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 3: Windows Passwords on the Network


  1. False; all outputs are fixed length, so there's a unique hash value for a null input.
  2. Avalanche.
  3. The LM hash password is actually two 7-character halves concatenated; the LM hash password is not case-sensitive.
  4. The server challenge is randomly generated and used to encrypt the response, so every challenge would result in a different network hash for the same password.
  5. NetBIOS Name Service.
  6. False; the opposite is true.
  7. mask==?d?d?s[Q-Zq-z][Q-Zq-z]
  8. False; the tool is called John the Ripper.
