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.

Maintaining access with Ncat


NetCat (Ncat) is a little known yet powerful tool designed to make raw socket connections to network ports. It's a small tool designed to run from one executable file that is easily transferred to a system and can also be renamed to anything to hide the executable within an operating system. Ncat will call back to an attacking server with only user-level access. Ncat is an open source application brought to you by insecure.org, the same fine folks that maintain NMap. Ncat, and its older cousin, nc, both come installed on Kali. Ncat is bundled with any install of NMap.

Actually, as mentioned previously, there are two versions of Ncat. The older version's executable is nc. Nc will also make raw socket connections to any TCP/UDP ports:

The big advantage of Ncat is that it supports SSL encryption, where all of nc's traffic is in clear text. Nc's traffic can sometimes be picked up by IDS/IPS and other security devices. Ncat's traffic can be encrypted and hidden to...
