The worm uses the following icon, to make it appear that the file is a folder.

Like its predecessors, this worm checks the system date. If it is the 25th March 2005 or later, the worm simply exits and does not propagate.

The virus copies itself into the Windows System directory as i1ru54n4.exe, for example:

C:\WINNT\SYSTEM32\i1ru54n4.exe

It also creates other files in this directory to perform its functions:

  • go54o.exe (24,064 bytes) - DLL to perform mailing
  • ii5nj4.exe (1,536 bytes) - DLL loader
  • i1ru54n4.exeopen (~16KB) - file to be sent via email

The following Registry key is added to hook system startup:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\
    CurrentVersion\Run "rate.exe" = C:\WINNT\SYSTEM32\i1ru74n4.exe

Additionally, the following Registry key is added:

  • HKEY_CURRENT_USER\Software\winword "frun"

A mutex called "imain_mutex" is created to ensure only one instance of the worm is running at a time.

This worm attempts to terminate the process of security programs with the the following filenames:

  • ATUPDATER.EXE
  • ATUPDATER.EXE
  • AUPDATE.EXE
  • AUTODOWN.EXE
  • AUTOTRACE.EXE
  • AUTOUPDATE.EXE
  • AVLTMAIN.EXE
  • AVPUPD.EXE
  • AVWUPD32.EXE
  • AVXQUAR.EXE
  • CFIAUDIT.EXE
  • DRWEBUPW.EXE
  • ICSSUPPNT.EXE
  • ICSUPP95.EXE
  • LUALL.EXE
  • MCUPDATE.EXE
  • NUPGRADE.EXE
  • NUPGRADE.EXE
  • OUTPOST.EXE
  • UPDATE.EXE

Symptoms

  • Port 2745 (TCP) open on the victim machine
  • Outgoing messages matching the described characteristics
  • Files/Registry keys as described

Method of Infection

Mail Propagation

This virus constructs messages using its own SMTP engine. Target email addresses are harvested from files with the following extensions on the victim machine:

  • .adb
  • .asp
  • .cfg
  • .dbx
  • .eml
  • .htm
  • .mdx
  • .mmf
  • .nch
  • .ods
  • .php
  • .pl
  • .sht
  • .tbb
  • .txt
  • .wab
  • .xml

The virus spoofs the sender address by using a harvested address in the From: field.

The virus avoids sending itself to addresses containing the following:

  • @avp.
  • @hotmail.com
  • @microsoft
  • @msn.com
  • local
  • noreply
  • postmaster@
  • root@

Remote Access Component

The virus listens on TCP port 2745 for remote connections. It attempts to notify the author that the infected system is ready to accept commands, by contacting various websites, calling a PHP script on the remote sites. At the time of this writing this script is inaccessible. The websites are contacted every 27.8 hours.

http://postertog.de/scr.php
http://www.gfotxt.net/scr.php
http://www.maiklibis.de/scr.php

The format of the HTTP packets sent to the above websites is :-

GET /scr.php?p=2745 HTTP/1.1
User_Agent: beagle2_proclivity
Host: postertog.de

Note: The value of the Host field will change depending on which website is being contacted

Peer To Peer Propagation

Files are created in folders that contain the phrase shar :

  • ACDSee 9.exe
  • Adobe Photoshop 9 full.exe
  • Ahead Nero 7.exe
  • Matrix 3 Revolution English Subtitles.exe
  • Microsoft Office 2003 Crack, Working!.exe
  • Microsoft Office XP working Crack, Keygen.exe
  • Microsoft Windows XP, WinXP Crack, working Keygen.exe
  • Opera 8 New!.exe
  • Porno pics arhive, xxx.exe
  • Porno Screensaver.scr
  • Porno, sex, oral, anal cool, awesome!!.exe
  • Serials.txt.exe
  • WinAmp 5 Pro Keygen Crack Update.exe
  • WinAmp 6 New!.exe
  • Windown Longhorn Beta Leak.exe
  • Windows Sourcecode update.doc.exe
  • XXX hardcore images.exe

All Information

Overview -

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
