XCPE Botnet: How a Backdoored Android OEM Turned 1.3 Million IoT Devices Into Criminal Infrastructure
In November 2026, Google's Threat Intelligence Group and industry partners disrupted the XCPE botnet, a supply-chain backdoor operation attributed with high confidence to Android device manufacturer Videostrong Technology Co. Beginning at least in 2024, Videostrong allegedly embedded the XCPE backdoor into firmware across more than 1.3 million Android-based set-top boxes, telehealth devices, karaoke machines, and digital signage systems. Criminal affiliates purchased access to the compromised fleet, deploying modules for ad fraud, residential proxy enrollment, credential theft, keystroke injection, screenshot capture, and reverse-shell establishment. Disruption of the affiliate command-and-control infrastructure is expected to sever access to an additional 10 million compromised devices globally. The XCPE campaign illustrates a maturing threat model in which the hardware supply chain itself becomes the initial compromise vector, bypassing traditional perimeter controls entirely. As IoT device proliferation accelerates across healthcare, retail, and enterprise environments, attackers are increasingly targeting OEM firmware pipelines to pre-position persistent access at scale before devices ever reach end users.
