Samsung is "urgently" investigating claims from WikiLeaks that intelligence agencies have used the company's smart TVs as part of tools to spy on users.
The whistleblowing website has published thousands of documents it claims reveal the various hacking tools used by the CIA in the US, including techniques that target consumer software such as Windows, Google's Android and Apple's iOS.
The leaked report also claims software was developed to turn Samsung smart TVs into listening devices, a project codenamed Weeping Angel, which the report claims also included input from the UK's MI5.
The Korean technology giant says it is investigating the claims made by WikiLeaks.
"Protecting consumers' privacy and the security of our devices is a top priority at Samsung," the company said in a statement.
"We are aware of the report in question and are urgently looking into the matter."
The leaked documents claim a "fake-off" mode was created which tricked users into believing their TV screen was off when instead it was secretly recording audio that would be sent to CIA servers once the screen was turned back on and an internet connection re-established.
