US government site used Chinese AI model FBI called malicious

The Federal Register website briefly used an open-source Chinese AI search tool that the FBI has characterized as malicious. How long the tool was in use or what data it processed was not specified in the excerpt.

Why it matters: This is a concrete instance of broader US-China AI supply-chain security concerns reaching into government infrastructure itself, likely to fuel further scrutiny of open-source AI tool vetting in federal systems.
