I know that our school network is actually quite secure, and tbh the only way you can do any damage is to get an admins / teachers password. I got that once by writing a batch file and shoving it on my memory stick so when I plugged it into a machine it would copy and run this keylogger. Well anyway, I got a teachers password and I gave it to a mate, who managed to change everyone's password in my year, he got bollocked for it though lol.
The only other thing I've done it write a .bat file which brings up dos and writes a message saying "You are trying run un-authorised programs, if you are not type n" so the person types 'n' and it shuts down their pc lol.
- Never take anything for face value, never trust the system and never put up with an answer that you don't agree with. It's about time people realised the truth of this world.
CLICK IT NAO!!!
