Security researchers from XLab have uncovered a new and more dangerous variant of the Vo1d botnet, a long-running malware operation that has now compromised more than 1.6 million Android TV devices across multiple regions. Vo1d hijacks these devices, transforming them into remotely controlled bots that cybercriminals use for large-scale attacks and fraudulent activities. The latest iteration of the botnet introduces stronger encryption to prevent security experts from intercepting and analyzing its commands, alongside improved stealth techniques that make detection more difficult.
Infected Android TV devices within the Vo1d network are exploited for two primary cybercriminal activities. First, they participate in Distributed Denial of Service (DDoS) attacks, where the botnet floods targeted websites or services with excessive traffic, rendering them inaccessible. Second, the botnet engages in ad click fraud, where compromised devices generate fake ad clicks to manipulate digital advertising revenue. While Vo1d operates globally, the majority of infections have been reported in Argentina, Brazil, China, Indonesia, South Africa, and Thailand, highlighting specific regional vulnerabilities.
To mitigate the risk of infection, users should take proactive security measures when purchasing and using an Android TV device. Buying from reputable brands and authorized sellers can help avoid pre-installed malware, which may be embedded at the manufacturing or distribution stage. Keeping firmware and security updates up to date is essential, as software patches often contain critical fixes for vulnerabilities that cybercriminals exploit. Lastly, users should exclusively install apps from the Google Play Store, avoiding third-party marketplaces that may host malicious applications. Following these steps can help ensure that Android TV devices remain secure and free from botnet threats.
