Mastering Kali Linux Wireless Pentesting

By: Sak, 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 fake beacon flood attack


Beacon frames are sent by access points at regular intervals, and client stations also send beacon frames when they are participating in ad hoc mode. A beacon frame contains important information about the network capabilities, such as channel information, timestamp, and configured SSIDs. Wireless clients can detect the presence of access points by listening for the beacon frames transmitted from Ops. They gather the information in Beacon frames to determine which networks are available and which access point to connect to. Typically, clients will choose to connect to an access point with a strong signal strength when all the other capabilities of the access point are equal. In this attack, an attacker fakes these beacon frames and sends them in large numbers to confuse the wireless clients; sometimes, this may make things difficult or prevent the wireless clients from connecting to their preferred networks.

In this attack scenario, we explore the fake beacon...
