CyberJack v1.00 - 21 March 2001
-------------------------------
Current Release: Server v1.01
                 Client v1.00

This is my first backdoor I've coded.
Cyberjack is developed using Visual Basic
and therefore, it requires VB6 runtime 
files in order to work.
In addition, both the server and client
needs the Winsock ActiveX control, mswinsck.ocx.

Package contents:

RELEASE Folder:
- Exotic.exe (The CyberJack Backdoor Server)
- CyberJack.exe (The CyberJack Backdoor Client)

Changes in Server version 1.01:
- Fixed system lock bug which causes system tray to be visible on some computers.
- Added Beep feature.

System Requirements:

- Intel Pentium processor or later (Pentium II or later recommended)
- 8 MB RAM
- 200 Kb hard disk space
- Windows 95/98/98SE/ME/NT/2000
- TCP/IP stack
- Network connection (LAN or Internet)
Note: CyberJack works best in Win9x systems. However,
when running on WinNT and Win2K systems, some functions will not work.
CyberJack is tested to run ideally on LAN/intranet environment.
It is not tested to run on Internet based WAN environment.


Instructions:
Give the server to the victim.
All the victim needs to do is to run the server and it will auto-install by itself
The server will be activated the next time the computer reboots and will remain in memory.
Once the server is activated, fire up the client and enter
