Brief Description 

    

Multidrp.A is a Trojan that that only affects cellular phones that use the operating system Symbian 60 series.

Multidrp.A disables certain applications by overwriting their main executable files with a copy of itself. Some of these applications belong to third parties, but others belong to the own operating system. For example, AppMngr is the Application Manager, and once it is overwritten, the affected user will not be able to uninstall applications.

The Trojan also installs a copy of the SymbOS worm Cabir.A on the cellphone, and copies several files to the SD memory of the cellphone, aiming at affecting computers with two different worms, detected as Korgo.BF and Wukill.A, when the SD memory is connected to a computer.

 

Multidrp.A reaches the cellphone in a malicious SIS file, which is the type of files used to distribute Symbian applications.

Keep in mind that Multidrp.A needs the user intervention in order to be run on the cellphone. Before the malicious file is installed, the user receives a security warning.

Visible Symptoms 

    

Multidrp.A is easy to recognize once it has affected the cellphone, as it disables certain applications, such as the Application Manager.
