Having a “smart-home” is one of the many benefits to come from modern technology. This, of course, is when your everyday appliances connect to the internet and give you more information and control than imaginable. You can even control these amazing Internet of things (IoT) items with your virtual assistant of choice.
Some of the more popular IoT gadgets are smart TVs. They have undoubtedly changed the way many of us watch television. However, if you own a smart TV, there is a new security risk that you need to know about.
Why your smart TV could be putting your security at risk
Researchers are warning smart TV owners about a new proof of concept hack that could jeopardize your security. Rafael Scheel demonstrated how the hack works at a recent European cyber security seminar. The scariest thing about the hack is the scammer wouldn’t even need physical access to your television.
To gain access to your TV, all the criminal needs is a low-cost transmitter. The scammer would send a terrestrial radio signal that could be picked up by any smart TV in the area. This malicious signal would give the cybercriminal complete control over any television that picked it up.
Scheel tested the hack on Samsung smart TVs that have known security vulnerabilities in the web browsers that run in the background. The malicious signal allowed the hacker to gain privileged root access to the televisions. Although this was only tested on Samsung models, other brands that have similar flaws would most likely be vulnerable to this hacking technique as well.
Once the hacker has access to the TV they can cause harm in many ways. The hacker could spy on the victim through the television’s camera and microphone. They could also attack other gadgets connected to the home Wi-Fi network, putting personal data and credentials at risk.
How to protect your privacy
Luckily, this hack is only a proof of concept at this point and isn’t currently being used in the U.S. However, this does point out that Internet-of-Things (IoT) gadgets come with a certain amount of risk.
