If not regularly updated, these systems may have vulnerabilities that hackers can exploit to install malware and gain access to the TV. Therefore, it is crucial to keep the TV's software and firmware up to date.

Unverified Apps and Downloads

Cybercriminals can create malicious apps that install malware on smart TVs when downloaded. They disguise these apps as legitimate ones to trick users into downloading them. Once installed, the malware can gain access to the camera and microphone, enabling hackers to spy on users and record their activities. Therefore, users should only download apps from trusted sources and official app stores, such as Roku, Google, or Amazon.

Insecure Wi-Fi Networks

Cybercriminals can execute Man-in-the-Middle (MITM) attacks by taking advantage of weak Wi-Fi network security. In these attacks, hackers intercept data transmitted between two parties. They rely on public or unencrypted Wi-Fi networks to eavesdrop, monitor, or alter transmitted data. If a smart TV is connected to an unsecured Wi-Fi network, hackers can transmit malware to the device and gain access to its camera and microphone.

USB Drives

USB drives can be infected with malware and used to infect smart TVs. Once an infected USB drive is inserted into the TV, it may automatically install malicious software. This can happen maliciously by a bad actor or accidentally by downloading malware onto an external storage device. Therefore, users should be cautious about what they plug into their smart TVs.

Phishing Attacks

Hackers may also target smart TVs through phishing attacks. They might send malicious attachments via email or set up fraudulent websites to trick users into entering their login credentials. Once they have these credentials, they can gain access to the TV and its camera and microphone.

To protect against malware and unauthorized access to smart TVs, users should take precautions such as using strong passwords, securing their Wi-Fi networks, regularly updating their TV's software, and only downloading apps from official sources. Additionally, disabling or covering the camera when not in use can provide an extra layer of privacy protection.

Default security settings

• Use strong passwords: If your TV is regularly or continually connected to the internet, ensure that both the device itself and any installed applications use strong, complex, and hard-to-guess passwords.
• Update your TV's software: Regularly update your TV's software to the latest version available. Software updates are crucial for cybersecurity as they patch vulnerabilities and fix security flaws.
• Secure your router: Ensure that your router is secure and protected. Use strong passwords and consider enabling a VPN to encrypt any data travelling through it.
• Download apps from official stores only: Only install programs and applications from official sources. Make sure that both the app and its provider are reliable, and never grant access to your data, camera, or microphone if it isn't necessary for the app's operation.
• Turn off your TV camera when not in use: If you cannot turn off your camera, cover the lens with tape or a sticker.
• Check the manufacturer's security updates: Verify the manufacturer's ability to update your device with security patches. Check if they have done it in the past and if they plan to continue doing so.
• Review the privacy policies: Check the privacy policies of both the TV manufacturer and the streaming services you use. Understand what data they collect, how they store it, and what they do with it.
• Disable unnecessary features: If you don't need certain features like voice control, gesture control, or auto-recommender, consider disabling them in the TV's settings.
• Power off your TV when not in use: Completely power off your smart TV and unplug it when you're not using it. This helps reduce the risk of unauthorized access.
• Use a Pi-Hole: Consider using a Pi-Hole on your network, a mini-computer that filters traffic to and from your network, preventing malicious traffic and online surveillance.

Insecure Wi-Fi networks

Cybercriminals rely on unsecured Wi-Fi networks to eavesdrop, monitor, and alter transmitted data. They can use public Wi-Fi or exploit unsecured home routers to inject malware into any connected device, including your smart TV. This means that if your smart TV is connected to an unsecured Wi-Fi network, it is at risk of being hacked.

To protect your smart TV and other IoT devices, it is crucial to secure your Wi-Fi network. Here are some measures you can take:

• Use strong passwords for your Wi-Fi network. Avoid simple or easily guessable passwords.
• Regularly update your router's software to ensure it has the latest security patches.
• Create a guest network to provide separate access for guests without compromising your primary network.
• Change your router's name to remove any identifying information.
• Invest in a router that supports robust encryption protocols like WPA3 or WPA2 to protect your web traffic.
• Enable a VPN on your router to encrypt all data transmitted through it, adding an extra layer of protection.

By implementing these measures, you can significantly enhance the security of your Wi-Fi network and make it more difficult for cybercriminals to exploit vulnerabilities and gain access to your smart TV and other connected devices.

Infected USB drives

USB drives are a common way for hackers to gain access to smart TVs. Infected USB drives can be used to deliver malware, which, once loaded, can create a backdoor that gives attackers remote control of the system.

In the first half of 2023, Mandiant Managed Defense observed a threefold increase in attacks using infected USB drives to steal sensitive information. The SOGU and SNOWYDRIVE malware infections are the most prevalent USB-based cyber espionage attacks. These attacks use USB flash drives to load malware onto a host system, which then spreads to other USB flash drives and throughout the network.

• Purchase or obtain a USB flash drive: This will be the delivery mechanism for the malware.
• Infect the USB drive with malware: This can be done by tricking the user into executing a malicious file that is disguised as a legitimate executable. When the user runs the file, it will trigger a chain of malicious executions, each designed to perform a specific task.
• Insert the infected USB drive into the smart TV: Once the USB drive is inserted, the malware will automatically install and load a malicious payload.
• Gain remote access: Once the malware is installed, it will create a backdoor, giving you remote access to the system. You can then use this access to spy on the user, steal data, or infect other devices on the network.
• Maintain persistence: The malware can be programmed to maintain its persistence on the system by creating a hidden directory and copying its main components there. It can also infect new removable drives plugged into the infected system, allowing it to spread to other devices.
• Exfiltrate data: Finally, the malware will collect and exfiltrate any sensitive data it finds on the system, such as documents, spreadsheets, or PDFs.

It is important to note that hacking smart TVs and infecting USB drives with malware is illegal and unethical. This information is provided for educational purposes only and should not be used for malicious activities.
