Well I don't know if you can do it now..probally not, but I used to use command prompt to hack websites. I used telnet or it might have been ftp command to get access to websites.

Well I wasn't really HACKING the websites, because I didn't know the ftp password to get in. But if i knew how to crack passwords, I would have been able to destroy/deface any website through command prompt. An aim buddy gave me his ftp password to his old site, and let me destroy it...it was only for fun, and I was really just looking up commands on the internet :p

I wonder what their using to hack nowadays
