How to Crack a Wi-Fi Network’s WEP Password using BackTrack
Hopefully you know you should use WPA to secure your Wi-Fi network, always select WPA encryption over WEP as the later is so easy to crack. How easy is it? Check out the video I posted below.
Yhis video will walk you through the procedures, step by step showing you how to crack a Wi-Fi network with WEP security turned on. Before we go on let me add a few words about why I am doing this. First off this is for educational purposes only and to help you understand how vulnerable you really are with a WEP encrypted network. So don’t be a jackass and use this newly founded knowledge for anything illegal.
I started not to write about this topic knowing that someone might take this information and use it for the wrong reasons. However the good far out weighed the bad, besides there are so many tutorials on how to crack WEP all over the Internet using this very same method.
Cracking WEP can be done with free software and a cheap Wi-Fi adapter, chances are you don’t have the tools needed for this job. Heres what you need to crack WEP.
1. You are going to need a wireless adapter that’s capable of packet injection, most likely you do not have one. I got mine from Amazon which is on sale now for $39.00, the model I purchased is a Alfa AWUS050NH USB adapter, pictured above. If you don’t like the one I have there are tons of resources on the Internet for getting aircrack-compatible adapters. If you think that yours might be one that will work check out this Tutorial: Is My Wireless Card Compatible?
2. A BackTrack 3 Live CD. Download a copy of the CD and burn it, or load it up in VMware to get started. BackTrack 4 pre-release is available but I would stick with what we know works which is version 3.
3. A active WEP-enabled Wi-Fi network with a strong signal and hopefully with users connecting and disconnecting their devices from the network. The busy network while you harvest the data to run the crack, the better your chances of success.
4. This is an ten-step process that requires typing in some long commands and waiting around for your Wi-Fi card to collect data in order to crack the password. Having a little patience will go a long way here.
