backdoor Trojans.
Vulnerabilities:
Universal PNP (MS01-059)
WebDav (MS03-007)
RPC DCOM (MS03-026, MS04-012)
WorKStation service (MS03-049)
LSASS (MS04-011)

Services:
NetBios
MS SQL
Backdoors:
W32/Bagle
W32/MyDoom
Troj/Optix
W32/Sasser
W32/Agobot-RB deletes files and folders containing the text "sound".
W32/Agobot-RB copies itself to the Windows system folder and creates the
following registry entries to run itself automatically on computer
login:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Systems Backups =
windrives.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Systems Backups =
windrives.exe
On NT-based versions of Windows (NT,2000,XP) windrives.exe is registered
as a service process with a servicename "Restoreds" and a displayname
"Systems Backups". The service has a start-type of automatic. Registry
entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\Restoreds
The worm blocks access to security-related websites by adding the
following entries to the Windows hosts file:

Description
W32/Sdbot-WG is a network worm and IRC backdoor Trojan for the Windows
platform which allows a remote intruder to access and control the
computer via IRC channels. W32/Sdbot-WG also drops a file to the current
folder that is detected by Sophos products as Troj/NtRootK-F.
The backdoor component joins a specific channel on an IRC server and
then runs continuously in the background as a service process, listening
on the IRC channel for specific commands and carrying out the
appropriate actions.

Advanced
W32/Mytob-K is a mass-mailing worm and backdoor Trojan that targets
users of Internet Relay Chat programs.
W32/Mytob-K is also capable of spreading through various operating
system vulnerabilities such as LSASS (MS04-011).
When first run W32/Mytob-K copies itself to the Windows system folder as
sys32.exe and creates the following registry entries:
HKCU\Software\Microsoft\OLE
WINTASK
sys32.exe
HKCU\System\CurrentControlSet\Control\Lsa
WINTASK
sys32.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
WINTASK
sys32.exe
HKLM\Software\Microsoft\Ole
WINTASK
sys32.exe
HKLM\System\CurrentControlSet\Control\Lsa
WINTASK
sys32.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
WINTASK
sys32.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
WINTASK
sys32.exe
W32/Mytob-K copies itself to the root folder as:
funny_pic.scr
my_photo2005.scr
see_this!!.scr
and creates the helper file hellmsn.exe (detected by Sophos as
W32/Mytob-D) in the same location.
W32/Mytob-K also appends the following to the HOSTS file to deny access
to security-related websites:
