Skulls.Q is a combination of several previous Skulls variants.
Skulls.Q contains component files from Skulls.D and Skulls.N among
other variants. Skulls.Q also drops SymbOS/Commwarrior.B and several Cabir variants on the
phone and component files from SymbOS/Doomboot.A trojan. The Doomboot files are dropped into folder where they cannot affect the system,
so even as the phone is infected with Skulls.Q it can still boot normally. Skulls.Q also contains bluetooth distribution component from SymbOS/Onehop.A,
but the component is installed so that it does not start automatically and user
cannot execute it.
