Wikileaks has published another set of hacking tools belonging to the American intelligence agency. The latest revelation includes a user guide for CIA's "Weeping Angel" tool which was derived from another tool called "Extending" which belongs to UK's intelligence agency MI5/BTSS.
Extending takes control of Samsung F Series Smart TV. The highly-detailed user guide describes it as an implant "designed to record audio from the built-in microphone and egress or store the data".
According to the user guide, the malware can be deployed on a TV via a USB stick after configuring it on a Linux system.
It is possible to transfer the recorded audio files through the USB stick or by setting up a WiFi hotspot near the TV. Also, a Live Liston Tool, running on a Windows OS, can be used to listen to audio exfiltration in real-time.
Wikileaks mentioned that the two agencies, CIA and MI5/BTSS, made collaborative efforts to create Weeping Angel during their Joint Development Workshops. Clearly the Russians found out about it and by releasing the tools through Wikileaks they can be re-assured that the CIA will not be using them on Russian Samsungs.
