What is a Stack Buffer Overflow? Exploring How To Exploit the Stack

Показать описание
In this video, we'll discuss the basics of software exploitation by beginning with the stack-based buffer overflow. For many, learning how to exploit buffer overflows is the gateway to learning many other exploitation techniques. In addition, you will learn how compilers and modern day operating systems have evolved to mitigate these vulnerabilities.

In this demo, we'll use a sample C program to create a vulnerable program. We'll discuss different compiler flags that we have to use to disable some safety features - mainly stack cookies. Then we'll use IDA Pro to investigate the program and map out the layout of the stack. We'll end this video preparing to study the crash in a debugger.

This will be the first of several videos, so stay tuned as we explore the foundations of software exploitation!
