Trojan:Android/Voxv.B is a trojanized version of a popular game app that harvests and silently forwards sensitive details from the infected device to remote contacts.


Once the scan is complete, the F-Secure security product will ask if you want to uninstall the file, move it to the quarantine or keep it installed on your device.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

Trojan:Android/Voxv.B is a trojanized version of the legitimate and popular game app 2048 Puzzle. The trojan uses the same name and look as the original app, but requests more permissions than the legitimate game, including permission for writing, reading and sending SMS messages. Due to the similarity between the legimitate and trojanized apps, users would need to be alert to the additional permissions requested by the trojan to be able to differentiate between them.

Once installed, the trojan collects the following details from the device:

  • International Mobile Subscriber Identity (IMSI) number
  • International Mobile Equipment Identity (IMEI) number
  • Device type, brand, model and release version
  • Device ID, SIM serial number and phone number (line1)
  • API level and display type
  • List of installed apps

These details are silently forwarded to specified remote servers; some of the details are also sent via SMS to a specified phone number.

In addition to data harvesting, the trojan also checks the device for the presence of a specific app with the package name '' (LBE Security Master Application). This appears to be a security utility program intended for Chinese language users.
