Around that age i got my pc privileges revoked. "Grounded" was how it was referred.
My parents both were tech savy. I managed to download a keylogger and swipe the login password before end of first week of punishment. I had access for HW, strictly hw. That's when i made a move. By 12 i had custom .exe made but god knows who with GUI capable of ddos among other nettools i shouldn't have had. Nobody taught those things to me. It just happened. Had the idea probably from a movie or tv..
