Documents published by WikiLeaks on Thursday provide details on a tool allegedly used by the U.S. Central Intelligence Agency (CIA) to hack routers and access points.

Dubbed CherryBlossom, the tool is described by its developers as a system designed for monitoring a target’s Internet activity and delivering software exploits via wireless networking devices. WikiLeaks said the tool was developed and implemented by the CIA with the help of a US-based nonprofit research center called SRI International.
