DescriptionThis backdoor program is primarily designed to allow remote malicious users to connect to target systems, leaving the target adversely compromised.

It has two components, the server and the client component. The server component is installed on the target system while the client component is with the remote user. The server listens to and opens a port where the client can connect to. Once a connection is established, the remote user may then do the following to the compromised system:

Get password
Display message box
View target's hard disk
Reboot system
Capture target's working screen
Lockup function that utilizes the KERNEL32.DLL to lock up the host PC
Get target's Window version (Win95/98)
Restart the backdoor
Open/close CD-ROM
Kill antivirus
Preview
Send module


The user may also make use of the backdoor's destructive capabilities as follows:

Kill Windows - It kills Windows by zapping vital Windows files that obliges the affected user to reinstall Windows
Kill DOS – It deletes COMMAND.COM.
