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.

Summary


In this chapter, we explored some basic cryptography attacks. We started with cipher block chaining bit-flipping and learned how to modify the initialization vector in a predictable fashion. Once this was demonstrated, we leveraged the information to compromise the lab server. We then explored hash length extension attacks, exploiting flaws in message verification methods by leveraging the core compression functionality of the hash algorithm to produce an attacking hash that will pass verification. To prepare for this demonstration, we installed a powerful web and database server stack on Kali to host a vulnerable web app for legal study and testing in our home lab. We exploited the same lab environment in the final section on padding oracle attacks, which built upon the core knowledge introduced earlier in the book.
