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.
