Windows platform with backdoor functionality.

W32/Rbot-SQ targets weakly protected network shares and machines 
unpatched against known vulnerabilities.

The backdoor component connects to a predefined IRC server and waits 
for commands from a remote attacker.

When first executed, W32/Rbot-SQ copies itself to the Windows system 
folder with the filename mcafeee.exe and in order to be able to run 
automatically when Windows starts up creates the registry entries:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Windows Media Player = "mcafeee.exe"

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Windows Media Player = "mcafeee.exe"

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\

dword:00000001
HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = 
dword:00000001

W32/Rbot-SQ spreads using a variety of techniques including 
exploiting weak passwords on computers and SQL servers, exploiting 
operating system vulnerabilites (including DCOM-RPC and LSASS) and 
using backdoors opened by other worms or Trojans.

W32/Rbot-SQ can be controlled by a remote attacker over IRC channels. 
The backdoor component of W32/Rbot-SQ can be used to:

start a proxy server
enable remote login (rlogin)
log keystrokes on the infected computer
filesystem manipulation
start/stop system services
take part in denial of service attacks (DoS)

Description
W32/Traxg-E is a mass-mailing worm which also spreads by copying 
itself to network shares.

W32/Traxg-E sends emails with itself as an attachment to addresses 
found in the Outlook Express address book.

W32/Traxg-E may copy itself as a random filename to any of the 
following folders:

\fonts
\help
\system
\temp
\web

The worm may create the files C:\FOLDER.HTT and nethood.htm, also 
detected as W32/Traxg-E. This file exploits the "Microsoft VM ActiveX 
Component" vulnerabilty, associated with certain versions of 
Microsoft Internet Explorer, to run further executable code. This 
vulnerability allows an HTML-based script to access the file system 
or registry without any of the usual security restrictions placed on 
ActiveX controls. For further information see Microsoft security 
bulletin MS00-075.

W32/Traxg-E adds a user account "admin" if it does not already exist.
