This article guides how to crack the WPA or WPA2 password. All you need is the live CD of the Backtrack version 5. Many of us has used backtrack to crack WPE but this time Backtrack has made it possible to crack the WPA too. It’s really easy and fun to crack the WPA but all you need is the patience.
Before starting into the steps below is the link to download the backtrack5 .
Get Backtrack 5
Follow the following steps:
Step 1: Boot the PC with the backtrack dvd.
Step 2: when boot is complete type following to start the GUI mode.
startx
Step 3: Then you must install Reaver. To install the Reaver simply type the below code into the terminal
apt-get install reaver
Step 4: Now assuming you have successfully installed the reaver let me descride further steps. Before cracking the Wifi, you must know the BSSID of router you want to crack. BSSID is the code that uniquely represent’s the Router.In order to know the BSSID type following command
wconfig
and note the code in wlan0. During Cracking you must keep your network card in monitor mode. To do so type following command
airmon-ng start wlan0
This command will output the name of monitor mode interface which is usally mon0.
finally to find the BSSID of the victim router use following command :
airodump-ng wlan0
[note:if wlan0 does not work you can also use monitor interface i.e use mon0.]
this command will output the list of wireless network in range. when you see the network you desired to crack note the BSSID of that network.
Step 5: With the BSSID of the victim router start the reaver inorder to crack it
now enter the following command in terminal
reaver -i moninterface -b bssid -vv
[note: use monitor interface i.e mon0 usally and victim's BSSID in bssid in above command ]
Step 6: All you must do now is wait with patience and let reaver do it’s work.Reaver takes about 2.5 to 5 hours to crack the code. When successfully cracked it display’s the WPA decrypted code in WPA PSK section .
Enjoy cracking Wifi’s.
