Smart TVs are becoming increasingly common as they are a great way to enjoy your favorite shows and movies, but many people don't realize they are vulnerable to cyberattacks.

Since smart TVs are connected to the internet, they can become targets of cybercriminals who use malicious software to breach the privacy and security of your device. Fortunately, there are some steps you can take to keep your smart TV secure.

So, how can attackers hack your smart TV, and how can you protect your smart TV from cyberattacks?

Can a Smart TV Be Hacked?

Yes, smart TVs can be hacked by a highly qualified and advanced individual hacker or a group of hackers. Cybercriminals are increasingly targeting smart TVs to access personal information such as bank details, passwords, and other sensitive information. In fact, every IoT device you use, such as security cameras, refrigerators, and even toasters, is vulnerable to cyberattacks and could be hacked.

While watching your favorite movie or TV show on your latest smart TV, you might not realize that cybercriminals are targeting you. Cybercriminals can use malware and other malicious software to take control of your device, gain access to your personal information, and even spy on you through your TV's webcam.

Signs Your Smart TV Is Hacked or Infected

If you suspect that your smart TV has been hacked or infected with malware, there are several signs you should look out for. Some of these signs include:

  • Unexpected pop-up ads or messages: If you see pop-ups or messages on your screen that you didn't expect, it could be a sign of malware.
  • Unresponsive remote control: If the buttons on your remote are suddenly failing to work as expected, and if there are no other issues like battery drain, then this could indicate malware has infiltrated the device.
  • Slow performance: If your smart TV is suddenly taking longer to respond than usual, it could indicate that malware is slowing the system down.
  • Unusual network activity: If you notice unusual or suspicious network activities on your smart TV, this could be a sign of malicious software.
  • Unrecognizable applications: If you start seeing applications on your smart TV that you don't recognize installing, it indicates that a malware program has infected the device.
  • Changes in settings without your knowledge: If the settings of your smart TV, such as the background color or language, have changed without you doing anything, it indicates that something is wrong with your device.

Fortunately, there are some steps you can take to protect your smart TV from cyberattacks.

1. Keep Software or Firmware Updated

Many users ignore the software and firmware updates when it comes to the smart TV. However, it is extremely important to keep the software of your smart TV updated as this can help protect against security vulnerabilities and other bugs. Updating your smart TV is as essential as updating your smartphones and computers.

2. Secure Your Wi-Fi Router

Make sure yousecure your Wi-Fi router. This will keep not only your smart TV safe but also the other connected devices. Installing a virtual private network (VPN) on your router is an excellent way to secure your router and protect your smart TV from cyberattacks. A VPN will make it harder for malicious actors to access or intercept your data by ensuring that any data sent to or from your smart TV is encrypted and protected against cyberattacks.

Other than that, use strong passwords and multi-factor authentication to secure your router further.

3. Use a Secure Network

When setting up your smart TV, make sure you use a secure network from a reputed ISP. Also, ensure the network is encrypted with WPA2 or some other strong encryption to protect your data from being accessed by any malicious actors.

4. Activate the TV's Firewall

Most modern smart TVs come with a built-in firewall. A firewall will help prevent unauthorized access to your device and make it harder for hackers to gain access to your personal information. Check and enable your smart TV's built-in firewall option, as this can help protect the device against malicious software and cyberattacks.

5. Disable Automatic Connections

When setting up your smart TV, turn off any automatic connections to networks or applications. This will prevent any malicious actors from accessing your device without your knowledge.

6. Set a PIN or Password for Your Smart TV

Most TVs come with a PIN code or password you can set up when you first set up the device. Remember to change this pin code or password periodically, and never share it with anyone. This will help protect your smart TV from unwanted access.

7. Be Careful With Unknown Sources

When it comes to downloading apps or streaming content on your smart TV, always be careful when dealing with unknown sources. You should only download applications from trusted sources and avoid clicking any suspicious links or downloading any files from websites that look shady or untrustworthy.

8. Avoid Connecting Unsecured Devices

Whenever possible, avoid connecting unsecured devices to your smart TVs, such as virus-infected USB drives or other devices. Unsecured devices can be a gateway for malicious software to gain access to your TV.

9. Be Wary of Unsolicited Pop-Ups

If you receive any unsolicited pop-ups on your smart TV, be suspicious. These could be attempts to install malicious software or access your personal information. Always verify the source of any unsolicited messages before taking any action.

10. Limit Access to Your Smart TV

Smart TVs come with the option to wirelessly connect other devices with them. You should put a limit on who can access your device. Set up user accounts and passwords so that only authorized users are able to access the TV. When you do connect a device, check if it is a secure one with up-to-date security measures in place.

11. Disable Unused Features

Most modern smart TVs come with a variety of features that you may not need. Make sure to disable any unused features, as this will reduce the chances of your TV being hacked by malicious actors.

12. Monitor Your Smart TV Activity

Make sure to monitor your smart TV for any suspicious activity. This includes keeping an eye on any network activity, changes in settings, or other unusual behavior. If you see anything that is out of the ordinary, take immediate action to protect your device.

13. Cover the Webcam of Your Smart TV

One of the most important things to do is to cover the webcam when you are not using it. This will prevent anyone from being able to view your activities or use the camera for malicious purposes.

14. Don't Allow Data Gathering

Many smart TVs have the ability to collect data about you and your viewing habits. You should limit this data gathering by turning off any features that allow for it. This will help protect your personal information from being used without your consent.

15. Restrict Always-On Access by Microphones or Cameras

If your smart TV has a microphone or camera, make sure to restrict always-on access. This will prevent any malicious actors from listening in on your conversations or using the camera for nefarious purposes.

Stop Your Smart TV From Spying on You

Protecting your smart TV from cyberattacks is essential for the security of your personal information and data. While no technology is impenetrable, taking preventive steps will go a long way in ensuring that your smart TV and other smart devices are secure.
