Hey there, I've been looking around the internet about security and hacking (no illegal intensions) and have found myself nowhere. There is just so much information about computer systems but none have seemed to base any weaknesses or what purposes do they hold. All I've been told is something about bouncing from dial-up computers so you wont get caught and even though it was in the newbies section, I failed to understand it.
For a while now I've been interested in not knowing anything at all to becoming "3L337" but im sure they've, at one time or another, have started to where I am. But where did they start?

P.S. I have no illegal intentions, I just thirst for this knowledge for my own ability to understand everything.
