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.

Time for action – viewing management, control, and data frames


Now we will learn how to apply filters in Wireshark to look at management, control, and data frames.

Please follow these instructions step by step:

  1. To view all the management frames in the packets being captured, enter the filter wlan.fc.type == 0 into the filter window and hit Enter. You can stop the packet capture if you want to prevent the packets from scrolling down too fast.

  2. To view control frames, modify the filter expression to read wlan.fc.type == 1:

  3. To view data frames, modify the filter expression to wlan.fc.type == 2:

  4. To additionally select a subtype, use the wlan.fc.subtype filter. For example, to view all the beacon frames among all management frames, use the following filter:

    (wlan.fc.type == 0) && (wlan.fc.subtype == 8)
  5. Alternatively, you can right-click on any of the header fields in the middle window and then select Apply as Filter | Selected to add it as a filter:

  6. This will automatically add the correct filter...
