## Key points

- Millions of Android devices, primarily TV boxes, are compromised by a pre-installed firmware backdoor enabling remote control and data exfiltration.
- Videostrong and MECOOL-branded Android TV boxes, telehealth, karaoke, and digital signage devices contain the persistent x.cpe backdoor.
- Infected devices must be disconnected and replaced, as the x.cpe backdoor cannot be removed by users or factory resets.

## Google Disrupts x.cpe [Botnet](/glossary#botnet) Affecting Millions of Android Devices

### Overview of the x.cpe Botnet Disruption

Google has spearheaded a major takedown operation, disrupting a vast botnet comprising over 1.3 million Android devices, predominantly Android TV set-top boxes. This sophisticated campaign, which saw its command-and-control ([C2](/glossary#c2)) servers dismantled in late October, has been attributed by Google to device manufacturer Videostrong. According to [The Hacker News](https://thehackernews.com/2026/11/google-disrupts-13-million-device.html), Google is highly confident that Videostrong intentionally embedded a [backdoor](/glossary#backdoor), dubbed 'x.cpe', into its devices and sold access to this functionality to criminal elements. These actors leveraged the compromised devices for purposes such as ad fraud and operating residential proxy services, routing illicit traffic through unsuspecting owners' home internet connections. While the C2 infrastructure has been neutralized, the underlying `x.cpe` backdoor remains embedded within the devices' [firmware](/glossary#firmware), posing a persistent threat that users cannot easily remove.

### Technical Analysis of the x.cpe Backdoor

The `x.cpe` backdoor operates as a system application deeply integrated into the device firmware, granting it system-level access. Google's analysis reveals that this backdoor reports to its C2 servers, awaiting instructions. A key malicious capability of `x.cpe` is its ability to silently install software by first disabling Google Play Protect's app verification checks. Through this backdoor, botnet operators gained extensive control, including the capacity to install unauthorized applications, execute commands, capture screen content, map local networks, and open reverse shells for remote command-line access. Google observed Videostrong's operators exploiting these capabilities to capture live screenshots, send keystrokes, exfiltrate account details, device information, app lists, and system logs. The criminal modules loaded via `x.cpe` primarily repurposed devices into residential proxies or ad fraud machines, generating fake views for online advertisements. Beyond Android TV boxes, the backdoor was also found on telehealth devices, karaoke machines, and digital signage, broadening the scope of affected systems.

### Videostrong's Alleged Role and Scope of Compromise

Google's investigation strongly implicates Videostrong, a Shenzhen, China-based manufacturer, in the creation and distribution of the `x.cpe` backdoor. Evidence includes a document signed by Videostrong's R&D director found on a botnet server and a Videostrong web domain sharing an IP address with the operators' control panel. Videostrong manufactures devices under its own name and for other brands, notably MECOOL. The backdoor has been present in various models and brands over several years. TrendAI, an enterprise unit of Trend Micro, identified over 1.47 million infected devices across 206 models between June and October, with actual numbers likely higher. Geographically, Malaysia, Brazil, Iraq, Mexico, and Taiwan saw the most infections, while the U.S., Germany, the U.K., Australia, and Canada each had tens of thousands of compromised devices. Google has severed ties with Videostrong, banning the company and its affiliates from manufacturing or selling certified Android devices. Google also stated that Videostrong deliberately bypassed certification tests by loading malicious code after initial device boot, prompting changes to Google's review processes and firmware checks for certified Android TV devices.

### Actionable Recommendations for x.cpe Backdoor Detection and Mitigation

Due to the firmware-embedded nature of `x.cpe`, detection and removal present significant challenges. The backdoor reinstalls itself upon device restart, rendering factory resets ineffective against the core compromise. TrendAI advises that cleanup requires "vendor action, platform protection or replacement of the device." Synthient, a cybersecurity firm involved in the takedown, goes further, recommending consumers discard these boxes entirely due to the high risk of persistent [malware](/glossary#malware). For organizations managing remote staff, TrendAI suggests treating unmanaged consumer devices on home networks as part of the [attack surface](/glossary#attack-surface), emphasizing secure corporate access via managed devices only.

To effectively address **mitigation for pre-installed firmware backdoors** like `x.cpe`, the primary recommendation is to replace any identified **Videostrong Android TV box security risks** or MECOOL-branded devices suspected of harboring the backdoor. There is currently no reliable method for users to remove the `x.cpe` backdoor from affected devices. Organizations should review their hardware procurement policies to prevent the introduction of unvetted or suspicious devices into their environments, especially those that might be susceptible to **x.cpe backdoor detection and removal** difficulties. Implementing [network segmentation](/glossary#network-segmentation) and monitoring for unusual outbound traffic patterns can also help identify and isolate compromised devices, even if the backdoor itself cannot be eradicated.
