Crack Wi-Fi passwords, WPS Hack Method

Hacking Wi-Fi networks with the brute force and dictionary attacks is not easy. I tried these many times without any success. Now I find a working alternative method to hack Wi-Fi networks which is comparatively easy. But you need to have WPS enabled Wi-Fi devices around you.

 

Its not legal to hack Wi-Fi networks without the permission of the owner of the device. I insist not to use this method for getting free internet from your neighbors internet connection .
 

Reqtirements:

1. Laptop
2. Back track boot-able pen drive

Back track is Linux distro mainly used for hacking. Backtrack 5 contains tools for someone without much knowledge of hacking can use to try simple things.
I am not going to tell how to make Back track boot-able pen drive follow the below link if you want.

Once you boot through USB you will be logged in to command prompt,then check  your network interface details using ifconfig command . Out put should be something like below.

 

Now you have to start your Wi-Fi card in monitor mode. Use the following command to set it in monitor mode

airmon-ng start wlan0

Now you can check again using “ifconfig” command, a new interface mon0 will be created. You can see it in the out put.

 

Now we have to scan the air for the WPS enabled networks use the wash command for this.

 

wash -i mon0

 

If you found that WPS locked is:no you are good to go.  In this case two devices are with WPS enabled.

We will crack the key of first detected device, we have to use the reaver command as shown below to crack the password

reaver –i mon0 –b (macid of the device) –vv

 

 

After few minutes to few hours (can take up to 10 to 15 hours) you will see the output like the below

 

Now Wi-Fi Password is cracked along with PIN, if user changes the Wi-Fipassword you don’t need to do this all again for hours you just simply crack the password using the WPS PIN as show below .

New password will be retrieved in 3 or 4 seconds.

To avoid somebody hack in to your device I strictly advice you to disable WPS from your router settings.
