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.

My friend Johnny


First we will talk about my friend Johnny. Johnny is a GUI frontend for my other friend John. For most password cracking tasks, this is an easy way to use Johnny. It uses the normal defaults for most password cracking sessions. Once you have captured some hashes, save them to a text file and open Johnny. As shown in the following image, Johnny can be found under Applications | 05 – Password Attacks | johnny:

Getting to Johnny in Kali 2.x is simpler. See the following image:

We are using the password hashes from a previous exploit earlier in the book, where we were passing the hash. We have shortened the list to only include the hashes of the two accounts that we think have critical access to the networked systems:

Once Johnny is open, click on the Open Passwd File button and pick the text file where you have saved the user's hash values. This will load the file into Johnny.

Tip

Hacker Note:

It is best to delete the Guest and any other user account that you do not want to crack...
