Hack Wi-Fi by breaking the WPS pin

Required tools:

1. Kali as VM or you can make a bootable USB of KALI - If you prefer the former, you would need to invest in a wireless network card with an Atheros chipset. I personally use Alpha AWUS036NHA but I’ve heard TP-LINK TL – WN722N VERSION 1 (only) works fine too.
2. A WPS enabled router

Procedure:

Step 1: Enable Monitor mode on your network Card

Your network card usually works on managed mode which captures packets directed to your computer. But by turning on Monitor mode you Network will be able to capture all packets around you which includes packets which are not destined to you.

There are two ways to do this:

Method 1:-

iwconfig,

ifconfig (interface) down,  

iwconfig (interface) mode monitor

ifconfig {interface) up

Method 2:-

Use Airmon-ng

Airmon-ng start [Interface] // To start monitor mode 
Note: Interface name changes from wlan0 to wlan0m
on which we you need to use in further steps.

Airmon-ng stop [interface]  // To stop monitor mode

Step 2:Use a tool called WASH to look for WPS

enabled routers 

Once you are in monitor mode. We will use 

a tool called wash to look for WPS enabled 

routers near us. Here is the command: wash I {interf

ace}. Note: This is the interface which is in monitor 

mode. If you used method 1, the name wouldn’t 

change but if you used method 2 (airmon-ng) the 

name of the interface would change for example: 

wlan0 to wlan0mon

So now we see a list of nearby routers which 
WPS enabled on the routers.

Step3: Attack the router using a tool

called REAVER

Now we attack this router using a tool called reaver 
which uses the brute force method to guess the WPS 
PIN. We carefully select one of the routers. In my 
case I used the first one. Note down the BSSID, 
channel number of that particular router because 
that would be utilized in the reaver command. 
So here is the command.

reaver -- bssid [BSSID of the particular 
router]channel [ Channel that router is working on] i 
[your wireless interface in monitor mode] -- 
vv [double verbosity to display non important 
output] As you can see in the screenshot above that 
the tool now starts trying different pins till it guesses 
the right pin.
