“Multiple devices reporting to this factory Android TV Box backdoor were ‘phones.’”
The backdoor ships from the factory. Bitsight tracked roughly 38,000 of these boxes phoning home to a Fengwo Group domain and pulling in about $50,000 a day in ad fraud by pretending to be mobile handsets. Amazon, Best Buy and Newegg are still listing them. At $30 a unit the hardware is not the product. You are paying to host a criminal proxy in your living room.
