Skulls.B is a Trojan that only affects cellular phones that use the operating system Symbian. Initially, it aims Nokia 7610 cellphones, but other devices based in the same software could also be affected.
Skulls.B changes all the icons into another icon belonging to a certain system application. At the same time, it blocks the cellphone menu, so that no other functionalities than calling and answering calls will be available.
Additionally, it installs files belonging to other malware affecting Symbian-based cellphones, detected as SymbOS/Cabir.A.worm.
Both Skulls.B and Cabir.A need the user intervention in order to be run on the cellphone. Before the malicious files are installed, the user receives a security warning.
Skulls.B has been distributed via forums specialized in cellular telephony.
Skulls.B is easy to recognize once it has affected the cellphone, as it changes all the application icons into a different one.
