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.

John the Ripper (command line)


John the Ripper is the application that underlies Johnny. You may be like us, and be more comfortable on the command line than in a GUI when using the password cracking tools, like John the Ripper. You may go for the CLI because it uses fewer resources than the GUI, or because you are working through a ssh connection to a server without a GUI interface. It is easy to use John the Ripper, and there are a lot more options and ways to use John by using the command lines that have not yet been added to Johnny.

You can see all the various hashing algorithms supported by John and test the speed of your system for cracking by running the following command:

john –test

This will run through all the various hashing algorithms supported by John and give you the time it will take for the various hashes. The following image shows the read-out from the test flag:

We're going to run John against a set of hashes obtained from an earlier exploitation of a system. Note the flags...
