"If you enable Voice Recognition, you can interact with your Smart TV using your voice. To provide you the Voice Recognition feature,
some interactive voice commands may be transmitted (along with information about your device, including device identifiers) to a third-party service provider
(currently, Nuance Communications, Inc.) that converts your interactive voice commands to text and to the extent necessary to provide the Voice Recognition features to you.
In addition, Samsung may collect and your device may capture voice commands and associated texts so that we can provide you with Voice Recognition features and evaluate and improve the features."

"Today, Tuesday 7 March 2017, WikiLeaks begins its new series of leaks on the U.S. Central Intelligence Agency. Code-named "Vault 7" by WikiLeaks, it is the largest ever publication of confidential documents on the agency."
"'Year Zero' introduces the scope and direction of the CIA's global covert hacking program, its malware arsenal, and dozens of 'zero day' weaponized exploits against a wide range of U.S. and European company products, include Apple's iPhone, Google's Android and Microsoft's Windows, and even Samsung TVs, which are turned into covert microphones.
"Since 2001 the CIA has gained political and budgetary preeminence over the U.S. National Security Agency (NSA). The CIA found itself building not just its now infamous drone fleet, but a very different type of covert, globe-spanning force — its own substantial fleet of hackers.
"The agency's hacking division freed it from having to disclose its often controversial operations to the NSA (its primary bureaucratic rival) in order to draw on the NSA's hacking capacities."

"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 surely its most emblematic realization.
"The attack against Samsung smart TVs was developed in cooperation with the United Kingdom's MI5/BTSS.
"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."
