This comprehensive guide will provide tips on how to protect both Android TV and Samsung Smart TV models from viruses and other malware.
Understanding the Risks
Before learning how to protect your smart TV, it’s important to understand the risks you face. Smart TVs contain many of the same components as smartphones and computers. This allows them to connect to the internet, download apps, and store data. However, it also provides potential entry points for cybercriminals. Some of the key risks include:
- Malware infections – Like any device, smart TVs can be infected with malware. Viruses, spyware, ransomware and other threats may attempt to infect your TV via malicious apps, infected files, phishing websites, or network-based attacks. Once installed, malware can steal data, brick your device, display intrusive ads, or spy on you.
- Insecure default settings – Many smart TVs ship with insecure default settings such as weak passwords, outdated software, and enabled debugging options. These settings allow attackers to easily gain access and take control.
- Vulnerable apps – Smart TV app stores are not as tightly controlled as smartphone app stores. Malicious apps containing viruses can slip through vetting processes. Outdated apps with known vulnerabilities are also risky.
- Invasive data collection – Some smart TV manufacturers and app developers engage in excessive data harvesting from viewers. Your viewing habits, location, and other personal data may be collected and sold without your consent.
- Lack of updates – Unlike smartphones which are regularly updated, many smart TV models receive infrequent or no security patches at all. This allows vulnerabilities to persist, which can be exploited by malware.
- No endpoint protection – Antivirus software is commonplace on computers and smartphones, but not smart TVs. Very limited endpoint security options exist, making malware removal difficult.
Being aware of these threats will help you understand the importance of properly securing your smart TV.
Securing Your Android TV
Android TV is a version of the Android operating system customized by Google for the larger screens and input methods of smart TVs. It powers many smart TVs manufactured by Sony, Hisense, Xiaomi, Nokia and more. If you own an Android TV, here are steps you should take to protect it:
Use Strong Passwords
Like any device, using strong passwords is one of the most basic security measures for your Android TV. Every Android TV has options to set passwords for unlocking the device, accessing settings, and purchasing apps or content. Avoid weak passwords like “1234” or “password” that are easy to crack. Instead, use randomized passwords with upper and lower case letters, numbers, and symbols. Password managers like LastPass can help you generate and store unique passwords. Also be sure to change default passwords set by the manufacturer.
Update Software Regularly
Software on your Android TV should be kept fully up to date to ensure you have the latest security patches. Bug fixes and patches are frequently released that address vulnerabilities that could be exploited by malware. To update, go to Settings > Device Preferences > About > System Update. Check for updates often and install them as soon as they become available. Enable automatic updates if possible so you don’t have to constantly remember to check.
Only Install Trusted Apps
One of the main infection vectors for malware on Android TVs is malicious apps. Stick to downloading apps from the official Google Play Store found on your Android TV. Avoid sideloading apps from third party stores or unknown sources. The Google Play store vetts apps better and provides protection against malware tainted apps. Also check app reviews and only install apps from reputable developers. Make sure to review the list of permissions an app requests during installation. Overreaching permissions could indicate malware.
Run antivirus Scans
Antivirus software designed for Android TV is available that can periodically scan for malware or viruses. Options like Bitdefender TV Antivirus or Kaspersky Safe Kids for Android TV can be installed for real time monitoring. Antivirus apps will notify you of any malicious apps found and prompt you to remove them. This can help detect and eliminate any malware that may have slipped through.
Disable Debugging and Unknown Sources
Most Android TVs have Developer Options that enable USB debugging, app sideloading, mock locations and other capabilities. These are handy for developers but also introduce security risks. Disable USB debugging in Settings to prevent attackers from compromising your TV via USB connections. Also disable Install Unknown Apps to block installation of sideloaded apps that haven’t gone through Google Play vetting. Don’t enable Developer Options unless you absolutely require them.
Connect Wi-Fi Securely
Always ensure you connect your Android TV to a secure Wi-Fi network with encryption like WPA2 or WPA3 enabled. This will prevent snooping of data sent between your TV and router. Avoid open Wi-Fi networks that lack encryption. Also position your Wi-Fi router in a central location so your Android TV can connect with a strong signal. Weak Wi-Fi signals can allow data interception more easily. Use wired Ethernet connections for the most secure option if possible.
Limit Tracking and Permissions
Like smartphones, Android TVs request access to various data such as location, microphone, camera and contacts. Be very selective in what permissions are granted. Disable any unnecessary permissions and limit sharing of personal data. Also monitor settings and apps for any tracking options and opt out of data collection where possible. Reducing data exposure will lower your risk.
Following these tips will significantly improve the security posture of your Android TV. But proper configuration is still required…
Securing Your Samsung Smart TV
Samsung is one of the most popular smart TV brands with their advanced Tizen operating system. While Samsung TVs offer great features, their connectivity also warrants security precautions. Here are some ways to protect your Samsung Smart TV from malware and hackers:
Use the App Store Safely
The Tizen Store available on Samsung TVs offers apps, games and streaming services to enhance your TV. However, malicious apps can still be present. Stick to installing well-known apps from reputable developers. Check ratings, reviews and download numbers to gauge an app’s legitimacy before installing. Be wary of apps that demand unnecessary permissions or seem sketchy.
Install Antivirus Software
Specialized antivirus solutions like Bitdefender Home Scanner and Norton 360 Deluxe can be installed on Samsung TVs to detect viruses or malware. These will monitor for malicious apps and files and notify you of any threats found. This will provide layered protection in case a bad app makes it onto your TV.
Enable Automatic Updates
New vulnerabilities in Tizen are constantly uncovered, so having the latest software is critical. Navigate to Settings > Support > Software Update on your Samsung TV to enable automatic updates. This ensures you always have the most secure firmware without having to remember to manually update. Install updates as soon as they become available.
Use Strong Samsung Passwords
Set strong alphanumeric passwords for your Samsung account, Smart Hub login and screen lock PIN. Avoid obvious passwords that could be easily guessed. Regularly change these credentials as well to maintain security, especially if you suspect any passwords may have been compromised. Enable password visibility off to prevent onlookers from snooping them.
Connect Wi-Fi Securely
Never connect your Samsung Smart TV to unsecured public Wi-Fi networks. Make sure your home Wi-Fi has modern WPA2 or WPA3 encryption enabled to prevent data interception. For content streaming that requires more bandwidth, use wired Ethernet connections which are more secure. Place your Wi-Fi router centrally in your home so your TV can connect with a strong signal.
Disable Remote Access Features
Options like Remote Access allow you to access your Samsung TV from other devices like smartphones. While convenient, these provide another avenue for hackers to access your TV. Disable Remote Access under System > Expert Settings if it is not actively used. Also disable Anynet+ (HDMI-CEC) to prevent TV control via HDMI connections if not needed.
Limit Use of Cloud Services
Features like Cloud Gaming rely on online cloud connections. While useful, frequent cloud connections can increase exposure. Disable Cloud Gaming under General Settings if not regularly used. Also limit SyncPlus and other cloud syncing features to only essential accounts. The less you connect to the cloud, the lower your risk profile.
Opt Out of Data Collection
Review Samsung’s privacy policy and opt out of any non-essential data collection where possible. Disable permissions for tracking and limit services that share usage data. Samsung Health also accumulates personal fitness data that could be valuable for hackers. Disable Health sync options and turn off if not being used. The less data exposed, the better.
