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 – creating a monitor mode interface

Let's now set our Alfa card into monitor mode!

Follow these instructions to get started:

  1. Boot into BackTrack with your Alfa card connected. Once you are within the console, enter iwconfig to confirm that your card has been detected and the driver has been loaded properly:

  2. Use the ifconfig wlan0 up command to bring the card up. Verify the card is up by running ifconfig wlan0. You should see the word UP in the second line of the output as shown:

  3. To put our card into monitor mode, we will use the airmon-ng utility which is available by default on BackTrack. First run airmon-ng to verify it detects the available cards. You should see the wlan0 interface listed in the output:

  4. Now enter airmon-ng start wlan0 to create a monitor mode interface corresponding to the wlan0 device. This new monitor mode interface will be named mon0. You can verify it has been created by running airmon-ng without arguments again:

  5. Also, running ifconfig should now display...
