Hands-On Penetration Testing on Windows

By: Phil Bramwell

Overview of this book

Windows has always been the go-to platform for users around the globe to perform administration and ad hoc tasks, in settings that range from small offices to global enterprises, and this massive footprint makes securing Windows a unique challenge. This book will enable you to distinguish yourself to your clients. In this book, you'll learn advanced techniques to attack Windows environments from the indispensable toolkit that is Kali Linux. We'll work through core network hacking concepts and advanced Windows exploitation techniques, such as stack and heap overflows, precision heap spraying, and kernel exploitation, using coding principles that allow you to leverage powerful Python scripts and shellcode. We'll wrap up with post-exploitation strategies that enable you to go deeper and keep your access. Finally, we'll introduce kernel hacking fundamentals and fuzzing testing, so you can discover vulnerabilities and write custom exploits. By the end of this book, you'll be well-versed in identifying vulnerabilities within the Windows OS and developing the desired solutions for them.

Chapter 10. Windows Shellcoding

I know, describing long hours of trial-and-error tedium as exciting is pretty nerdy. But I think the description is appropriate when it comes to shellcoding. I still remember the first time I got root on a Linux target with a carefully crafted overflow and some shellcode. I literally yelped when I saw the shell! Chapter 7Stack and Heap – Memory Management, was a nice introduction to the buffer overflow concept and shellcoding fundamentals, but there was something missing that made it less yelp-worthy. That's right: we were using a vulnerable C program with a main function very similar to countless other introductory demonstrations of the concept. We even disabled security measures to make it work. It felt like we were sitting in the classroom wondering when we'd use this stuff in the real world. I felt like a teenager again, but not in a good way. Have no fear, for this chapter will give us a taste of real-world analysis and attacks. We'll start by introducing...
