Kali Linux is the distro, which comes to mind when anyone thinks about penetration testing. Every year Kali is improved and updated with new tools making it more powerful. We see new exploits being released every day and with rapidly evolving technology, we have rapidly evolving attack vectors. This book aims to cover the approach to some of the unique scenarios a user may face while performing a pentest.
This book specifically focuses on using the Kali Linux to perform a pentest activity starting from information gathering till reporting. This book also covers recipes for testing wireless networks, web applications, and privilege escalations on both Windows and Linux machines and even exploiting vulnerabilities in software programs.
Chapter 1, Kali – An Introduction, covers installing of Kali with different desktop environments, and tweaking it a bit by installing a few custom tools.
Chapter 2, Gathering Intel and Planning Attack Strategies, covers recipes about collecting subdomains and other information about a target using multiple tools, such as Shodan, and so on.
Chapter 3, Vulnerability Assessment, talks about the methods of hunting for vulnerabilities on the data discovered during information gathering process.
Chapter 4, Web App Exploitation – Beyond OWASP Top 10, is about the exploitation of some of the unique vulnerabilities, such as serialization and server misconfiguration, and so on.
Chapter 5, Network Exploitation on Current Exploitation, focuses on different tools, which can be used to exploit vulnerabilities in a server running different services, such as Redis, MongoDB and so on, in the network.
Chapter 6, Wireless Attacks – Getting Past Aircrack-ng, teaching you some new tools to break into wireless networks, as well as using aircrack-ng.
Chapter 7, Password Attacks – The Fault in Their Stars, talks about identifying and cracking different types of hashes.
Chapter 8, Have Shell, Now What? covers different ways of escalating privilege on Linux and Windows-based machines and then getting inside that network using that machine as a gateway.
Chapter 9, Buffer Overflows, discusses exploiting different overflow vulnerabilities, such as SEH, stack-based overflows, egg hunting, and so on.
Chapter 10, Playing with Software-Defined Radios, focusses on exploring the world of frequencies and using different tools to monitor/view data traveling across different frequency bands.
Chapter 11, Kali in Your Pocket – NetHunters and Raspberries, talks about how we can install Kali Linux on portable devices, such as Raspberry Pi or a cellphone, and perform pentest using it.
Chapter 12, Writing Reports, covers the basics of writing a good quality report of the pentest activity once it has been performed.
The OS required is Kali Linux with at least 2 GB of RAM recommended and 20-40 GB of hard disk space.
The hardware needed for the device would be a RTLSDR device for Chapter 10, Playing with Software-Defined Radios and any of the devices mentioned in the following link for Chapter 11, Kali in Your Pocket – NetHunters and Raspberries:

We also require Alfa card for Chapter 6, Wireless Attacks – Getting Past Aircrack-ng.
This book is aimed at IT security professionals, pentesters and security analysts who have basic knowledge of Kali Linux and want to conduct advanced penetration testing techniques.
In this book, you will find several headings that appear frequently (Getting ready, How to do it…, How it works…, There's more…, and See also). To give clear instructions on how to complete a recipe, we use these sections as follows:
This section tells you what to expect in the recipe, and describes how to set up any software or any preliminary settings required for the recipe.
This section usually consists of a detailed explanation of what happened in the previous section.
This section consists of additional information about the recipe in order to make the reader more knowledgeable about the recipe.
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "To launch fierce, we type fierce -h
to see the help menu."
A block of code is set as follows:
if (argc < 2) { printf("strcpy() NOT executed....\n"); printf("Syntax: %s <characters>\n", argv[0]); exit(0); }
Any command-line input or output is written as follows:
fierce -dns host.com -threads 10
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "We right-click and navigate to Search for
| All commands in all modules
."
