Please follow the instructions for removing worms.
W32/Sluter-A exploits weak network security. If W32/Sluter-A has spread over your network you should check permissions and passwords, particularly domain administrator passwords, on your network.
Windows NT/2000/XP
In Windows NT/2000/XP you will also need to edit the following registry entry. The removal of this entry is optional in Windows 95/98/Me. Please read the warning about editing the registry.
At the taskbar, click Start|Run. Type 'Regedit' 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 entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Superslut = msslut32.exe
and delete it if it exists.
Close the registry editor.
More Information
W32/Sluter-A is a network aware worm.
W32/Sluter-A scans port 445 of a large number of randomly generated IP addresses. When an open port is found the worm will test the shares C$ and Admin$ for the following administrator passwords:
admin
root
1
111
123
1234
123456
654321
!@#$
asdf
asdfgh
!@#$%
!@#$%^
!@#$%^&
!@#$%^&*
server
If the worm gains access to one of the shares then the worm executable will be copied to the system folder of that share with the filename msslut32.exe. W32/Sluter-A will then schedule a job to start the worm on the compromised computer.
W32/Sluter-A creates the following registry entry so that the worm is run when Windows starts up:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Superslut = msslut32.exe
