So in this tutorial we will create our own word-list by using the tool called "crunch" in backtrack.
Crunch is a tool used for creating password list & also it can be used to compress the output file in various formats.
So now...what??
Let's start....
Fire up your BACKTRACK machine ,goto bash & type:-
cd /pentest/exploits/password/crunch
If not there you can download it from
www.sourceforge.net/projects/crunch-wordlist/
to install it..hit the under below commands:-
1. tar -zxf crunch-3.2.tgz (3.2 is the version of crunch,it might be changed if updated)
2./crunch-3.2
3.make install
Now if it get installed successfully ,then type the commands in the bash to generate the list:-
cd /pentest/exploits/password/crunch
First let's see the syntax of crunch:-
./crunch [min.Length] [max. Length] [character set] -o /root/Desktop/wordlist.txt
It will create a file on Desktop by name wordlist.txt .In example below we will see basic usage of crunch:-
./crunch 1 2 1234567890 - o /root/Desktop/wordlist.txt
it will create a word-list of min. 1 & max 2 number digit & save the output file on Desktop
Now we will be creating the password list of mobile numbers which starts with "9" .ex 9838222454(its not my gf number)
here we go:-
crunch # ./crunch 10 10 -f charset.lst numeric -t 9%%%%%%%%% -o wordlist.txt
It will create all the numbers starting with "9"(you might know that min & max digit of mobile is 10 without country-code).
You can also add special symbols too & explore it to know how to compress the output file we are getting.
