Advanced
W32/Forbot-CI is an IRC backdoor Trojan and network worm for the Windows 
platform.

In order to run automatically when Windows starts up the worm moves 
itself to the Windows system folder as svshost.exe and creates the 
following registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Microsoft Windows Update = svshost.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Microsoft Windows Update = svshost.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Microsoft Windows Update = svshost.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Microsoft Windows Update = svshost.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Microsoft Windows Update = svshost.exe

W32/Forbot-CI also creates its own service named "Microsoft Update", 
with the display name "Microsoft Windows Update".

Once installed, W32/Forbot-CI connects to a preconfigured IRC server and 
joins a channel from which an attacker can issue further commands. These 
commands can cause the infected machine to perform any of the following 
actions:

flood a remote host (by either ping or HTTP)
start a SOCKS4 proxy server
start an HTTP server
start an FTP server
portscan randomly-chosen IP addresses
execute arbitrary commands
steal information such as passwords and product keys
upload/download files

The worm can spread to unpatched machines affected by the LSASS 
vulnerability (see MS04-011) and through backdoors left open by the 
Troj/Optix Trojans.

Description
W32/Rbot-PC is a member of the W32/Rbot family of worms with a backdoor 
component that spread on weakly protected network shares on the Windows 
platform.

The worm spreads as a result of receiving the appropriate command by 
scanning random IP addresses for open SMB ports (445) and trying to copy 
itself to the Windows system folder on the remote Admin$ and C$ shares.

W32/Rbot-PC uses an internal dictionary of common passwords to gain 
access. The worm attempts to schedule the copied file for later 
execution on the remote machine.

In addition the worm also has the ability to scan for and exploit common 
vulnerabilities on the Windows platform such as the LSASS vulnerability 
(MS04-012) as well as ports opened by other worms such as W32/Bagle or 
W32/MyDoom.

W32/Rbot-PC also has a backdoor component that allows a malicious user 
remote access to an infected computer.

When run the worm attempts to contact a remote IRC server and join a 
specific channel to listen for commands.

and users, kill processes, download and execute files, send email, 
remotely control a connected web cam, sniff network traffic, log 
keystrokes, steal keys for certain games or launch various 
denial-of-service attacks against an attacker-specified target.
