Generating a phone number wordlist

I noticed that many people are so lazy to generate their own password for their wifi connection, that they just use their phone number as a password. Of course, this is hard to be found in a downloadable wordlist dictionary. So i present you the way to generate a wordlist phone number with the Backtrack utility: crunch.

First, move to this directory:

root@bt:~# cd /pentest/passwords/crunch  

 ./crunch 8 8 -t 20%%%%%% -o /root/Desktop/phonenumbers.txt  

- Notice that 8 8 means: start with 8 numbers and finish with all the possible combinations of 8 numbers

- You can change 8 by the number of digits that correspond to phone numbers in your country, like 10 10 etc

- 20 is the number of the phone provider i have chosen, you can replace this by the number of your convenience

- %=corresponds to the all the possible combinations from 0 to 9

- The number of %s must fit the number of characters of the phone number, for eg: if your phone number if 10 digits you must type % 10 times

- "-t" means to crunch that this a phone number and that he must not alter the phone number indicator, which is here (20)
