We usually think of cyberattacks as something that begins with a suspicious email, a malicious download, or a compromised password.
But what if the device responsible for your next cyberattack is already sitting in your living room?
In November 2026, Google and several cybersecurity partners announced the disruption of XCPE, a botnet that had compromised more than 1.3 million Android TV set-top boxes across the world.
The concerning part wasn't simply the scale of the attack. It was how these devices became compromised in the first place: malicious software was embedded into devices before they even reached consumers.
This incident highlights a growing cybersecurity problem that deserves more attention: the security of connected devices begins long before users switch them on.
1. What Happened? Understanding the XCPE Botnet
According to Google's Threat Intelligence Group (GTIG), the XCPE botnet was associated with Videostrong Technology Co., an Android device manufacturer.
Rather than relying on users to download malicious applications or click suspicious links, the malware was incorporated into the device ecosystem before the products reached their owners.
Once connected to the internet, compromised devices could communicate with remote infrastructure and receive additional malicious modules.
Researchers identified several ways these devices were monetised:
- Residential proxy networks: Users' internet connections and IP addresses were secretly made available to third parties.
- Advertising fraud: Compromised devices participated in activities designed to generate fraudulent advertising revenue.
- Additional malware distribution: Devices could receive further malicious software modules.
- Remote access: The compromised infrastructure provided operators with capabilities to interact with infected devices.
In other words, an ordinary streaming device could become part of a criminal infrastructure without its owner knowing anything about it.

2. How Does a Residential Proxy Botnet Work?
One of the most interesting aspects of this incident is the abuse of residential proxy networks.
A residential proxy routes internet traffic through an actual residential IP address instead of a conventional data-centre IP.
These services have legitimate use cases, including regional testing, market research, and accessing geographically restricted content.
However, when devices are enrolled without their owners' consent, the same infrastructure becomes an attractive resource for cybercriminals.
Consider this simplified attack flow:
- A consumer purchases an Android TV box.
- The device contains pre-installed malicious components.
- Once connected to the internet, the malware communicates with its command-and-control infrastructure.
- Additional modules are installed on the compromised device.
- The device's residential IP address and internet bandwidth become available to external operators.
- Third parties can use the compromised network for activities such as automated traffic, advertising fraud, and other malicious operations.
The dangerous part is that the device may continue functioning normally.
Your streaming experience might remain unchanged while your internet connection is being used for activities you never authorised.
3. Why Is This a Supply Chain Security Problem?
Traditional endpoint security often focuses on protecting devices after deployment.
We install antivirus software, configure firewalls, apply patches, and monitor suspicious activity.
But XCPE demonstrates a different problem.
What happens when the device is already compromised before the customer receives it?
This is a hardware and software supply chain security issue.
A manufacturer controls several critical stages of the device lifecycle:
- Firmware development and compilation.
- Pre-installed applications and system services.
- Software signing and update mechanisms.
- Third-party SDK integrations.
- Device certification and distribution.
If malicious functionality enters during these stages, conventional security practices may not be sufficient.
Even a device carrying familiar Android branding or certification can present security risks if the underlying implementation and update process are compromised.
This also raises an important question for organisations purchasing connected devices:
Are we evaluating only the device specifications, or are we evaluating the security practices of the manufacturer?
4. The Bigger Concern: Your IoT Device Is Also a Network Entry Point
The XCPE incident was not limited to television set-top boxes.
Google's investigation identified the same malware in other Android-based IoT products, including:
- Telehealth devices.
- Karaoke machines.
- Digital signage systems.
This makes the incident particularly relevant to organisations deploying connected hardware.
Imagine an infected IoT device connected to a corporate or healthcare network.
Even if the original compromise is limited to the device, its network connectivity could create opportunities for further malicious activity.
A poorly segmented network can make the situation considerably worse.
This is why IoT security should not be treated as an isolated endpoint problem.
It should be part of the organisation's broader network security strategy.
5. How Was the XCPE Botnet Disrupted?
In November 2026, Google worked with several industry partners, including:
- Plume
- Trend Micro (TrendAI)
- Lumen
- HUMAN Security
- Synthient
- Japan's National Police Agency
The coordinated operation targeted the infrastructure supporting the botnet.
Google reported taking legal action to disrupt domains and servers used by Videostrong to control the malware and distribute additional modules.
The operation also targeted command-and-control infrastructure associated with criminal affiliates.
According to Google's assessment, disrupting these systems could sever access to at least 10 million additional compromised devices.
It is important to understand that disrupting command-and-control infrastructure is not necessarily the same as removing malware from every infected device.
This distinction matters because compromised devices may retain malicious components even after the operators lose control of their infrastructure.
The incident therefore demonstrates why threat disruption and endpoint remediation must go hand in hand.
6. What Can Users and Organisations Learn From This Incident?
The XCPE incident provides several practical security lessons.
For individual users:
- Purchase connected devices from reputable manufacturers with transparent security practices.
- Research device models and check whether they have known security issues.
- Keep device firmware and software updated.
- Avoid connecting untrusted IoT devices to networks containing sensitive systems.
- Monitor unusual network activity and unexpected bandwidth consumption.
For organisations and network administrators:
- Maintain an inventory of all connected IoT devices.
- Implement network segmentation to isolate untrusted devices.
- Monitor outbound connections and unusual traffic patterns.
- Restrict unnecessary communication with external command-and-control infrastructure.
- Evaluate manufacturers' firmware security and software update policies.
- Establish incident response procedures for compromised IoT hardware.
One particularly important recommendation is to avoid assuming that a factory reset will remove firmware-level or system-level malware. Organisations should follow manufacturer security advisories and use verified remediation or replacement procedures where necessary.
7. The Bigger Lesson: Trust Must Start at the Hardware Level
For years, cybersecurity conversations have focused heavily on applications, operating systems, passwords, and network infrastructure.
But the XCPE incident reminds us that security cannot begin only after a device enters the customer's network.
It must begin during manufacturing, firmware development, software distribution, and the entire device lifecycle.
The most concerning cyberattacks are not always the ones that immediately disrupt a service or display a ransomware message.
Sometimes, the most effective compromise is the one that remains invisible while quietly turning millions of ordinary devices into infrastructure for someone else's business.
A smart device should make our lives easier, not turn our homes into infrastructure for cybercriminals.
The next time you purchase an inexpensive Android TV box or another connected device, it is worth asking a question beyond its specifications:
Do I actually trust the software running inside it?
