Kali Linux 2: Windows Penetration Testing

Overview of this book

Microsoft Windows is one of the two most common OS and managing its security has spawned the discipline of IT security. Kali Linux is the premier platform for testing and maintaining Windows security. Kali is built on the Debian distribution of Linux and shares the legendary stability of that OS. This lets you focus on using the network penetration, password cracking, forensics tools and not the OS. This book has the most advanced tools and techniques to reproduce the methods used by sophisticated hackers to make you an expert in Kali Linux penetration testing. First, you are introduced to Kali's top ten tools and other useful reporting tools. Then, you will find your way around your target network and determine known vulnerabilities to be able to exploit a system remotely. Next, you will prove that the vulnerabilities you have found are real and exploitable. You will learn to use tools in seven categories of exploitation tools. Further, you perform web access exploits using tools like websploit and more. Security is only as strong as the weakest link in the chain. Passwords are often that weak link. Thus, you learn about password attacks that can be used in concert with other approaches to break into and own a network. Moreover, you come to terms with network sniffing, which helps you understand which users are using services you can exploit, and IP spoofing, which can be used to poison a system's DNS cache. Once you gain access to a machine or network, maintaining access is important. Thus, you not only learn penetrating in the machine you also learn Windows privilege’s escalations. With easy to follow step-by-step instructions and support images, you will be able to quickly pen test your system and network.

Chapter 6. Password Attacks

Anybody you meet will tell you that weak passwords are responsible for dozens of successful intrusions, both local and remote. As a trained network administrator or security engineer, you have counselled users to make their passwords stronger many times. What you may not be aware of is that many technology professionals make weak passwords or patterns of passwords that endanger not just their own accounts, but the entire network which they maintain. This chapter will show you several tools for testing the passwords on your network, so you can help guide your users to the habit of better passwords:

  • Password Attack Planning

  • Creating or Adapting Password Lists

  • Tools for Creative Password Cracking

  • Meet My Friend Johnny

  • Meet Johnny's Dad, John the Ripper

  • Meet the Ex – xHydra

It is the nature of hashing algorithms to have all hashes be about the same length, and it really doesn't seem any more likely that someone could crack this algorithm as following:
