ZeuS is a well-known crimeware kit. Its purpose is to defraud users who perform online banking from an infected computer.;xNLx;;xNLx;Zitmo (Zeus In The Mobile), is an element of the Zeus crimeware. Its sole purpose is to intercept SMS messages sent by banks to customers making financial transactions online (in the jargon, mTAN codes), directly from the victims' mobile phones.
This 1st version of Zitmo presented itself as a Nokia update and also carried a legitimate digital signature.
The second Zitmo attack, in February 2011, targeted a much broader set of mobile devices: Symbian, Windows Phone and BlackBerry.
The WinCE variant showed very little difference with the original Symbian .A variant.
The BlackBerry version showed very little difference with the original Symbian .A version.
The 3rd Zitmo attack released Android variants of the trojan. These versions were far more primitive than their pairs.
Created nearly a year after the 1st Symbian/Zitmo trojan, Android/Zitmo only intercepts (and deletes) incoming SMS messages and is unable to receive commands from a C&C server.
The latest Android variants are now much more elaborate.
Android/Zitmo.E now not only intercepts incoming SMS, but they now can also receive C&C commands through SMS messages.
This BlackBerry variant shows very little differences with its predecessors.
