Arrival Details

This File infector arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

Installation

This File infector drops the following copies of itself into the affected system:

{random filename}. {exe/cmd/pif}

It drops the following files:

%User Temp%\IXP000.TMP\@.cmd
%User Temp%\IXP000.TMP\@.cm_
%User Temp%\IXP000.TMP\@.cmdx
%AppDataLocal%\CSIDL_
%AppDataLocal%\CSIDL_X
%User Temp%\{Random Numbers}.bat
%User Temp%\{Random letters}.exe
{Drive}\autorun.inf
{Drive}\{Random Letters}.exe
%User Temp%\IXP000.TMP\@.cmd.config

(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000, XP, and Server 2003, or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, and 8.. %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000, XP, and Server 2003, or C:\Users\{user name}\AppData\Local on Windows Vista, 7, and 8.)

It adds the following processes:

%System%\net1 stop MpsSvc
cmd.exe /c echo on error resume next:CreateObject("WScript.Shell").Run "%User Temp%\IXP000.TMP\@.cmd",1: >"%User Startup%\{random letter}.vbs"
cmd.exe /c ""%User Temp%\{random numbers}.bat" "%User Temp%\IXP000.TMP\@.cmd" "

(Note: %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.. %User Startup% is the current user's Startup folder, which is usually C:\Windows\Profiles\{user name}\Start Menu\Programs\Startup on Windows 98 and ME, C:\WINNT\Profiles\{user name}\Start Menu\Programs\Startup on Windows NT, C:\Documents and Settings\{User name}\Start Menu\Programs\Startup on Windows XP, or C:\Users\{user name}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup on Windows Vista, 7, and 8.)

It displays the following fake error messages:

It adds the following mutexes to ensure that only one of its copies runs at any one time:
