Giga Wordlist Creator: automatic wordlist merging & optimization for wpa cracking

[M1ck3y]

Here is a little script I want to share with you. I called it "Giga Wordlist Creator", it merges and automatically optimize your wordlists for wpa cracking, I hope it can be useful for those who are interested in wpa cracking.

First thing to do is download Giga Wordlist Creator. Put it in /usr/bin, so you can use it from anywhere you're located in the shell, then right click on it, properties, permissions, is executable, yes.

Now you can open a shell and launch the script with:

wordlist.sh

Here is the menu, with the 4 steps that will make your personnal big wordlist for wpa cracking:



To be really efficient, you have to follow the steps in order. Here is a little explanation about how it works and what it makes:

--> 1 Merge all your wordlists files

Just give the script the path to a folder that contains a lot of wordlists files, and it will merge them all into a single big wordlist named Mega-dico.txt. This file will be created in a folder called Giga-wordlist that the script will create on the desktop of your Backtrack 3.

--> 2 Modify the dictionary with John The Ripper

Using JTR, the script will create about 50 differents variants of each password contained in your Mega-dico.txt file that you previously created on the step 1. It will output the result in /root/Desktop/Giga-wordlist/Mega-dico-john.txt, JTR makes variants this way, here is by example the result of the differents variants with the word "remote":

1remote
2remote
3remote
4remote
5remote
6remote
7remote
8remote
9remote
Etomer
REMOTE
Remote
Remote!
Remote.
Remote0
Remote1
Remote2
Remote3
Remote4

remote2
remote3
remote4

remote6
remote7
remote8
remote9
remote?
remoted
remoteetomer
remoteremote

So the chances to crack the passphrase are greater, as you got many variants that can be used.

--> 3 Optimize the dictionary for WPA cracking

The script will reduce your wordlist, removing passwords shorter than 8 characters and more than 63 characters, which is the min and max size of a WPA passphrase. Output file: /root/Desktop/Giga-wordlist/Mega-dico-wpa.txt

--> 4 Sort and remove duplicates

Finally, the script will remove duplicates, and sort the passwords in alphabetical order which, as i read I don't remember where, can make the crack a little more efficient. Output file: /root/Desktop/Giga-wordlist/Giga-wordlist.txt

You can easily edit the script and modify the paths and file names, if you prefer not to output the files on your desktop. After following the 4 steps, you will get your personnal optimized wordlist for wpa cracking.

I want to say thx to -=Xploit'z=- who gave us some useful commands that the script is using. I hope this little tool will help

Well done M1ck3y,
will give it a try when i've time and report back.
The script looks like a simple batch file but will make things easier.
Thx for sharing.
