Tracing the footprints of Virtual Invaders

ESET researchers have discovered an active espionage campaign targeting Android users with apps primarily posing as messaging services. While these apps offer functional services as bait, they are bundled with open-source XploitSPY malware. We have named this campaign eXotic Visit and have tracked its activities from November 2021 through to the end of 2023. The targeted campaign has been distributing malicious Android apps through dedicated websites and, for some time, through the Google Play store as well. Because of the targeted nature of the campaign, the apps available on Google Play had a low number of installs; all of them have been removed from the store. The eXotic Visit campaign appears to primarily target a select group of Android users in Pakistan and India. There is no indication that this campaign is linked to any known group; however, we are tracking the threat actors behind it under the moniker Virtual Invaders.

Key points of the report:

  • This active and targeted Android espionage campaign, which we have named eXotic Visit, started in late 2021 and mainly impersonates messaging apps that are distributed through dedicated websites and Google Play.
  • Overall, at the time of writing, around 380 victims have downloaded the apps from both sources and created accounts to use their messaging functionality. Because of the targeted nature of the campaign, the number of installs of each app from Google Play is relatively low – between zero and 45.
  • Downloaded apps provide legitimate functionality, but also include code from the open-source Android RAT XploitSPY. We have linked the samples through their use of the same C&C, unique and custom malicious code updates, and the same C&C admin panel.
  • Throughout the years, these threat actors have customized their malicious code by adding obfuscation, emulator detection, hiding of C&C addresses, and use of a native library.
  • The region of interest seems to be South Asia; in particular, victims in Pakistan and India have been targeted.
  • Currently, ESET Research does not have enough evidence to attribute this activity to any known threat group; we track the group internally as Virtual Invaders.

Apps that contain XploitSPY can extract contact lists and files, get the device’s GPS location and the names of files listed in specific directories related to the camera, downloads, and various messaging apps such as Telegram and WhatsApp. If certain filenames are identified as being of interest, they can subsequently be extracted from these directories via an additional command from the command and control (C&C) server. Interestingly, the implementation of the chat functionality integrated with XploitSPY is unique; we strongly believe that this chat function was developed by the Virtual Invaders group.

The malware also uses a native library, which is often used in Android app development for improving performance and accessing system features. However, in this case, the library is used to hide sensitive information, like the addresses of the C&C servers, making it harder for security tools to analyze the app.

The apps described in the sections below were taken down from Google Play; moreover, as a Google App Defense Alliance partner, ESET identified ten additional apps that contain code that is based on XploitSPY and shared its findings with Google. Following our alert, the apps were removed from the store. Each of the apps described below had a low number of installs, suggesting a targeted approach rather than a broad strategy. The Timeline of eXotic Visit apps section below describes the “fake”, albeit functional, apps we have identified as part of this campaign, whereas the Technical analysis section focuses on the details of the XploitSPY code, present in various incarnations across those apps.

Timeline of eXotic Visit apps

Starting chronologically, on January 12th, 2022, MalwareHunterTeam shared a tweet with a hash and a link to a website that distributes an app named WeTalk, which impersonates the popular Chinese WeChat application. The website provided a link to a GitHub project to download a malicious Android app. Based on the date available on GitHub, the wetalk.apk app was uploaded in December 2021.

At that time, there were five apps available, using the names ChitChat.apk, LearnSindhi.apk, SafeChat.apk, wechat.apk, and wetalk.apk. The ChitChat app had been available on GitHub since November 2021, distributed using a dedicated website (chitchat.ngrok[.]io; see Figure 1) as well as the malicious WeTalk app mentioned earlier. Both use the same C&C address with the admin panel login interface shown in Figure 2.

Figure 2. Admin panel login page for the WeTalk and ChitChat C&C server
Figure 2. Admin panel login page for the WeTalk and ChitChat C&C server

Since July 2023, the same GitHub account has hosted new malicious Android apps that have the same malicious code and C&C server. We don’t have any information on how these apps are distributed. Apps are stored in five repositories, using names such as ichat.apk, MyAlbums.apk, PersonalMessenger.apk, Photo Collage Grid & Pic Maker.apk, Pics.apk, PrivateChat.apk, SimInfo.apk, Specialist Hospital.apk, Spotify_ Music and Podcasts.apk, TalkUChat.apk, and Themes for Android.apk.

Returning to ChitChat.apk and wetalk.apk: both apps contain the promised messaging functionality, but also include malicious code we have identified as the open-source XploitSPY available on GitHub. XploitSPY is based on another open-source Android RAT called L3MON; however, it was removed from GitHub by its author. L3MON was inspired by yet another open-source Android RAT named AhMyth, with extended functionality (we covered another AhMyth-derived Android RAT in this WeLiveSecurity blogpost).

