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.

Aliases

• W32.Beagle.I@MM (NAV)

• Win32.Bagle.I (CA)

Characteristics

This variant of W32/Bagle is functionally similar to the .F variant.  It bears the following characteristics:

• The virus copies itself into the Windows System directory as I11R54N4.EXE. For example:
  
  
  • C:\WINNT\SYSTEM32\i11r54n4.exe (21,212 bytes)
    

• The following Registry key is added to hook system startup:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\
    CurrentVersion\Run
    "rate.exe" = C:\WINNT\SYSTEM32\i11r54n4.exe
    

• The following Registry key is also added:

  • HKEY_CURRENT_USER\Software\Windor

• It also creates other files in the Windows Systemdirectory to perform its functions:

  • go154o.exe (19,968 bytes) - DLL to perform mailing
  • i1i5n1j4.exe (1,536 bytes) - DLL loader
  • i11r54n4.exeopen (21,348 bytes) - ZIP file, that is sent via email
    
• 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 worm uses the following icon, to make it appear that the file is a folder:
  
• The worm opens port 2745 (TCP) on the victim machine

Mail Propagation

Messages are constructed as follows:

Symptoms

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://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

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

Manual Removal Instructions
To remove this virus "by hand", follow these steps:

1. Reboot the system into Safe Mode (hit the F8 key as soon as the Starting Windows text is displayed, choose Safe Mode.
2. Delete the files following from your WINDOWS System directory (typically C:\Windows\System or C:\Winnt\System32)
   i11r54n4.exe
   go154o.exe
   i1i5n1j4.exe
   i11r54n4.exeopen
3. Edit the registry
   • Delete the "rate.exe" value from
     • HKEY_CURRENT_USER\Software\Microsoft\
       Windows\CurrentVersion\Run
   • Delete the following key for W32/Bagle.h@MM:
     • HKEY_CURRENT_USER\Software\Winexe
   • Delete the following key for W32/Bagle.i@MM :

     • HKEY_CURRENT_USER\Software\Windor

4. Reboot the system into Default Mode
