In this post i will show you a book Wireless Wep Key Hacking where the author gives you a step by step approach to breaking a WEP key. The entire attack is done with publicly available software and doesn't require special hardware.
The author of this book is Haider Afridi, an expert into the field of hacking and security. This book is a complete guide of hacking WEP keys, and the best part of this e-book is that he has written it in such a manner that even a 5th grade kid can understand it.
I have personally hacked more than 10 wirelesses using the method presented in this book.
