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.

Time for action – discovering wireless devices

Follow the given instructions to get started:

  1. Create a monitor mode interface using your card as shown in the following screenshot:

  2. Use airodump-ng to start scanning the airspace. Ensure that channel hopping happens across both the 802.11 b and g bands:

  3. Move around the premises to get as many clients and access points as possible:

  4. Request from the system administrator of the company a list of MAC addresses for all access points and wireless clients. This will help us in the next phase:

What just happened?

We took a scan of the entire wireless network in the area. This now gives us a clear idea about what is in the air. This is the starting point of the exercise. Now we will analyze this dump and do an actual penetration attack in the Attack phase.


Now that we understand what is in the airspace of the authorized network, we need to break the problem into smaller parts.

In our attacking phase, we will explore the following:

  • Finding rogue access...
