If your Amazon Fire TV suddenly stops playing video and acts sluggishly, you might actually be experiencing the effects of something called ADB.Miner. Transforming television sets into mining equipment for the hacker’s wallet, the virus first makes its presence known by revealing itself as a test application called “com.google.time.timer.”
The original discovery of this attack came from a user at the XDA Developers forum complaining about an app called “test,” which doesn’t have a presence in the app store, popping up and forcing the video to stop. At worst, the television suddenly crashes because it fails to process any input because its resources are then dedicated to mining cryptocurrency.
This isn’t the first time we hear of ADB.Miner. A few months ago, it managed to spread to 5,000 Android smartphones in only 24 hours.
However, since Amazon Fire TV runs on Android, it was only a matter of time before the virus hit this type of device as well. Netlab’s discovery of the mining malware revealed that it scans devices for port 5555, typically used by Android’s system for debugging purposes.
