Kali Linux Wireless Penetration Testing Beginner???s Guide - Third Edition

By: Cameron Buchanan, Daniel W. Dieterle, Vivek Ramachandran

Overview of this book

As wireless networks become ubiquitous in our lives, wireless penetration testing has become a key skill in the repertoire of the professional penetration tester. This has been highlighted again recently with the discovery of the KRACK attack which enables attackers to potentially break into Wi-Fi networks encrypted with WPA2. The Kali Linux security distribution comes with a myriad of tools used for networking attacks and detecting security loopholes. Kali Linux Wireless Penetration Testing Beginner's Guide, Third Edition has been updated to Kali Linux 2017.3 with the latest methodologies, including full coverage of the KRACK attack and how to defend against it. The book presents wireless pentesting from the ground up, introducing all elements of penetration testing with each new technology. You'll learn various wireless testing methodologies by example, from the basics of wireless routing and encryption through to detailed coverage of hacking methods and attacks such as the Hirte and Caffe Latte.

Revisiting WLAN frames


As this book deals with the security aspects of wireless, we will assume that you already have a basic understanding of the protocol and the packet headers. If not, or if it's been some time since you worked on wireless, this would be a good time to revisit this topic again.

Let's now quickly review some basic concepts of WLANs that most of you may already be aware of. In WLANs, communication happens over frames. A frame would have the following header structure:

The Frame Control field itself has a more complex structure:

The Type field defines three types of WLAN frame:

  • Management frames: Management frames are responsible for maintaining communication between access points and wireless clients. Management frames can have the following subtypes:

    • Authentication

    • Deauthentication

    • Association request

    • Association response

    • Reassociation request

    • Reassociation response

    • Disassociation

    • Beacon

    • Probe request

    • Probe response

  • Control frames: Control frames are responsible for ensuring a proper...
