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 – cracking WEP with the Hirte attack


  1. Create a WEP access point exactly as in the Caffe Latte attack using the airbase-ng tool. The only additional option is the -N option instead of the -L option to launch the Hirte attack:

  2. Start airodump-ng in a separate window to capture packets for the Wireless Lab Honeypot:

  3. Airodump-ng will now start monitoring this network and storing the packets in Hirte-01.cap file.

  4. Once the roaming client connects to out Honeypot AP, the Hirte attack is automatically launched by airbase-ng:

  5. We start aircrack-ng as in the case of the Caffe Latte attack and eventually the key would be cracked as shown next:

What just happened?

We launched the Hirte attack against a WEP client which was isolated and away from the authorized network. We cracked the key exactly as in the Caffe Latte attack case.

Have a go hero – practice, practice, practice

We would recommend setting different WEP keys on the client and trying this exercise a couple of times to gain confidence...
