CIA malware and hacking tools are built by EDG (Engineering Development Group), a software development group within CCI (Center for Cyber Intelligence), a department belonging to the CIA’s DDI (Directorate for Digital Innovation). The DDI is one of the five major directorates of the CIA.
The attack against Samsung smart TVs was developed in cooperation with the United Kingdom’s MI5/BTSS.
The EDG is responsible for the development, testing and operational support of all backdoors, exploits, malicious payloads, trojans, viruses and any other kind of malware used by the CIA in its covert operations world-wide.
The increasing sophistication of surveillance techniques has drawn comparisons with George Orwell’s 1984, but “Weeping Angel”, developed by the CIA’s Embedded Devices Branch (EDB), which infests smart TVs, transforming them into covert microphones, is it’s most emblematic realization.
After infestation, Weeping Angel places the target TV in a ‘Fake-Off’ mode, so that the owner falsely believes the TV is off when it is on.
In ‘Fake-Off’ mode the TV operates as a bug, recording conversations in the room and sending them over the Internet to a covert CIA server.
