Summary

Dampig.A is a malicious SIS file dropper, that pretends to be a crack for version 3.2 of FSCaller application. The Dampig.A disables some system applications and third party file managers and installs several variants of Cabir worm on the phone.

The Dampig.A trojan disables Bluetooth UI, system file manager, Messaging application and phone book on the infected handheld. Also the Dampig.A will corrupt the uninstallation information in the system installer, so that it cannot be uninstalled without being disinfected first.

The menu application is not disabled, so the user is able to use his phone, and download Anti-Virus to disinfect the phone without any special tool.

None of the Cabir variants installed on the phone will start automatically, but some of the applications that are replaced with Cabir executables, such as Messaging application, will be most likely called and thus executed by the user.

All of the Cabir variants worm dropped by Dampig.A are already detected. So the Dampig.A is already detected and stopped without need for updated Anti-Virus database.

Please note, that even as the FSCaller application that Dampig.A prenteds to crack, has similar name to our product naming. It has nothing to do with F-Secure. FSCaller is software made by SymbianWare OHG in Germany.

Removal

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 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.
