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 – setting up the AP with FreeRadius-WPE


Follow the given instructions to get started:

  1. Connect one of the LAN ports of the access point to the Ethernet port on your machine running BackTrack. In our case, the interface is eth1. Bring up the interface and get an IP address by running DHCP as shown in the following screenshot:

  2. Log in to the access point and set the Security Mode to WPA-Enterprise. Then, under the EAP (802.1x) section, enter the RADIUS server IP Address as 192.168.0.198. This is the same IP address allocated to our wired interface in step 1. The RADIUS server Shared Secret would be test as shown in the following screenshot:

  3. Let us now open a new terminal and go to the directory /usr/local/etc/raddb. This is where all the FreeRadius-WPE configuration files are:

  4. Open eap.conf, you will find that the default_eap_type is set to peap. Let us leave this as it is:

  5. Open clients.conf. This is where we define the allowed list of clients that can connect to our RADIUS server...
