Anthropic Says a Yemen-Based Cell Used Claude AI to Design Guided Missiles, Bans Its Accounts

Anthropic disclosed this week that a cell of threat actors based in Houthi-controlled northern Yemen used its Claude models to design guidance software for three parallel weapons programs — including a ballistic missile with a stated range goal above 2,000 kilometers — and that it banned the accounts involved after the group test-fired a guided rocket that appeared to fail.
