The worm does not send any emails to addresses containing the following strings:
@avp. @foo @hotmail.com @iana @messagelab @microsoft @msn abuse admin anyone@ bsd bugs@ cafee certific contract@ f-secur feste free-av gold-certs@ google help@ icrosoft info@ kasp linux listserv local nobody@ noone@ noreply ntivi panda pgp postmaster@ rating@ root@ samples sopho spam support unix winrar winzip

Technical DetailsWhen activated, Worm/Bagle.R checks if the system date is 2006 or later. If this is the case, the worm deletes the following registry entry:
HKEY_CURRENT_USER\SOFTWARE\windirects,
and the following registry value: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run directs.exe"="%SystemDIR%\directs.exe"
so that the worm is not activated by the next system start and all its functions are deleted.

But if it is not the case, it creates the following files:
%SystemDIR%\direct.exe
%SystemDIR%\direct.exeopen
The worm makes the following registry entry, for automatic start:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"direct.exe"=" %SystemDIR%\direct.exe"
and it also enters:
HKEY_CURRENT_USER\SOFTWARE\windirects

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

Then it opens TCP port 2556. If an attacker sends an especially formatted message through the port, the worm allows a file download in %WinDIR%. This file is saved as %WinDIR%\iuplda%x%.exe.
The worm tries to spread over shared networks (like Kazaa or iMesh) and copies itself in directories containing "shar" string. The worm uses the following file names:
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

It scans drive C:\ and tries to infect .exe files. The email routine is polymorph and depends on the file infection.
