Security experts have been sounding the alarm for years about the risks of using generic TV boxes that promise unlimited content streaming for a one-time fee, warning that they secretly rent the user’s Internet connection out to strangers. But a groundbreaking new analysis finds these devices also routinely spoof themselves as mobile phones clicking ads on AI-generated websites as part of sprawling operation that seeks to defraud online merchants and advertising networks. Pedro Falé is a threat researcher with the security firm Bitsight. Falé told KrebsOnSecurity he was able to peer inside a vast and complex ad fraud network by registering an expired domain name that was used to coordinate fake ad clicks across a particularly popular brand of these streaming devices known as H96. Falé said the domain he scooped up was previously used for telemetry, periodically collecting full hardware information and the entire list of installed apps from tens of thousands of H96 streaming sticks plugged into television sets around the globe. But upon inspecting the traffic being funneled to the domain, he discovered nearly all of the TV boxes transmitting data claimed to be mobile phone models from a variety of manufacturers, including Samsung, Vivo, Huawei, and Xiaomi. “We noticed something was wildly wrong,” Falé said. “Multiple devices reporting to this factory Android TV Box backdoor were ‘phones.'” The researcher found all of the devices reported having the same two apps installed, and that those apps were made by a company called Zhejiang Fengwo IoT Technology Ltd, an entity founded in 2019 in mainland China which operates an ad-publishing portfolio under the name Fengwo Group. Further investigation into the Fengwo Group revealed it has registered multiple patents that match the inner workings of these apps. “Bitsight TRACE identified several Hong Kong, Singapore, and single person ‘legal’ shell identities used to collect the monetization and traced the operation back to a mainland China company known as Zhejiang Fengwo IoT Technology Co., Ltd, which operates under the Fengwo Group,” Falé wrote in a report released today about their findings. Falé said an analysis of the apps shows they help to coordinate an ad fraud network that uses these H96 devices as a captive traffic source to click on ads at AI-generated websites operated by the Fengwo Group. Bitsight discovered the websites contain machine-generated news articles and graphics across a range of categories, including finance, health, education, gaming, music and food blogs. But they also found none of those sites displayed ads unless the device visiting the page matched the spoofed mobile profile of these H96 devices.
