SubSeven was made to fill in the gaps left by NetBus.
NetBus was the first 'point and click' trojan that made it very easy for hackers to abuse an infected system.
The makers of SubSeven wanted to take this even further and give the hackers even more control than NetBus ever could.

SubSeven can do everything that NetBus can do. This includes things such as

File controls
Upload / Download
Move, Copy, Rename, Delete
Erase harddrives and other disks
Execute programs
Monitoring
Can see your screen as you see it
Log any/all keypresses (even hidden passwords)
Open/close/move windows
Move mouse
Network control
Can see all open connections to and from your computer
Can close connections
Can 'bounce' or relay from their system to yours, so wherever they connect it seems as if You are doing it. This is how they
prevent getting caught breaking into other computer systems and get You in trouble!


The SubSeven trojan can also be configured to inform someone when its infected computer connects to the internet, and tells that
person all the information about you they need to use the trojan aginst you.

This notification can be done over an IRC network, by ICQ, or by email.
