie Wiles and Treasury Secretary Scott Bessent on Friday to discuss government use of the model, with sources describing the talks as productive.
- Regulators in Australia and South Korea on Monday said they are reviewing risks tied to Mythos and pressed financial firms to harden systems, while Singapore’s central bank urged banks to find and fix software weaknesses faster.
- UK officials urged major companies to adopt a new cyber‑resilience pledge, and British banks have sought access to Mythos, as independent tests in the UK found the model could automate attacks on weak enterprise networks once inside.