Espionage and remote control of the targeted device are the main purposes of the app. Its malicious code is capable of:

  • listing files on the device,
  • sending SMS messages,
  • obtaining call logs, contacts, text messages, and a list of installed apps,
  • getting a list of surrounding Wi-Fi networks, device location, and user accounts,
  • taking pictures using the camera,
  • recording audio from the device’s surroundings, and
  • intercepting notifications received for WhatsApp, Signal, and any other notification that contains the string new messages.

The last function might be a lazy attempt to intercept received messages from any messaging app.

The same C&C address that was used by previously mentioned apps (wechat.apk and ChitChat.apk) is also used by Dink Messenger. Based on VirusTotal’s in-the-wild URLs, this sample was available for download from letchitchat[.]info on February 24th, 2022. That domain was registered on January 28th, 2022. On top of messaging functionality, the attackers added malicious code based on XploitSPY.

On November 8th, 2022, MalwareHunterTeam tweeted a hash of the malicious Android alphachat.apk app with its download website. The app was available for download on the same domain as the Dink Messenger app (letchitchat[.]info). The Alpha Chat app uses the same C&C server and C&C admin panel login page as in Figure 2, but on a different port; the app also contains the same malicious code. We don’t have information about when Dink Messenger was available on the domain; subsequently, it was replaced by Alpha Chat.

The trojanized Alpha Chat app, compared to previous versions of XploitSPY from the eXotic Visit campaign, contains a malicious code update that includes emulator detection. If this app detects that it is running in an emulator, then it uses a fake C&C address instead of revealing the real one, as shown in Figure 3. This should most likely prevent automated malware sandboxes, while performing dynamic analysis, from identifying the actual C&C server.

Figure 3. Emulator detection
Figure 3. Emulator detection

Alpha Chat also uses an additional C&C address to exfiltrate non-image files with a size over 2 MB. Other files are  exfiltrated via a web socket to the C&C server.

That is a connection between the Dink Messenger and Alpha Chat apps: both were distributed on the same dedicated website. However, Dink Messenger was also carefully distributed through the Google Play store: Version 1.0 of Dink Messenger appeared on Google Play on February 8th, 2022, but with no malicious functionality included. This might have been a test by the threat actor to see whether the app would be validated and successfully uploaded to the store. On May 24th, 2022, version 1.2 was uploaded, still without malicious functionality. At that time the app was installed over 15 times. On June 10th, 2022, version 1.3 was uploaded to Google Play. This version contained malicious code, as shown in Figure 4.

Figure 4. Class name comparison of Dink Messenger without malicious functionality (left) and with (right)
Figure 4. Class name comparison of Dink Messenger without malicious functionality (left) and with (right)

Subsequently, three more versions were uploaded to Google Play with the same malicious code; the last, version 1.6, was uploaded on December 15th, 2022. All in all, these six versions have over 40 installs. We have no information on when the app was removed from the store. All the app versions with and without malicious code were signed by the same developer certificate, which means they were built and pushed to Google Play by the same malicious developer.

It is also important to mention that the Dink Messenger app available on letchitchat[.]info used the same C&C server as the Dink Messenger app on Google Play, and could perform extended malicious actions; however, the user interface of each was different (see Figure 5). Dink Messenger on Google Play implemented emulator checks (just as Alpha Chat), whereas the one on the dedicated website did not.

Figure 5. User interface of Dink Messenger downloaded from a dedicated website (left) and Google Play (right)

On August 15th, 2022, the Telco DB app (with the package name com.infinitetechnology.telcodb), which claims to provide information about the owners of phone numbers, was uploaded to an alternative app store; see Figure 6. This app has the same malicious code, a newly added emulator check with fake C&C address redirection, and an additional C&C server for file exfiltration. The C&C address is not hardcoded, as in previous cases; rather, it is returned from a Firebase server. We believe that this is another trick to hide the real C&C server, and perhaps even to update it in the future. With a high level of confidence, we assess that this app is a part of the eXotic Visit campaign.

Figure 6. User interface of the Telco DB app
Figure 6. User interface of the Telco DB app

Four days later, on August 19th, 2022, the Sim Info app was uploaded to Google Play as part of the campaign. It also claims to provide the user with information about who owns a phone number.

The malicious code communicates with the same C&C server as previous samples and is otherwise the same except that the threat actors included a native library. We elaborate on this native library in the Toolset section. Sim Info reached over 30 installs on Google Play; we have no information about when it was removed from the store.

On June 21st, 2023, the malicious Defcom app was uploaded to Google Play; see Figure 7.

