Summary of the Attack Process
A user whose PC is infected and who tries to access a bank Web site triggers the Zeus malware, which “asks the user to download an authentication or security component onto their mobile device in order to complete the login process.” That security component, disguised as Trusteer’s Rapport product, but actually the Zeus mobile variant, gives fraudsters control of both the user’s PC and the user’s phone. At that point, the Zeus malware can generates a fraudulent transaction on behalf of the user and authenticate it by intercepting the SMS verification message on the phone and forwarding it to the malware on the PC. The mobile Zeus variant then deletes the confirmation message from the user’s mobile device so the user will not see it and enters the code on the PC to complete the transaction.
