Smart TVs have fundamentally transformed how we approach and consume media. They make it effortless to binge-watch your favorite shows or stream all the obscure movies you could ever want on a whim.
However, smart screens don’t mean smart security. Most TVs are based on Android or other mobile operating systems and come with risks similar to those of your phone.
Here are the threats you should be aware of and how to stay safe.
What Cybersecurity Risks Do Smart TVs Pose?
Security-wise, smart TVs are problematic on multiple levels. It’s not uncommon for such TVs to fall victim to cyberattacks. However, their regular operation can be ethically suspect even when they’re otherwise secure.
It’s no secret that TV manufacturers collect data on your usage. This is usually done transparently, if you can categorize a clause buried within the mile-long terms of service as such. However, there have been incidents where TV manufacturers were found guilty of and fined for collecting information on user viewing habits and selling it to advertisers without consent.
Then there’s the matter of hardware security. Modern smart TVs have microphones for home assistant integration and voice-based browsing. Some more advanced models also come with built-in webcams that are convenient for motion controls and video conferencing.
A few years ago, the CIA and MI5 developed a program called Weeping Angel that could allegedly take control of smart TV microphones and cameras, effectively surveilling the population. In comparison, a since-amended Samsung privacy policy that gave the company the right to record and transmit audio to third parties is only a bit less dystopian.
Hacking threats
Smart TVs are also ripe for various cyberattacks. Manufacturers help their planned obsolescence by discontinuing OS and firmware updates after a few years, leaving hackers free to find backdoors or take advantage of other unpatched vulnerabilities.
This can have various consequences. Some cybercriminals want to gain access to the TV so they can monitor users’ habits or collect any credentials they enter when using the TV’s outdated built-in internet browsers. Others infect smart TVs with malware that adds them to botnets, directing them to connect to websites as part of Distributed Denial of Service (DDoS) attacks.
Then there’s ransomware. FLocker made headlines almost a decade ago by locking up smart TVs with a fake law enforcement message and demanding victims pay a ransom via iTunes gift cards. More recently, an app promising smart TV remote functionality was found to contain malware as well.
How to Keep Yourself and Your TV Safe?
Since the attack vectors are numerous and varied, comprehensive smart TV protection requires a multi-faceted approach.
Start by checking that the OS and all installed apps are up to date and turn automatic updates on. That way, you’re getting both new features and fixes for all the bugs or exploits the developers are aware of. Seriously consider purchasing a new TV once its OS stops receiving updates.
Alternatively, keep the TV but disconnect it from the internet and get a newer TV box instead. You’ll only pay a fraction of the price, especially if it’s a high-end TV, while reaping the benefits of newer software and possibly even quicker response times.
Next, install a VPN on the TV and make sure it stays active whenever it is on. Whether you’re setting up a Google TV Streamer VPN or configuring VPN protection on other streaming devices, the VPN encrypts your internet connection, resulting in several security and privacy improvements.
On the one hand, an encrypted connection means all the data the TV transmits when streaming, browsing the internet, etc., remains safe from prying eyes. The VPN will also hide your IP address, making it impossible for cybercriminals or advertisers to profile or track you based on your activity. Finally, VPNs have records of known malicious websites and will block access if you get redirected or accidentally reach one.
As for surveillance, you can do one of two things. Some TVs may let you disable the camera and microphone from their settings menu. Since that might not be 100% effective, installing a webcam privacy shutter or just taping the camera over with some dark duct tape will do the trick.
By taking these steps, you can ensure that your smart TV makes your entertainment experience better without risking your privacy or security.
Conclusion
Smart TVs are far too convenient and versatile to give up on entirely. Nor should you need to, as long as you’re aware of the dangers that using them carelessly brings. Follow the safety tips we just shared and keep threats at bay.
