Skulls + Cabir mobile trojan
p2pnet.net News:- A variant of the SymbOS/Skulls.A Trojan is now waiting to infect mobiles.
Skulls.B has similar functionality to Skulls.A but uses different files and drops the SymbOS/Cabir.B, says F-Secure, which also identified the first version.
“Skulls.B is a malicious SIS file trojan that will replace the system applications with non-functional versions,” it states.
The Cabir dropped by Skulls.B activates if a user goes to the cabir icon in the phone menu and runs Cabir from there. It will then launch and try to infect other phones.
Unlike Skulls.A, the Skulls.B variant doesn’t show pop-up messages during install (except the “Installation security warning – unable to verify supplier” message shown by the operating system), says F-Secure.
