Summary
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.
Removal
You can set the F-Secure app to scan your device for viruses and other threats automatically. Once the app has completed its scan of the files on your device, you may assess any detected file or files and opt to remove it.
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 'com.lbe.security' (LBE Security Master Application). This appears to be a security utility program intended for Chinese language users.
