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 – Rogue access point

Follow these instructions to get started:

  1. Let us first bring up our Rogue access point using airbase-ng and give it the ESSID Rogue:

  2. We now want to create a bridge between the Ethernet Interface which a part of the authorized network and our Rogue access point interface. To do this we will first create a bridge interface and name it Wifi-Bridge:

  3. We will then add both the Ethernet and the at0 virtual interface created by airbase-ng to this bridge:

  4. We will then bring with these interfaces up to bring the bridge up"

  5. We will then enable IP forwarding in the kernel to ensure packets are forwarded:

  6. Brilliant! We are done. Now any wireless client connecting to our Rogue access point will have full access to the authorized networking using the wireless-to-wired "Wifi-Bridge" we just built. We can verify this by first connecting a client to the Rogue access point. Once connected, if you are using Vista, your screen might look like the following:

  7. We will notice it receives...
