The “Gozi” Trojan is a well known piece of crimeware that has been around for a couple of years now. It is surprising to see that this one continues to be actively hosted and distributed.

This file in turn, installs itself as “xrt_mwbn.exe” and runs various components that gather data off of the victim’s machine and sends it off to an nginx web server.
