Mastering Kali Linux Wireless Pentesting

By: Brian Sak, Jilumudi Raghu Ram

Overview of this book

Kali Linux is a Debian-based Linux distribution designed for digital forensics and penetration testing. It gives access to a large collection of security-related tools for professional security testing - some of the major ones being Nmap, Aircrack-ng, Wireshark, and Metasploit. This book will take you on a journey where you will learn to master advanced tools and techniques to conduct wireless penetration testing with Kali Linux. You will begin by gaining an understanding of setting up and optimizing your penetration testing environment for wireless assessments. Then, the book will take you through a typical assessment from reconnaissance, information gathering, and scanning the network through exploitation and data extraction from your target. You will get to know various ways to compromise the wireless network using browser exploits, vulnerabilities in firmware, web-based attacks, client-side exploits, and many other hacking methods. You will also discover how to crack wireless networks with speed, perform man-in-the-middle and DOS attacks, and use Raspberry Pi and Android to expand your assessment methodology. By the end of this book, you will have mastered using Kali Linux for wireless security assessments and become a more effective penetration tester and consultant.

The Metasploit CTS/RTS flood attack

In a wireless medium, collisions can degrade the performance of the network. In order to avoid collisions, clients transmitting at the same time, wireless clients, and access points use CTS/RTS, clear to send, and request to send frames before transmitting data. Whenever a wireless client wants to send data, it reserves the medium by sending RTS/CTS frames. In simple terms, when a wireless client is about to send some data, it notifies other devices on the network that it's going to send data and asks others to wait for some time before attempting to transmit themselves. Other stations respect the announcement and wait until the transfer is complete. An attacker can use these unauthenticated frames and create a denial of service condition on the target network.

By continuously sending RTS/CTS frames to other devices on the wireless network, the attacker tries to reserve the medium, thus creating an idle network. In practice, this does not ultimately lead...
