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.

Security best practices for Enterprises


We have seen a ton of attacks against WPA/WPA2, both Personal and Enterprise. Based on our experience, we would recommend the following:

  1. For SOHOs and medium-sized businesses, use WPA2-PSK with a strong passphrase. You have up to 63 characters at your disposal. Make use of it.

  2. For large enterprises, use WPA2-Enterprise with EAP-TLS. This uses both client and server-side certificates for authentication, and currently is unbreakable.

  3. If you have to use PEAP or EAP-TTLS with WPA2-Enterprise, then ensure that certificate validation is turned on, the right certifying authorities are chosen, the Radius servers that are authorized are used and finally any setting that allows users to accept new Radius servers, certificates, or certifying authorities is turned off.

Pop quiz – attacking WPA-Enterprise and RADIUS

  1. FreeRadius-WPE is a:

    1. Radius server written from scratch

    2. Patch to the FreeRadius server

    3. Ships by default on all Linuxes

    4. None of the above

  2. PEAP can be attacked...
