BackTrack 5 Wireless Penetration Testing Beginner's Guide

By: Vivek Ramachandran

Overview of this book

Wireless has become ubiquitous in today’s world. The mobility and flexibility provided by it makes our lives more comfortable and productive. But this comes at a cost – Wireless technologies are inherently insecure and can be easily broken. BackTrack is a penetration testing and security auditing distribution that comes with a myriad of wireless networking tools used to simulate network attacks and detect security loopholes. Backtrack 5 Wireless Penetration Testing Beginner’s Guide will take you through the journey of becoming a Wireless hacker. You will learn various wireless testing methodologies taught using live examples, which you will implement throughout this book. The engaging practical sessions very gradually grow in complexity giving you enough time to ramp up before you get to advanced wireless attacks.This book will take you through the basic concepts in Wireless and creating a lab environment for your experiments to the business of different lab sessions in wireless security basics, slowly turn on the heat and move to more complicated scenarios, and finally end your journey by conducting bleeding edge wireless attacks in your lab.There are many interesting and new things that you will learn in this book – War Driving, WLAN packet sniffing, Network Scanning, Circumventing hidden SSIDs and MAC filters, bypassing Shared Authentication, Cracking WEP and WPA/WPA2 encryption, Access Point MAC spoofing, Rogue Devices, Evil Twins, Denial of Service attacks, Viral SSIDs, Honeypot and Hotspot attacks, Caffe Latte WEP Attack, Man-in-the-Middle attacks, Evading Wireless Intrusion Prevention systems and a bunch of other cutting edge wireless attacks.If you were ever curious about what wireless security and hacking was all about, then this book will get you started by providing you with the knowledge and practical know-how to become a wireless hacker.

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 air space. 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 which are used in WLANs such as MAC Filtering, Shared Authentication, and so on, and understand...
