WikiLeaks Dump Shows CIA Could Turn Smart TVs into Listening Devices
IT’S DIFFICULT to buy a new TV that doesn’t come with a suite of (generally mediocre) “smart” software, giving your home theater some of the functions typically found in phones and tablets. But bringing these extra features into your living room means bringing a microphone, too — a fact the CIA is exploiting, according to a new trove of documents released today by WikiLeaks.
According to documents inside the cache, a CIA program named “Weeping Angel” provided the agency’s hackers with access to Samsung Smart TVs, allowing a television’s built-in voice control microphone to be remotely enabled while keeping the appearance that the TV itself was switched off, called “Fake-Off mode.” Although the display would be switched off, and LED indicator lights would be suppressed, the hardware inside the television would continue to operate, unbeknownst to the owner. The method, co-developed with British intelligence, required implanting a given TV with malware—it’s unclear if this attack could be executed remotely, but the documentation includes reference to in-person infection via a tainted USB drive. Once the malware was inside the TV, it could relay recorded audio data to a third party (presumably a server controlled by the CIA) through the included network connection.
