Malware Attack on Android TV Devices Affects Over 1.6 Million Users

 



Cybersecurity researchers have discovered a new form of malware that is spreading through Android TV devices across the globe. This malware, known as Vo1d, has already infected over 1.6 million devices, turning them into remote-controlled bots used for illegal activities without the owners’ knowledge.  

The Vo1d malware has existed for a while, but researchers at XLab recently identified a stronger, more advanced version that makes it harder to detect and remove. This upgraded variant has been designed to avoid being analyzed or controlled by cybersecurity experts, making it a serious concern for Android TV users.  


How the Vo1d Malware Works  

Once Vo1d malware enters an Android TV device, it secretly connects it to a network controlled by hackers, known as a botnet. This allows the attackers to control thousands of devices at once without the owners realizing it. These devices are then used to carry out illegal activities like DDoS attacks and ad click fraud.  

In a DDoS (Distributed Denial of Service) attack, a large number of devices flood a website or service with so many requests that it crashes, making it inaccessible. On the other hand, ad click fraud involves the infected devices automatically clicking on online ads, creating fake revenue for dishonest advertisers. Both of these activities can cause financial losses to companies and harm online platforms.  

The malware has been particularly active in countries like Argentina, Brazil, China, Indonesia, South Africa, and Thailand. However, since it is spreading rapidly, users in other countries should also remain cautious.  


Why This Malware Is Difficult to Detect  

One of the main challenges with the new Vo1d variant is that it uses advanced encryption methods, which prevent cybersecurity professionals from studying or controlling it. It also hides deep within the device’s system, making it nearly impossible for regular antivirus software to detect and remove it.  

This ability to stay hidden allows the malware to operate silently for long periods, allowing hackers to keep using the device for illegal purposes. As a result, users may remain unaware that their device has been compromised.  


How to Protect Your Android TV Device  

To reduce the chances of your Android TV being infected by Vo1d, consider following these precautionary steps:  

1. Buy From Trusted Sources: Always purchase Android TV devices from well-known brands or official retailers. Avoid buying from unknown sellers, as some devices may already be compromised before purchase.  

2. Update Regularly: Install all firmware and security updates provided by the device manufacturer. These updates often fix vulnerabilities that malware exploits.  

3. Download Apps Carefully: Only download apps from official platforms like the Google Play Store. Avoid installing apps from third-party websites, as they may carry hidden malware.  

4. Watch for Unusual Activity: If your Android TV starts slowing down, overheating, or using too much data without reason, it may be infected. In such cases, reset your device and consider installing a trusted antivirus app.  

5. Secure Your Network: Make sure your home Wi-Fi has a strong password and activate firewall settings to reduce the chances of remote attacks.    


The rapid spread of Vo1d malware has raised concern among cybersecurity experts. With over 1.6 million devices already infected, users need to stay alert and take protective measures. By purchasing devices from verified sources, keeping software updated, and avoiding untrusted apps, users can reduce their risk of falling victim to such malware attacks.  

Staying informed about new threats and remaining cautious with device usage is the best way to keep your Android TV safe from harmful malware like Vo1d.

Android TV Users Watch Out: Dangerous Vo1d Botnet Hits 1.6 Million Devices

Android TV Users Watch Out: Dangerous Vo1d Botnet Hits 1.6 Million Devices

Hackers are upping their game, getting better through attacks and strategies. The latest incident of this rise is the disturbing spread of the Vo1d malware botnet. Vo1d is a highly sophisticated malware and infected around 1,590,299 Android TV devices throughout 226 countries, changing them into “anonymous proxy servers" for malicious activities. 

Why is Vo1d malware so dangerous?

Vo1d is considered dangerous because of its persistence and potential to expand despite earlier discoveries by cybersecurity experts.

Research by Xlab suggests Void had 800,000 active bots, “Peaking at 1,590,299 on January 14, 2025.” Experts believe the botnet is being rented to hacking groups for various illegal activities, from escaping regional internet restrictions to ad frauds. 

Vo1d’s campaign trend suggests that the devices are leased out and then returned, causing a sharp rise and fall in the number of active bots in particular regions. The highest impact has been noticed in South Africa, Argentina, Brazil, China, and Thailand.

About Vo1d Malware 

Vo1d is not your average Joe, it is one of the most advanced and biggest malware in recent years, outperforming deadly botnets such as Bigpanzi and Mirai. Its Command and Control (C2) framework uses 2048-bit RSA encryption and Domain Generation Algorithms, making it indestructible. Vo1d uses 32 DGA seeds to create over 21,000 C2 domains, making it operational despite attempts to close its network.

It transforms infected devices into proxy servers, allowing threat actors to reroute malicious traffic via infected devices, hiding their source location and escaping detection. 

The proxies are then used for various illegal activities such as:
  1. Illegal Transactions
  2. Security evasion 
  3. Advertising Frauds

What makes Vo1d even more dangerous is its evolving nature

V01d is considered a severe threat due to its “evolving nature”. According to Forbes, the “latest version includes enhanced stealth capabilities and custom XXTEA encryption, further complicating detection and removal efforts.” In case researchers can register a C2 domain, they “can’t issue commands to disable the botnet due to the strong encryption measures in place."

The malware also uses special plugins like Mzmess SDK, used for ad-clicking scams. The SDK allows the botnet to mimic “human-like” interface, scamming advertising networks into payments. Vo1d can also harvest system data such as IPs, device specs, and network info from compromised devices. This can trigger further attacks. 

Evolution of Vo1d malware

Another important highlight about Vo1d’s expansion is its attack strategy. Although the experts don't know the infection vector, they believe the malware distributes via harmful firmware updates, Android TV system vulnerabilities, or sideloaded apps. Experts also suspect that illegal streaming services and infected third-party app stores may contribute to spreading the malware.

Tips to Stay Safe

IoT and Android TV users should follow these precautions to lower the chances of attacks:
  1. Update update update! Hackers exploit vulnerabilities in outdated software. 
  2. Buy IoT devices and Android TV from authorised manufacturers. Avoid third party sellers. 
  3. Disable “remote access” (if enabled) on your Android TV and IoT device, unless absolutely needed. 
  4. Only install apps from Google Play Store. Avoid installing apps from third-party.
  5. Disconnect inactive devices from the internet, if not in use.
  6. Use a network monitoring tool to identify malicious internet traffic patterns and find out about a compromised device.

Users should be more careful

Xlab warns about the dangers of Vo1d malware, “Many users harbor misconceptions about the security of TV boxes, deeming them safer than smartphones and thus rarely installing protective software.” 

Higlighting the dangers of using modded apps and software, Xlab says the “widespread practice of downloading cracked apps, third-party software, or flashing unofficial firmware—often to access free media—greatly increases device exposure, creating fertile ground for malware proliferation.”
