Alright im trying to hack my school's website, ( i get points if i do it successfully)
i scanned the webserver ip and i found, ports 80 (http), 3389, 25 and 8081 open.

i know port 3389 is to remote access it and i have done that already, but
when i use the Remote Desktop connection thing, i get into the computer successfully, but it asks me to log into the computer, and i need to somehow brute force the password.
how can i do this?

Also what can i do with port 25 and 8081?