Figure 7. Defcom messaging app on Google Play
Figure 7. Defcom messaging app on Google Play

Defcom is a trojanized messaging app that is part of the eXotic Visit campaign, using the same malicious code and native library to retrieve its C&C server. It uses a new C&C server, but with the same admin panel login interface shown in Figure 2. This C&C domain (zee.xylonn[.]com) was registered on June 2nd, 2023.

Before the app was removed, sometime in June 2023, it reached around six installs on Google Play.

In Figure 8, we illustrate a timeline of when all the apps were first available for download as part of the campaign.

Figure 8. Timeline first apperance XploitSPY
Figure 8. Timeline of the first appearance of XploitSPY-riddled apps that are part of the malicious campaign

Besides the already mentioned malicious apps that are part of the campaign, we were able to identify additional apps were uploaded to Google Play, and others where an attempt was made to upload, but we’re unable to tell whether the uploads were successful. Although we identified them based on the same detection names, we were not able to obtain the samples to analyze them and verify whether they are part of the same campaign. In any case, they contain malicious code that is based on XploitSPY. Table 1 list XploitSPY apps that were available on Google Play. Each of these apps had a low number of installs. A substantial number of the apps that were available on Google Play had zero installs, with some yielding under 10 installs. The highest install count from the Play Store came in at under 45.

ESET is a member of the App Defense Alliance and an active partner in the malware mitigation program, which aims to quickly find Potentially Harmful Applications (PHAs) and stop them before they ever make it onto Google Play.

As a Google App Defense Alliance partner, ESET identified all mentioned apps as malicious and shared its findings with Google, who subsequently unpublished them. All the apps identified in the report that were on Google Play are no longer available on the Play store.

Victimology

Our research indicates that malicious apps developed by eXotic Visit were distributed through Google Play and dedicated websites, and four of those apps mostly targeted users in Pakistan and India. We detected one of those four apps, Sim Info, on an Android device in Ukraine, but we don’t think Ukraine is being targeted specifically, as the app was available on Google Play for anyone to download. Based on our data, each of the malicious apps available on Google Play was downloaded tens of times; however, we don’t have any visibility into the download details.

We identified potential targets for four of these apps: Sim Info, Telco DB (com.infinitetechnology.telcodb), Shah jee Foods, and Specialist Hospital.

The Sim Info and Telco DB apps provide users the functionality to search for SIM owner information for any Pakistani mobile number, using the online service dbcenteruk.com; see Figure 9.

Figure 9. Sim Info’s interface to search for Pakistani phone number information
Figure 9. Sim Info’s interface to search for Pakistani phone number information

On July 8th, 2022, an app named Shah jee Foods was uploaded to VirusTotal from Pakistan. This app is part of the campaign. After startup, it displays a food ordering website for the Pakistan region, foodpanda.pk.

The Specialist Hospital app, available on GitHub, poses as the app for Specialist Hospital in India (specialisthospital.in); see Figure 10. After starting, the app requests the permissions necessary to perform its malicious activities and then requests user to install the legitimate app from Google Play.

Figure 10. The malicious Specialist Hospital app (left) impersonates the legitimate service (right)
Figure 10. The malicious Specialist Hospital app (left) impersonates the legitimate service (right)

We were able to find over 380 compromised accounts created in some of these apps; however, we were not able to retrieve their geolocation. Since the same insecure code was found in ten apps, we can say with a high level of confidence that they were developed by the same threat actor.

Attribution

We track this operation, active since the end of 2021, as eXotic Visit, but based on ESET research and that of others, we cannot attribute this campaign to any known group. As a result, we have internally labeled the group behind this operation as Virtual Invaders.

XploitSPY is widely available and customized versions have been used by multiple threat actors such as the Transparent Tribe APT group, as documented by Meta. However, the modifications found in the apps we describe as part of the eXotic Visit campaign are distinctive and differ from those in previously documented variants of the XploitSPY malware.

Technical analysis

Initial access

Initial access to the device is gained by tricking a potential victim into installing a fake, but functional, app. As described in the Timeline of eXotic Visit apps section, the malicious ChitChat and WeTalk apps were distributed via dedicated websites (chitchat.ngrok[.]io and wetalk.ngrok[.]io, respectively), and hosted on GitHub (https://github[.]com/Sojal87/).

At that time, three more apps – LearnSindhi.apk, SafeChat.apk, and wechat.apk – were available from the same GitHub account; we are not aware of their distribution vector. As of July 2023, these apps were not available for download from their GitHub repositories anymore. However, the same GitHub account now hosts several new malicious apps available for download. All of these new apps are also part of the malicious eXotic Visit espionage campaign, due to also containing variants of the same XploitSPY code.

