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 – session hijacking over wireless

  1. Set up the test exactly as in the Man-in-the-Middle attack lab. On the victim let's fire up the browser and type in "". Let us use Wireshark to monitor this traffic. Your screen should resemble the following:

  2. Apply a Wireshark filter for DNS and as we can see, the victim is making DNS requests for "":

  3. In order to hijack the browser session we will need to send fake DNS responses which will resolve the IP address of "" to the hacker machine's IP address The tool we will use for this is called Dnsspoof and the syntax is dnspoof –i mitm-bridge:

  4. Refresh the browser windows and now as we can see through Wireshark, as soon as the victim makes a DNS request for any host (including, Dnsspoof replies back:

  5. On the victim machine, we see an error which says "Connection Refused". This is because we have made the IP address for as which is the hacker machine's IP, but there...
