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.

Network pivoting with Metasploit


We'll start with a basic example of pivoting into a hidden network. Let's suppose you've social-engineered your way into an office building and you find one of the open conference rooms. There are network drops throughout the room, so you sit down and plug right in. Unfortunately, you don't get far: it's a conference room that is often used for presentations with guests and business partners, so IT has decided to segregate it away from their internal resources. You poke around with Netdiscover and find just one machine on the LAN:

You continue your enumeration by scanning other private address ranges, including subnets inside 10.0.0.0/8, but you find no other hosts. You're stuck on 192.168.63.0/24. After some footprinting, you find that the other machine on the LAN is a Vista Business box – now we're in business! (See what I did there?)

I'll leave the details to your imagination, but let's jump ahead to getting a malicious reverse TCP payload on the host. I...
