A wordlist is text file that contain all the key combinations of all the possible passwords.Wordlists are used for breaking pincodes,passwords and even phone numbers.There are some inbuilt worldlists available in kali Linux.Want to check type this command. ls /usr/share/wordlists
Disclaimer – Our tutorials are designed to aid aspiring pen testers/security enthusiasts in learning new skills, we only recommend that you test this tutorial on a system that belongs to YOU. We do not accept responsibility for anyone who thinks it’s a good idea to try to use this to attempt to hack systems that do not belong to you
But in this article we will create our own custom wordlists with a program called crunch. Crunch comes pre-installed in Kali Linux. Crunh is very stable and works flawlessly.
Open your terminal and type the following command.It tells a little about crunch.
General syntax to use crunch is :
- You have to specify minimum and maximum number of words.
- You have to specify the specific pattern.It depends on you how you want it to be.
Let’s do it practically with real world examples. So fire up your terminal.And type the following command.
Create Wordlist
In the above example we specified 5 minimum and 5 maximum numbers in our first argument.So our minimum and maximum numbers are going to be 5.
Second argument numbers from 0 to 9 means crunch will use numbers from 0 to 9 to generate all the possible combinations 5 numbers
Once you hit enter you will see it starts generating combinations.So by checking output you will understand it better.
Save wordlist to a file
We must supply -o argument with path where you want to save wordlist.
The -o option is for writing wordlist to a file but you must provide right path.When you execute the above command your file will be saved in desktop.
Create wordlist of lowercase characters
Now below command will generate all the possible combinations of 7 characters
File will contain all the possible combinations of 7 characters. This is actually useful let’s say if your router’s password length is 7 characters and only uses characters then password can be found in the list.It will generate a massive file though.
