If you bought an inexpensive Android TV box online, it's worth five minutes of your evening to check it.
Google says a Chinese device maker called Videostrong built a hidden backdoor into the software of TV boxes it made for many brands, then sold access to criminals. They used people's boxes, and their home internet connections, for ad fraud and to pass strangers' traffic through. Google and its partners shut down the servers controlling the boxes last week, but the backdoor is still on the devices, it puts itself back after a restart, and owners can't remove it themselves.
Researchers at TrendAI counted about 1.47 million infected boxes across 206 models. Another research firm, Synthient, traced it through a MECOOL brand box.
At home, we'd start by finding your box's brand and model and comparing it with Synthient's published model list on GitHub. If it's on there, or it's an off-brand box you can't identify, unplug it and replace it with one from a known brand that's Play Protect certified. Putting smart TVs and other gadgets on your router's guest network is a good habit too, since it makes it harder for one bad device to reach your laptop or phone.
