W32/Rbot-GQ

Please follow the instructions for removing worms.

You will also need to edit the following registry entries, if present. Please read the warning about editing the registry.

Renaming the registry editor

• Using Windows explorer, browse to the Windows folder (usually C:\Windows or C:\Winnt) right-click Regedit.exe and make a copy of it.
• Rename the copy of Regedit.exe to Regedit.com.
• At the taskbar, click Start|Run. Type 'Regedit.com' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.

Locate the HKEY_LOCAL_MACHINE entries:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Windows Media Player
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\
Windows Media Player
HKLM\System\CurrentControlSet\Control\Lsa\Windows Media Player
HKLM\Software\Microsoft\OLE\Windows Media Player

and delete them if they exist.

Each user has a registry area named HKEY_USERS\[code number indicating user]\. For each user locate the entries:

HKCU\[code number]\Software\Microsoft\Windows\CurrentVersion\Run\
Windows Media Player
HKCU\[code number]\Software\Microsoft\Windows\CurrentVersion\RunServices\
Windows Media Player
HKCU\[code number]\System\CurrentControlSet\Control\Lsa\Windows Media Player
HKCU\[code number]\Software\Microsoft\OLE\Windows Media Player

and delete them if they exist.

Close the registry editor.

• Download and install the Microsoft patches mentioned. On standalone computers, update with all relevant security patches from Windows update.
• Check your administrator passwords and review network security.
• To renable DCOM you can edit the registry, but it's better to use Dcomcnfg.exe. See Microsoft article 825750 for details.
• The HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = "1" setting does not allow enumeration of SAM accounts and names. The default is "0". It can be changed in Local Security Policy. See Microsoft article 246261 for details.
• Replace the Hosts file from a backup or edit it in Notepad to remove the changes that the worm has made.

W32/Rbot-GQ is a network worm with IRC backdoor functionality.

In order to run automatically when Windows starts up the worm copies itself to the Windows system folder with a random filename and creates the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Windows Media Player
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\Windows Media Player
HKLM\System\CurrentControlSet\Control\Lsa\Windows Media Player
HKLM\Software\Microsoft\OLE\Windows Media Player
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Windows Media Player
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices\Windows Media Player
HKCU\System\CurrentControlSet\Control\Lsa\Windows Media Player
HKCU\Software\Microsoft\OLE\Windows Media Player

Once installed, W32/Rbot-GQ connects to a preconfigured IRC server and channel to await further commands. These commands allow an attacker to perform any of the following actions

send/receive files by DCC
start a tftp, http, rlogin or socks4 proxy server
download/upload files by HTTP or FTP
scan other machines in order to infect them
secure the infected system against similar attacks
network packet sniffing
list and/or kill currently running processes, threads and/or services
log keyboard events
captures images of the screen or from any attached webcam
search for product keys, passwords
list/flush the ARP and DNS caches
start a remote shell
execute arbitrary shell commands
flood another machine with ICMP,SYN,PING,raw IP,UDP or TCP packets
reboot the machine
TCP redirection
send email via SMTP

The worm spreads by scanning many IP addresses (generated either randomly or sequentially) for machines which may be infected via any of the following methods:

Vulnerabilities:
LSASS (MS04-011)
RPC-DCOM (MS03-039)
RPC-DCOM2 (MS04-012)
WebDav (MS03-007)
Universal Plug-and-Play (MS01-059)
Dameware (CAN-2003-1030)

Backdoors:
W32/Mydoom
W32/Bagle
Troj/Optix
W32/Sasser
Troj/Netdevil
Troj/Kuang

Network services with weak passwords:
netbios

After infection, W32/Rbot-GQ disables network services with known vulnerabilities by changing the following registry entries:

HKLM\SOFTWARE\Microsoft\Ole\EnableDCOM = "N"
HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = 1

If instructed to search for product keys, the worm attempts to retrieve keys for the following software:
