Threat description



Dampig.B is a malicious SIS file dropper, that pretends to be a pirate copied versopn of FaceWave application. The Dampig.B disables some system applications and third party file managers and installs several variants of Cabir worm on the phone.

The Dampig.B trojan disables Bluetooth UI, system file manager, Messaging application and phone book on the infected handheld.

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.
