About the Author
Vivek Ramachandran has been working on Wi-Fi Security since 2003. He discovered the Caffe Latte attack and also broke WEP Cloaking, a WEP protection schema publicly in 2007 at Defcon. In 2011, Vivek was the first to demonstrate how malware could use Wi-Fi to create backdoors, worms, and even botnets.
Earlier, he was one of the programmers of the 802.1x protocol and Port Security in Cisco's 6500 Catalyst series of switches and was also one of the winners of the Microsoft Security Shootout contest held in India among a reported 65,000 participants. He is best known in the hacker community as the founder of http://www.SecurityTube.net/ where he routinely posts videos on Wi-Fi Security, Assembly Language, Exploitation Techniques, and so on. SecurityTube.net receives over 100,000 unique visitors a month.
Vivek's work on wireless security has been quoted in BBC online, InfoWorld, MacWorld, The Register, IT World Canada, and so on. This year he is speaking or training at a number of security conferences, including BlackHat, Defcon, Hacktivity, 44con, HITB-ML, Brucon, Derbycon, HashDays, SecurityZone, SecurityByte, and so on.
I would like to thank my lovely wife for all the help and support during the book's writing process; my parents, grandparents, and sister for believing in me and encouraging me for all these years, and last but not the least, I would like to thank all the users of SecurityTube.net who have always been behind me and supporting all my work. You guys rock!

Preface
Wireless Networks have become ubiquitous in today's world. Millions of people use them worldwide every day at their homes, offices, and public hotspots to log on to the Internet and do both personal and professional work. Even though wireless makes life incredibly easy and gives us such great mobility, it comes with its risks. In recent times, insecure wireless networks have been exploited to break into companies, banks, and government organizations. The frequency of these attacks has only intensified, as the network administrators are still clueless on how to secure wireless in a robust and foolproof way.
BackTrackWirelessPenetrationTesting: Beginner's Guide is aimed at helping the reader understand the insecurities associated with wireless networks, and how to conduct penetration tests to find and plug them. This is an essential read for those who would like to conduct security audits on wireless networks and always wanted a step-by-step practical guide for the same. As every wireless attack explained in this book is immediately followed by a practical demo, the learning is very complete.
We have chosen BackTrack as the platform to test all the wireless attacks in this book. BackTrack, as most of you may already be aware, is the world's most popular penetration testing distribution. It contains hundreds of security and hacking tools, some of which we will use in this course of this book.
What this book covers
, Wireless Lab Setup , introduces dozens of exercises that we will be doing in this book. In order to be able to try them out, the reader will need to set up a wireless lab. This chapter focuses on how to create a wireless testing lab using off the shelf hardware and open source software. We will first look at the hardware requirements which include wireless cards, antennas, access points, and other Wi-Fi-enabled devices, then we will shift our focus to the software requirements which include the operating system, Wi-Fi drivers, and security tools. Finally, we will create a test bed for our experiments and verify different wireless configurations on it.
