Things Your Smart TV Can Do
The Smart TV is loaded with an Operating System (OS). Android is the OS of choice for many brands of smart TVs, and this comes with a plethora of features:
- Additional Apps and Software Loadable
Considering that most TVs are scale-able and have options of installing apps and software from the internet app store or through the sideload option (transfer installable files using a USB drive); this device is equally vulnerable like a Laptop or a Smartphone.
- Connectability through WiFi and attachability of Bluetooth Accessories
Almost all Smart TVs come with built-in WiFi, Bluetooth as well as Ethernet connectivity. A majority of Smart TVs support various Bluetooth accessories such as Bluetooth wireless headphones, keyboards and mice and also can extended its connectivity to networks.
- File Transfers
The very feature of having inherent storage space and the ability to connect large storage devices to these Smart TVs, enables transfer of files and software with ease.

So, how do you prevent the Smart TV from being turned against by Cyber Criminals?
These are few suggestions to ensure security and also to prevent being a victim of hacks:
- Know exactly what features your TV has and how to control those features. Ask for the user manual, also study the features of all Apps and Software installed on the Smart TV.
- Don’t depend on the default security settings. Change passwords if you can – and know how to turn-off the microphones, cameras, and collection of personal information if possible. If there is no provisions to harden the device through user settings, you may think of using security utilities to plug the gap.
- If you can’t turn-off a camera, or any other susceptible interface on the Smart TV; look at options like cutting of power supply/bus connector to the interface or even look at options that are back-to-basic (for example, affixing a simple piece of black tape over the camera eye).
- Check the manufacturer’s ability to update your device with security patches. Can they do this? Have they done it in the past?, etc, etc….
- Investigate the gateway devices, for what flows through the network components by studying it logs and behaviour.
The TV, today is no more a ‘Dumb’ Device. The availability of the Smart TV is also expanding, with one to each Bed Room apart from having a few placed in the common areas. The Smart TV is also available at Corporate Offices. As it gains more features, the amount and sensitivity of the data they handle are increasingly appealing to cyber-criminals. The TVs can be misused to spy on users with the cameras and microphone or act as jumping-off points for attacks at other devices in the home and corporate offices that are placed in the networks.
Apart from Hackers/Cyber Criminal (who are aiming at financial gains), even TV manufacturers/app developers might be monitoring you and your family for business interest, corporate gains (and also to study viewing patterns) and spying. Users may have taken steps to keep cyber thieves from accessing your home computer/ mobile phones directly, but cyber security experts say it’s still possible for them to use your unsecured TV as a ‘back door’ to your router, to execute any cyber crime.
