A class action filed in federal court in Newark claims Samsung Electronics America Inc. fails to adequately notify users that the company’s Smart TVs listen to their private conversations and shares them with third parties.

A lack of security precautions in Samsung Smart TVs permits their use by the CIA as covert listening devices, sending conversations over the internet to a covert agency server, the suit claims. The suit cites a release of documents about the agency’s techniques by WikiLeaks that was reported in the New York Times on March 7. The suit echoes a Feb. 24 Federal Trade Commission complaint filed by the Electronic Privacy Information Center, which seeks an investigation of Samsung Smart TVs.
