Fern WIFI cracker
Disclaimer: I carried out this attack using my own WIFI network, all MAC Addresses and names have been faked. This tutorial is for learning purposes only and should not be used for any illegal activities.
This is a step by step on how to use the Fern WIFI Cracker that comes installed with Kali-Linux. I used a Surface Pro to share a WPA2 network (which is a pain to do when you realise that windows 8 has taken out the GUI ability to create a adhoc network!!! you now have to use command to do it.) I connected to the network with another device for reasons that will come apparent later in the tutorial, then I cracked it This is by far one of the most user friendly tools I have used and is great for beginners.
Step 1 - Setting up your wifi adaptor to monitor mode
Open a terminal window and type:
Step 2 - Launch Fern WIFI Cracker
Once launched click on the select interface as seen below:
Now if your wireless card successfully entered monitor mode from the first step you should see the following:
Step 3 - Detecting a network to crack
Click the top button highlighted below to activate the search, your results will be displayed as WEP or WPA networks as seen below, you then click on the relevent button ie WPA:
Step 4 - Select a network to crack
Click on your chosen network then ensure that you click regular attack, browse to your dictionary file select it and then wait for the program to find a client to deauth.
The program has a worldlist (file path seen below) but its not great you will want to have your own to crack networks with strong passwords.
Step 5 - Attack the network
Once selecting a wordlist file (highlighted below as common.txt) and a client MAC to deauth you can run your attack:
As you can see below the wordlist common.txt did not contain my password so you will need to either use a different wordlist or update this one.
To save time i updated the wordlist with the password of the network and as you can see below it cracked it
Fern WIFI Cracker contains a key database were it saves keys from networks that have been previously hacked.
This is the key from the HackMe network that we just hacked
I've found this a very easy and self explanatory tool to use, its great for beginners and cracks not just WPA but WEP and WPS with ease. The only points to note are that based on the password of the network and the length of your wordlist it may take quite some time to crack.
