PC Girl: The people who write/discover these exploits have a lot of time on their hands + most of them are very inquisitive people... The link i posted above explains overflows in detail... "Exploit" is far too large of a category to eplain in one post...

Basically, these people look for bugs, trying everything, hoping something will work (or in this case, "not work") btw- a search on exploits brings up AntiOnline.com (where you can find tons of exploits, isn't that funny- to find sploits on a "security" site... + you wont find any patches or papers; on how to patch up holes?)
