Anthropic has released a 154-page report describing how bad actors used its Claude AI system for state-sponsored surveillance, propaganda operations and more.

- Spyware in Mali -

A tech consultant in Bamako, working with junta-led Mali's state intelligence service (ANSE), used Claude Code to build "Lakana 360" -- a surveillance system capable of monitoring roughly 25 million SIM cards across the country's mobile network.

The app, which Anthropic could not disable, can capture calls, texts and voice traffic, and even identify people by their voice if they switch SIM cards.