The Dink Messenger and Alpha Chat apps were hosted on a dedicated website (letchitchat[.]info), from which victims were enticed into downloading and installing the app.

The Dink Messenger, Sim Info, and Defcom apps had been available on Google Play until their removal by Google.

Toolset

All analyzed apps contain customizations of the code from the malicious XploitSPY app available on GitHub. Since the first version found in 2021 until the latest version, first distributed in July 2023, we have seen continuing development efforts. Virtual Invaders has included:

  • usage of a fake C&C server if an emulator is detected,
  • code obfuscation,
  • an attempt to hide the C&C addresses from static analysis by retrieving it from its Firebase server, and
  • use of a native library that keeps the C&C server and other information encoded and hidden from static analysis tools.

What follows is our analysis of custom XploitSPY malware that, in the Defcom app, was available on Google Play.

Defcom integrates XploitSPY code with a unique chat functionality; we believe with high level of confidence the chat functionality was created by Virtual Invaders. This applies to all of the other messaging apps that have XploitSPY included.

After its initial start, the app prompts users to create an account and simultaneously attempts to obtain device location details by querying api.ipgeolocation.io and forwarding the result to a Firebase server. This server also functions as the messaging component’s server. The app interface is shown in Figure 11.

Figure 11. Defcom’s login interface (left) and in-app tabs (right)
Figure 11. Defcom’s login interface (left) and in-app tabs (right)

Defcom utilizes a native library, often used in Android app development for performance enhancement and system feature access. Written in C or C++, these libraries can be used to conceal malicious functionalities. Defcom’s native library is named defcome-lib.so.

defcome-lib.so’s purpose is to hide sensitive information such as C&C servers from static app analysis. Methods implemented in the library return a base64-encoded string that is then decoded by the malicious code during runtime. This technique isn’t very sophisticated, but it prevents static analysis tools from extracting C&C servers. Figure 12 shows the native method declarations in the Java code, and Figure 13 the implementation of the getServerUrl method in assembly code. Note that the comment above each declaration in Figure 12 is the decoded return value when calling that method.

Figure 12. Native method declarations
Figure 12. Native method declarations
Figure 13. Implementation of the native method getServerUrl in assembly language
Figure 13. Implementation of the native method getServerUrl in assembly language

The commands to execute on the compromised device are returned from the C&C server. Each command is represented by a string value. The list of the commands is:

  • 0xCO – Get contact list.
  • 0xDA – Exfiltrate file from device. The path to the file is received from the C&C server.
  • 0xFI – List files in the directory specified by the server. With an additional argument it can upload files from a specified directory to the C&C server.
  • 0xIP – Get device geolocation using the ipgeolocation.io service.
  • 0xLO – Get device GPS location.
  • 0xOF – List files in seven specific directories. In four cases the file paths are hardcoded, in three cases only folder names. An additional argument specifies the directory:
    • 0xCA – Camera
    • 0xDW – Downloads
    • 0xSS – /storage/emulated/0/Pictures/Screenshots
    • 0xTE – Telegram
    • 0xWB – /storage/emulated/0/Android/media/com.whatsapp.w4b/WhatsApp Business/Media
    • 0xWG – /storage/emulated/0/Android/media/com.gbwhatsapp/GBWhatsApp/Media
    • 0xWP – /storage/emulated/0/Android/media/com.whatsapp/WhatsApp/Media

Interestingly, GB WhatsApp is an unofficial cloned version of WhatsApp. While it offers additional features that have made it quite popular, it is important to note that it’s not available on Google Play. Instead, it is often found on various download websites, where versions of it are frequently riddled with malware. The app has a substantial user base in several countries, including India, despite its associated security risks.

Figure 14 and Figure 15 show the exfiltration of a contact list and a directory listing.

Figure 15. File list exfiltration
Figure 15. File list exfiltration

Network infrastructure

Virtual Invaders use ngrok as its C&C server; the service is a cross-platform application that enables developers to expose a local development server to the internet. ngrok can create a tunnel that connects using ngrok servers to a local machine. ngrok allows its users – so, the attackers in this case – to reserve a particular IP address or redirect the victim to the attacker’s own domain on a specific port.

Conclusion

We have described the eXotic Visit campaign, operated by the Virtual Invaders threat actor, which has been active since at least the end of 2021. Throughout the years the campaign has evolved. Distribution started on dedicated websites and then even moved to the official Google Play store.

We have identified the malicious code used as a customized version of the open-source Android RAT, XploitSPY. It is bundled with legitimate app functionality, most of the time being a fake, but functioning, messaging application. The campaign has evolved over the years to include obfuscation, emulator detection, and hiding of C&C addresses. The purpose of the campaign is espionage and probably is targeting victims in Pakistan and India.
