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 – conducting the Caffe Latte attack

Follow these instructions to get started:

  1. Let us first set up our legitimate access point with WEP for the network Wireless Lab with the key ABCDEFABCDEFABCDEF12 in Hex:

  2. Let us connect our client to it and ensure that the connection is successful using airodump-ng as shown next:

  3. Let us unplug the access point and ensure the client is in the un-associated stage and searching for the WEP network Wireless Lab:

  4. Now we use airbase-ng to bring up an access point with Wireless Lab as the SSID with the parameters shown next:

  5. As soon as the client connects to this access point, airbase-ng starts the Caffe-Latte attack as shown:

  6. We now start airodump-ng to collect the data packets from this access point only, as we did before in the WEP-cracking case:

  7. We also start aircrack-ng as in the WEP-cracking exercise we did before to begin the cracking process. The command line would be aircrack-ng filename where filename is the name of the file created by airodump...
