Actually buffer overflows in general is just inserted input. It goes on to a point where memory becomes corrupt and when that happends things tend to overwrite... the egg is usually reffered to what will replace the value of the variable in the program or whatever.

What do they use to use the exploits? (Like, how do you know if theres a security hole that they can use an expliot for?)
Well you generally use a compiler or an interpreter to aid you on your quests to "point click and FIRE!". To actually find a vulnerability I've already posted what you need and Gore has basicly repeated what has already been said .

Oh and I am a hacker.... not a cracker
Either way... folks who tend to want to fit in or attempt to try to push others into your (class of people) are generally annoying. These peaple care more about a socialized ranking or being appart of something big more than the very computers and computer related hobbies which gives them the excuse to be appart of it all. Agian... guys like that really should do something about their whole inferiority complex thing.
