Today's digital landscape is marked by increasing use of mobile devices and greater concern about privacy protection. However, this trend has also led to an alarming expansion of malware on Androidspecifically of Apps that disguise themselves as VPN services legitimate and can put both your device and your digital privacy at risk. If you have any of these malicious VPN apps installed on your Android phone, it's a priority to remove them as soon as possible.
These aren't just threats detected in external repositories or unofficial stores: many of these apps have even managed to sneak into the Google Play Store itself, deceiving both users and Google's review systems. Although they may appear legitimate and offer attractive free services, the reality is very different: they can turn your smartphone into a node of a malicious proxy network, spy on your personal data, or even facilitate large-scale attacks against your privacy and your digital economy.
In this article we explain How malware disguised as a VPN works on Android, why it's proliferating so much even in official stores, which apps have been identified as dangerous, and how to effectively protect yourself, integrating all the relevant and practical information you need to know to navigate safely through the Android ecosystem.
The rise of Android malware and the role of VPN apps
Security threats on Android have evolved rapidly in recent years. cybercriminals They have sophisticated techniques to circumvent the security controls of official stores and exploit the growing interest in digital privacy to distribute fraudulent applications under the guise of free VPNs.
The statistics speak for themselves: recent reports have detected increases of up to 89% of incidents related to fraudulent VPN apps compared to previous years, according to firms like Kaspersky. These applications appear to protect users, but in reality, they compromise their security, turning devices into proxy servers for illicit activities such as fraud, identity theft, cyberattacks, and the exploitation of personal data.
In the particular case of Android, the ease of app publishing, the popularity of the system, and the trust in the Play Store have facilitated the spread of malicious apps. Those affected can lose control over their banking information, browsing history, or passwords without even realizing it, especially if the app in question operates silently behind a legitimate appearance.
Why is there so much malware on Google Play?
If you're wondering how malicious apps can end up on Google Play, the answer involves both advances in social engineering and limitations in review mechanisms. Although Google implements automated and human filters and reviews, there are several tactics that malware developers have perfected to go undetected:
- Publishing seemingly legitimate apps that, after gaining popularity, are updated with malicious code in subsequent versions.
- Sale and purchase of applications already established in the deep web, to subsequently modify its code and add harmful functions without alerting loyal users.
- Updates disguised as “security enhancements” or “special offers” actually introduce hidden features that steal data or open access to criminal networks.
The result is that even when installing apps from the Play Store, there's a risk of your device being compromised, especially if the apps rack up thousands of downloads before being detected by digital security authorities.
How malicious VPN apps work on Android
Authentic VPN apps offer traffic encryption and hide the user's IP address, providing privacy from internet providers, advertisers, or potential spies. However, when the VPN is malicious or manipulated, just the opposite happens: your traffic can be intercepted, your data sold, or your device turned into a residential proxy server that channels criminal activities without your consent.
This happens in several ways:
- The infected phone becomes a sort of "bridge" for other cybercriminals' illicit traffic, making it difficult to trace the true source of DDoS attacks, ad fraud, or credential theft, as connections will appear to originate from common residential IP addresses.
- Users may be unfairly investigated or held accountable for crimes they did not commit simply for serving as a gateway for activities such as phishing, attacks on banks, or unauthorized access to third-party accounts.
- In more advanced cases, malicious apps can also collect data such as contacts, SMS messages, chat content, location, call logs, and even record phone conversations or access files stored on the device.
Botnets made up of infected devices (such as the notorious 911 S5 network) have grown to include millions of IP addresses worldwide, generating large-scale coordinated attacks, money laundering, and massive fraud campaigns.
Notable cases of malicious VPN apps and how they operate
There have been numerous reports and alerts from cybersecurity firms identifying VPN apps as dangerous on Android. Below, we explain the techniques used by different actors and specific examples documented by international authorities:
- Malware Proxy or Botnet: Apps like MaskVPN, DewVPN, PaladinVPN, and ShineVPN have been specifically flagged for creating a network of proxy servers from infected devices, facilitating illicit activities such as money laundering, DDoS, and phishing.
- Personalized espionage: Groups like APT Bahamut have launched highly targeted campaigns using trojanized versions of VPN apps (SoftVPN, OpenVPN, SecureVPN), which collect personal data and spy on messaging apps (WhatsApp, Telegram, Facebook Messenger, Signal, Viber, WeChat, among others).
- Commercialization of private data: According to studies by universities and security labs, up to 84% of free VPN apps analyzed collect user traffic, and 38% contain some type of malicious component. Many of these apps sell your data to commercial brokers or share it with social networks and advertisers.

Main risks of malicious VPNs on Android
- Theft of sensitive information: Passwords, banking information, social media login credentials, and email addresses can be intercepted and sent to remote servers controlled by cybercriminals.
- Converting your mobile into a proxy server: Any illegal activity (from fraud to attacks on other services) may appear to have been carried out from your IP address.
- Exposure to coordinated cyberattacks: Your device may be part of a botnet used to launch DDoS attacks or large-scale ad fraud.
