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 have made some key observations about WLAN protocols.

Management, control, and data frames are unencrypted and thus can be easily read by someone who is monitoring the airspace. It is important to note here that the data packet payload can be protected using encryption to keep it confidential. We will talk about this in the next chapter.

We can sniff the entire airspace in our vicinity by putting our card into monitor mode.

As there is no integrity protection in management and control frames, it is very easy to inject these packets by modifying them or replaying them as-is using tools such as aireplay-ng.

Unencrypted data packets can also be modified and replayed back to the network. If the packet is encrypted, we can still replay the packet as-is, as WLAN by design does not have packet replay protection.

In the next chapter, we will look at different authentication mechanisms that are used in WLANs such as MAC filtering and shared authentication, and understand the...
