Millions of cheap Android TV boxes come pre-infected with botnet malware

If you’re still using an older Android TV device that you bought from Amazon, it might be time to upgrade to one of the best streaming devices. Back in May, we reported about a wave of malware that was being used to infect budget Android TV boxes — now it appears that a second botnet has been discovered on some of the same devices. 

The Android TV devices in question are made by AllWinner and RockChip, two Chinese-based companies that have hundreds of '5-star reviews' on Amazon. Those devices can be used for launching “powerful DDoS attacks” or will secretly download a clickbot that will click on ads in the background to commit ad fraud for the device’s manufacturer. 

According to Russian IT-security solutions vendor Dr. WEB, the malware on the device can be acquired in one of two ways — it’s either put there via a firmware update from the manufacturers or can be a side-effect of downloading third-party streaming apps that promise free content. 

It’s important to distinguish between devices made by Sony or Google — like the Chromecast with Google TV — and devices like these budget Android TV boxes. The former use an official version of Google TV or Android TV while the latter use the Android Open Source Project platform that’s available for anyone to download and modify.

The less-known dangers of pirating content

One of the ways the trojan virus moves from machine to machine is via illegal streaming software that's commonly used to pirate movies and TV shows. These apps promise to give you easy access to the newest movies as soon as they're available digitally, but are often dodgy both legally and  from a security perspective.

If you’re using a third-party device to pirate content you will very likely want to toss it out for something that’s more secure — or, you know, not pirate content. 

That being said, however, if you use an Android TV or Google TV device from a reputable maker and strictly use it for on-the-level streaming from apps like Netflix and YouTube, there’s nothing to worry about. Those apps might use or sell your data, but they aren't using your devices for extra computing power to execute widespread acts of cyberterrorism.
