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.

Cracking the NAC (Network Access Controller)


These days, Network Access Controller (NAC) appliances are becoming more common on networks. NACs do give an increased level of security, but they are not the "end all" solution that their vendors' marketing and sales materials suggest that they are. We will show you a simple method of bypassing NAC controls on a company network.

The following information comes from a real hack to a real company we performed a while back. Of course, all the names and IP addresses have been changed to protect the company. This is not theory. This is a real world hack. The good thing for the company in this dramatization is that we are the good guys. The sad thing is that it only took about 30 minutes to figure this out, and maybe two hours to fully implement it.

We will be bypassing the NAC for the company widgetmakers.com. Widget Makers has two networks: one the corporate LAN (CorpNET), and the other a production network (ProdNET), containing classified data. The...
