“Beyond the risk that your TV manufacturer and app developers may be listening and watching you, that television can also be a gateway for hackers to come into your home. A bad cyber actor may not be able to access your locked-down computer directly, but it is possible that your unsecured TV can give him or her an easy way in the backdoor through your router,” wrote the FBI.
The FBI warned that hackers can take control of your unsecured smart TV and in worst cases, take control of the camera and microphone to watch and listen in.
Active attacks and exploits against smart TVs are rare, but not unheard of. Because every smart TV comes with their manufacturer’s own software and are at the mercy of their often unreliable and irregular security patching schedule, some devices are more vulnerable than others. Earlier this year, hackers showed it was possible to hijack Google’s Chromecast streaming stick and broadcast random videos to thousands of victims.
