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.

Summary


In this chapter, we learnt about WLAN authentication. Hidden SSIDs are a security-through-obscurity feature and are relatively simple to beat. MAC address filters do not provide any security, as MAC addresses can be sniffed from the air from the wireless packets. This is possible because the MAC addresses are unencrypted in the packet. Open Authentication provides no real authentication at all. SKA is a bit tricky to beat but, with the help of the right tools, we can derive the store and the keystream, using which it is possible to answer all future challenges sent by the access point. The result is that we can authenticate without needing to know the actual key.

In the next chapter, we will take a look at different WLAN encryption mechanisms—WEP, WPA, and WPA2—and look at the insecurities that plague them.
