A vulnerable Android TV app might risk your personal data and privacy that may lead to financial loss and even a much great damaged.

Do Exploits and Malware or Virus infect Android TV Operating System?

Yes, infact I myself have test to write and execute an exploit to my own 4K Android TV. And as expected I got my personal data and I can remotely control the Android TV. Here is how to attack the Andriod TV;

To exploit the kernel of Android TV use “CVE-2013-7263 & CVE-2013-6282” to gain privilege to the root the Android LED TV.

Then use the “Leveraging the NDK and JNI” to create an application that deliver the payload to the target Android LED TV. This payload will bring a native code application that will root and SELinux Android 6.0 device.

Use static analysis to perform a “local” attack on a target Android application to obtain sensitive information from another Android app installed on the device.

Leveraging BakSmali to decompile, and dynamic runtime analysis of native code, we will peer “into” the process space of a running Android app to see what data it is transferring in an otherwise un-man-in-the-middle-able encrypted communication with a server.

Use Chrome WebView to gain a remote code execution to the Android TV. Once execute, you need to debug an app and heapspray into system_server in preparation for an actual exploit.

Using a logic analyzer reverse engineer pinouts of Android LED TV UART interfaces.

Now will download firmware of the LED TV DIRECTLY from the manufacturer’s website, unpack it, disassemble it, find the requisite parts (bootloader, filesystem, etc.), decompile the APKs, and go on a guided tour of the native code and Dalvik code that contain many interesting tidbits.

Now you “0wn” an Android device by leveraging JTAG interface via a LED TV VGA port or service port!

Now who told you that TV’s is not vulnerable to exploits and malware or viruses. Therefore, an on time update is really important if you want to be safe.
