Over 1.3 million TV set-top boxes came with a built-in backdoor, Google says

Checked

Google took down the botnet and banned the maker, but the backdoor stays on infected boxes. Check certification and unplug any box you can't vouch for.

Who is affected

People who own Android TV set-top boxes (streaming boxes that plug into a TV), especially low-cost or off-brand ones. Google says the malicious software was "built directly into many different device models and brands over multiple years," and that most infected devices were Android TV set-top boxes, with some telehealth devices, karaoke machines and digital signs too (Google Threat Intelligence). Google does not list the consumer brands or models, so there is no official list to check your box against. The report is about TV boxes and similar gadgets, not phones.

What happened

On November 2, 2026, Google reported that it and industry partners had dismantled a botnet it calls XCPE the week before. Google says, with high confidence, that the device maker Videostrong Technology Co. deliberately built a backdoor into its boxes and sold access to criminal affiliates. Google says the backdoor pulled more than 1.3 million set-top boxes into a botnet. The affiliates' software used infected boxes for ad fraud, turned them into residential proxies (so strangers' internet traffic ran through owners' home connections), and loaded more malware. Google also saw the maker's own operators take data such as account and device information. All of this happened without owners' knowledge or consent (Google Threat Intelligence). Google took legal action to take down the servers that controlled the botnet, cut ties with Videostrong, and banned it from building certified Android devices or supplying software to certified makers. Google says this maker got past its compatibility and security tests by loading the malicious code after the device's first startup, and it has changed its review process (Google Threat Intelligence, CyberScoop). We aren't sharing technical details of the malware.

The control servers are down, but the software is still on infected boxes. It is built into the box's firmware (the box's core software) and reinstalls itself if removed, so cleaning it takes clean firmware, or the box should be disconnected from the internet (BleepingComputer). Owners can't remove it themselves; cleanup needs action from the maker, platform protection, or replacing the device (TrendAI).
