Fisrt off, I wasnt talikng to the admin as I have great respect for shabbir, secondly buffer overflow or smashing the stack causes a program to crash or operate incorrectly, the aim is then to inject executable code into the running program and then to try and take control of the process. It is a very old method but it still works on some systems. All I meant by that is to try that with the facebook server which is very dangerous in my eyes as you are very likely to get caught. I hope you understand me now?
