This book demonstrates how to perform a successful wireless assessment utilizing a selection of open source tools. Readers, from beginners to seasoned professionals, will gain an understanding of the tools and techniques used to discover, crack, and exploit wireless networks as well as learn how to extract sensitive information from the wireless traffic and the clients themselves. Wireless networks are nearly always in scope as part of a comprehensive security assessment and require special consideration and a different skill set than other aspects of the assessment. You will learn the language and technologies that differentiate 802.11 networks and be introduced to the specialized applications used to test them. This book is built around gaining hands-on experience with Kali Linux, and each chapter contains many step-by-step examples on the use and mastery of the wireless assessment tools included with this distribution.
Chapter 1, Wireless Penetration Testing Fundamentals, introduces you to the hardware, software, and terminology associated with wireless penetration tests. It guides you through deploying Kali and verifying your wireless hardware required to conduct a successful wireless assessment.
Chapter 2, Wireless Network Scanning, covers the steps that are to be performed in order to discover, identify, and catalog wireless networks and clients that are in the scope of your penetration test.
Chapter 3, Exploiting Wireless Devices, describes weaknesses that may be present in the wireless equipment itself and tools and techniques you can use to exploit these weaknesses.
Chapter 4, Wireless Cracking, digs into the interception of wireless key exchanges and authentication between the clients and the infrastructure. It also shows you practical techniques to crack these various security mechanisms and expose the encrypted data transmissions.
Chapter 5, Man-in-the Middle Attacks, explains and demonstrates ways to extract sensitive information from the clients who are using the wireless infrastructure by enabling you to intercept their traffic and manipulate critical network resources.
Chapter 6, Man-in-the Middle Attacks Using Evil Twin Access Points, expands on the previous chapter by showing you techniques to set up a parallel wireless infrastructure to emulate the production network. This enables additional attacks against the clients utilizing the wireless network.
Chapter 7, Advanced Wireless Sniffing, covers the use of traffic captures and decryption as a means to extract sensitive information from the data that is traversing the wireless network. Tools and techniques used to collect and analyze the data are provided.
Chapter 8, Denial of Service Attacks, discusses the use of targeted or broad disruptions in the performance or availability of the wireless network as an element of a wireless assessment.
Chapter 9, Wireless Pen-Testing from Non-Traditional Platforms, expands upon the previous chapters and introduces additional hardware and software platforms that can be used during a wireless assessment, including Raspberry Pi and Android devices.
This book covers the use of Kali Linux to conduct wireless penetration tests. The theory and explanations of the wireless technologies and applications are covered in each of the chapters; however, if you'd like to follow along with the provided examples, you will need some equipment. Chapter 1, Wireless Penetration Testing Fundamentals covers the hardware and software requirements for a wireless penetration test and should be sufficient to provide a list of prerequisites for the chapters that follow. In general, you will need a laptop running the Kali Linux distribution and a supported wireless adapter to follow along with the activities and tests described in this book.
This book is intended for security professionals who actively conduct security assessments or penetration tests for their clients and would like to learn more about the security considerations for wireless network environments. This book will also be useful for those looking to get into the information security profession as it walks the reader step by step through many scenarios that are common when assessing wireless security.
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: "The
iw command is used to show or manipulate wireless devices and their configurations."
A block of code is set as follows:
<html> <body> <h1>CSRF Payload</h1> <form action="http://10.0.0.1/remote_management.php"; method="POST"> <input type="hidden" name="http_port" value="8080" /> <input type="hidden" name="http" value="enabled" /> <input type="hidden" name="single" value="any" /> <input type="submit" value="Submit request" /> </form> </body> </html>
Any command-line input or output is written as follows:
#apt-get update #apt-get upgrade
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 will now import the new image into VirtualBox. Navigate to File | Import Appliance… from the VirtualBox application."
