HOW TO CRACK A WI-FI NETWORK’S WEP PASSWORD WITH BACKTRACK

You already know that if you want to lock down your Wi-Fi network, you should opt for WPA encryption because WEP is easy to crack. But did you know how easy? Take a look.

Note: This post demonstrates how to crack WEP passwords, an older and less often used network security protocol. If the network you want to crack is using the more popular WPA encryption, see our guide to cracking a Wi-Fi network's WPA password with Reaver instead.

Today we're going to run down, step-by-step, how to crack a Wi-Fi network with WEP security turned on. But first, a word: Knowledge is power, but power doesn't mean you should be a jerk, or do anything illegal. Knowing how to pick a lock doesn't make you a thief. Consider this post educational, or a proof-of-concept intellectual exercise.

Dozens of tutorials on how to crack WEP are already all over the internet using this method. Seriously—Google it. This ain't what you'd call "news." But what is surprising is that someone like me, with minimal networking experience, can get this done with free software and a cheap Wi-Fi adapter. Here's how it goes.
