Tutorial: How to Crack WEP on a Mac

I was talking with a friend at a party who lost his internet connection recently. His previous connection was a neighbor’s open wifi. Unfortunately, the access point disappeared one day and all the rest were password protected. I mentioned I knew how to crack those. Naturally, he asked if I could crack one for him. I enjoy a challenge and being helpful, so I agreed. I told him to check if there were any WEP protected networks near him when he got home. He emailed me saying there were a few, and I scheduled a time to make the house call.
The first time I learned how to crack WEP was after reading about it on one of my nerd news feeds. Back then, the process involved running several commands from the command line. I decided to do some more homework on WEP cracking before I went to his house. It turns out nowadays it has gotten a lot easier.
So I took my two girls with me on my house call along with a MacBook, a Hawking HWUG1 USB WiFi adapter, and a BackTrack 3 live CD. When we got there, I booted the MacBook from the BackTrack live CD and plugged in the USB Wifi adapter. I started Kismet to scan for a WEP protected access point with the strongest signal. Then I ran SpoonWEP and was able to get the WEP key in under 2 minutes.
My friend and his wife can finally get back on the internet after several weeks of being offline. They recently had a baby, so she stays home and can now get back to searching for a new place to live via the internet.
The rest of the night was filled with catching up, watching Shrek 2, eating Chinese food, and looking through old photo albums. Good times. They also slipped some gas money into my pocket right before we left which was very thoughtful.
I think I’ll put up a short tutorial soon with the exact steps I take to crack WEP.
