This Trojan was specially engineered to steal sensitive electronic banking data by installing itself in the WindowsSystem32 directory, where it creates the rootkit-hidden wsnpoem folder that it populates with the encrypted ntos.exe, audio.dll and video.dll files (in effect, the two so-called “DLLs” are used for configuration and storage purposes).
It also creates a registry entry that enables automatic launch each time Windows starts up. To harvest the sensitive electronic banking details, it injects code into winlogon.exe and iexplorer.exe processes and downloads one or several files from a remote server. It employs these files to store the data it gathers by monitoring the Web browser activity.
Head of Bitdefender Antimalware Research, Sorin Dudea said, “ZBot and its family have an increased damage potential, as they are able to deactivate the firewall, steal sensitive financial data (such as credit card and account numbers, as well as login details), make screen shots and create logs of current working sessions. In addition, it is capable of downloading supplemental components and providing a remote hacker with the means to access the compromised system. Hence, we strongly recommend you not to open these e-mails and their attachments, and to install and activate a reliable anti-malware, firewall and spam filter solution.”
