Buffer Overflows, don't let the name scare you. Before I did my OSCP training that's all I had in mind. I was truly terrified of them. but once you dig in you'll see how easy it is I literally solved the questions in the book and learned it in 6 hours. when you do your OSCE, and get into ASLR And DEP bypass. that's where you need to be afraid...be very afraid..
