Technical DetailsWurm Bagle.M is a polymorph worm that uses its own SMTP engine to spread. Like the prior Bagle versions, it also has a backdoor component (TCP port 2556) and tries to copy and spread itself over shared networks.
The worm creates the following files:
%System%\winupd.exe
%System%\winupd.exeopen
%System%\winupd.exeopenopen
%System%\winupd.exeopenopenopen

When activated, the worm makes the following registry entry, for ensuring automatic start:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\ Windows\CurrentVersion\Run\"winupd.exe"="%System%\winupd.exe"

If it finds the following active tasks, the worm tries to terminate them:

The worm deletes the following values:
-9XHtProtect
-Antivirus
-HtProtect
-ICQ Net
-ICQNet
-My AV
-Special Firewall Service
-Tiny AV
-Zone Labs Client Ex
-service
from the following registry entries, to deactivate their automatic start:
HKEY_LOCAL_MACHINE\Software\Microsoft\ Windows\CurrentVersion\Run HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Run

The worm opens TCP port 2556. If the virus file is sent through this port, the worm allows any attacker to download the %WinDIR% folder. This file is saved as
%WinDIR%\iuplda%x%.exe (%x% is a random character). It tries to spread over file sharing networks, like Kazaa and iMesh and to copy itself on them.

The files are saved in folders containing the string "shar" in their name. The following file names are used:
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 Screensaver.scr

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


Wurm/Bagle.M tries to infect .exe files on local drives. The infectious routine is varied and depends on the worm file. The worm searches for email addresses to send itself to, into files of type:
adb
asp
cfg
cgi
dbx
dhtm
eml
htm
jsp
mbx
mdx
mht
mmf
msg
nch
ods
oft