- Marketing of your data: Many “free” apps profit from access to your privacy by selling location data, browsing history, and even usage patterns to advertising companies or data brokers.
How to choose a secure VPN for Android?
The proliferation of fraudulent apps doesn't mean we should give up on VPN services on Android, but we should be extremely cautious. To choose a safe VPN, consider the following factors:
- Choose services from recognized companies, with a proven track record and good reviews in specialized media. Be wary of apps with few votes, negative reviews, or newcomers to the market.
- Avoid 100% free VPNsCheap things often end up being expensive: if you're not paying with cash, you're probably paying with your data.
- Review the requested permissionsDon't install a VPN that demands full access to your contacts, SMS, camera, microphone, or location without justification.
- Read independent reviews and check out the list of safe apps, such as the one from the , which compiles audited and malware-free services.
- Keep your operating system and apps updated. The updates address vulnerabilities that can be exploited by malware.
- Use complementary security solutions (trusted antivirus and privacy monitoring services) to detect emerging threats before they become a problem.
How to protect yourself from malicious apps on Android and key recommendations
- Always download from official sources. While the Play Store isn't foolproof, it's still less risky than unofficial stores or websites of dubious origin.
- Monitor the permissions granted. If a VPN app requests access to elements outside its scope, be wary and look for more transparent alternatives.
- Update passwords and monitor access. If you've used any of the identified malicious apps, immediately change your passwords and review the login logs for your important accounts (banking, email, social media).
- Rely on security tools: Install an updated mobile antivirus and enable features such as periodic scanning for suspicious apps and connections.
- Make regular backups. This way you will minimize the impact of a possible incident.
- Disable and delete unnecessary apps. The fewer apps you have installed, the smaller the attack surface and the more control you'll have over your device.
Advanced Threats: VPN Trojans and Espionage Campaigns
In addition to "commercial" malware and organized crime, there are advanced cyber espionage groups such as the one already mentioned. APT Bahamut, which have targeted specific attacks using Trojanized VPN apps outside of Google Play. These attacks can be undetectable by most antivirus software and employ additional layers of protection, such as requiring activation keys sent to specific targets (for example, through phishing or social engineering campaigns).
The way these apps work is extremely dangerous:
- They are distributed through fake websites that imitate legitimate brands.
- They include spy code capable of collecting contacts, messages, locations, recording calls, and monitoring chats in real time.
- They exfiltrate all information to control servers that can be located anywhere in the world, making attribution and response difficult.
Therefore, even the most experienced users can fall victim if they stumble upon obscure areas outside the Play Store or interact with unknown links in emails, social media, or direct messages that promise free premium services.
Indicators of compromise and symptoms of infection
- Noticeable decrease in speed or battery life of your device.
- Unexpected spikes in mobile data or WiFi traffic.
- Presence of unknown apps or changes to common apps without your consent.
- Appearance of ads or redirects to suspicious websites.
- Repeated permission requests or unusual pop-up messages.
If you notice any of these symptoms, perform a security scan, uninstall suspicious apps, and change all passwords. If the problem persists, consider restoring your device to factory settings after backing up.
Common mistakes users make when installing free VPN apps
- Relying on an app's presence in official stores and not investigating its permissions, owner, or privacy policy.
- Looking for the cheapest or free option without reading independent reviews or consulting specialized sources.
- Allow all requested permissions for convenience, which gives apps full control over critical device functions.
- Do not update the operating system or apps, which leaves the phone exposed to known vulnerabilities.
- Not having a comprehensive security solution that detects anomalous behavior in real time.
The importance of digital awareness and education
Recommendations from international organizations and cybersecurity companies emphasize the need to train users so they can distinguish between legitimate and fraudulent apps, understand how personal data is traded, and how to protect themselves from emerging threats in the Android environment.
Whenever you download a new app, do your research:
- Who is the developer and what is his track record?
- What permissions does the app actually request?
- What other users and security experts think about the product.
- Whether there are independent reports or public security audits on the application.
What to do if you've been a victim of a malicious VPN app?
- Immediately uninstall any suspicious apps.
- Run a full scan with a trusted security solution.
- Change all your important passwords from one secure device.
- Enable two-step verification for your critical services.
- Consult with technical support or official cybersecurity helplines if you suspect your data may have been leaked or if you experience unauthorized activity on your accounts.
Additional tips to protect your privacy on Android
- Use strong and unique passwords for each platform.
- Enable two-step authentication when available.
- Do not share your credentials on unreliable platforms or services.
- Periodically review the installed apps and delete those you no longer use.
- Avoid linking banking services or social networks to apps whose origin or reputation you don't know.
Security and privacy in the Android environment are a shared responsibility. Choosing apps wisely, actively monitoring permissions and download sources, and using effective security tools can make the difference between safe digital use and the risk of falling victim to fraud, spying, and losing important data. By following these recommendations and maintaining a cautious attitude, you can enjoy the benefits of the Android ecosystem without compromising your privacy or the integrity of your device.
