WikiLeaks publishes a manual for an alleged CIA tool that can capture remote video streams. The tool’s name is CouchPotato and is described in a usage manual dated to February 14, 2014. CIA operatives can use a command-line interface to start the tool and point it to the URL of an RTSP or H.264 video stream and the location where to save the stream on disk. It can save streams to disk in a classic AVI video format, or as JPEG images, in case the operator wants to save space.
