OK, so at my school over the last couple weeks i have been testing and writing scripts to remotely dump passwords, start a bind shell, etc. Anyway i did it for the lol's , i didnt even looked at any 'confidential' files and i have been using it mostly to troll people during class (max volume, text to speech, gg). But anyway i did it to my "friend" during class and he told the teacher what ive been doing so he didnt get in trouble, now the IT guys want to 'investigate' my computer. So ive gotten rid of all my files (including the passwords of the head of campus and head of IT, XD), cleared all my event logs and powershell history, and cleaned the registry up a bit. Anything else i should do?
