How to know if Zeus Trojan is in your computer

Computers infected with this version of ZeuS will have the following files and folders installed. The location depends on whether the victim has Administrator rights. The files will most likely have the ‘hidden’ attribute set to hide them from casual inspection.

With Administrator rights:

%systemroot%\system32\sdra64.exe (malware) 
%systemroot%\system32\lowsec
%systemroot%\system32\lowsec\user.ds (encrypted stolen data file) 
%systemroot%\system32\lowsec\user.ds.lll (temporary file for stolen data) 
%systemroot%\system32\lowsec\local.ds (encrypted configuration file)

Without Administrator rights:

%appdata%\sdra64.exe
%appdata%\lowsec
%appdata%\lowsec\user.ds
%appdata%\lowsec\user.ds.lll
%appdata%\lowsec\local.ds

ZeuS also makes registry changes to ensure that it starts up with Administrator privileges:

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
From: "Userinit" = "C:\WINDOWS\system32\userinit.exe"
To:   "Userinit" = "C:\WINDOWS\system32\userinit.exe,C:\WINDOWS\system32\sdra64.exe"

Without Administrator rights:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Add:  "Userinit" = "C:\Documents and Settings\<user>\Application Data\sdra64.exe"

The sdra64.exe program uses process injection to hide its presence in the list of running processes. Upon startup, it will inject code into winlogon.exe (if Administrator rights available) or explorer.exe (for non-Administrators) and exit. The injected code infects other processes to perform its data theft capabilities.
