Weeping Angel is the name of a hacking tool revealed in Vault 7, co-developed by the CIA and MI5, used to exploit smart TVs for the purpose of covert intelligence gathering. Once installed in a suitable TV, the tool enables the television to record its surroundings while appearing to be turned off (so-called "Fake-Off"). The tool was developed in 2014 as part of a joint CIA/MI5 workshop, and there's no evidence that it was ever operational.
