Videostrong preloaded an Android TV backdoor in device firmware that automatically reinstalls itself after users uninstall it, researchers at Google Threat Intelligence Group say. The persistent software enrolled more than 1.3 million set-top boxes in a financially motivated botnet.

The preloaded package, x.cpe, runs at android.uid.system privilege and restores itself from the /oem/ partition on reboot. It disables Google Play Protect and holds a persistent MQTT command channel for silent app installs, shell commands, screen captures and network reconnaissance. Operators monetized infected devices as residential proxies and ad-fraud engines; non-TV Android IoT victims included telehealth devices, karaoke machines and digital signage.

Google and industry partners dismantled the botnet, took legal action against its C2 domains and servers and against C2 domains for over a dozen affiliate malware families, and banned Videostrong from certified Android devices. Google says the takedown is assessed to sever access to at least 10 million additional compromised devices and has improved firmware-integrity reviews for certified Android TV hardware.
