So as we agree on the previous lecture that using some common word lists like dark code lists or any
other road list is good but it's taking long time and you know it it may be not that effective if consider
a few create your own work list.
So let's create our own world list.
So for example assume that I think that my victim may be using his mobile number as worthless.
And actually this is very common at least from wireless.
A lot of people are using their cell number or mobile number as their password.
So I need to create a password that I'm sorry I need to create order lists that got all the mobile number
right.
And I'm assuming that I don't know his mobile number so I'm going to create a list that includes all
mobile number I'm going to try.
This could be effective.
What about if I know some information about my victim I know their family member names her date of birth.
I can create a file that has a different kind of combination including the name and the password.
And I'm sorry the name and the date of birth and.
And think about it.
What is your own password.
Most probably it would be in this area.
You are using some of your family members.
Some date of birth maybe specific dates.
So if I was able to collect some information I can create the files it has a different kind of combination
and I can end up getting your password.
So let's see how to create a work list at the beginning and then let's see how to create a very effective
workplace.
So the tools that we use is called Crunch.
It's a very effective tool.
So if I create if I type here for instance crunch
and after typing crunch I putting the
minimum password and maximum possible for the system say I need the files that include all the password
from five two from two to five and I'm going to type minus three which I'm sorry minus all which will
be the output of the file and I'm gonna save it in my location in route under the name of uh.
Or this one note G.
Now EU he will choose that this file will be 70 megabyte and it will include this amount of puzzle.
Why.
Because he gonna put all the combination letters a number and especial character and and uh smaller
letter and so on.
And I can check the file just typed nano W and one note 60 and
it's taking time because it's considered a big time a big file for a text file its readings are fine
and you're going to see in a few seconds that it would show you all the password inside just instead
of doing that because this will take time.
Let me try.
Two cats a fine cat w n zero one the next year AWOL one I'm sorry
to excite you too as you can see.
See it's a big file has different combination from three to five letter.
No special character but this is not the effective ways that I was talking about the effective way would
be for instance.
I need to specify the audience.
I don't need random numbers and letters.
So for instance assumes that from my country all the mobile number are four digit the is anything but
just for simplicity and they start with 0 1.
Right.
So I need to create a world list that include all mobile number or cell number that start with 0 1 and
whatever other number is there and it should not include any letters because no mobile number gets letters.
So I can customize the crunch comments so I can type it this way crunch since I know that all the mobile
number is 4 for instance.
So I'm gonna tell him.
Just put four character minimum four and maximum four and then I'm content and I'm gonna tell him.
Just put the number zero one two three four five six seven eight nine.
So by doing that I'm turning only use number in this file.
Then I'm gonna use minus T minus C to specifies a format I'm certain to start all the puzzle with zero
one and whatever to correct the remaining I'm going to put those at sine mean just keep the change on
the third and fourth while it's the first and second just keep them 0 on 1.
Of course if you need to do a real file you gonna put instead of 4 10 and you can start to real mobile
number codes that you are using in your country and let's see.
So it shouldn't take time because this is a small file.
It only have 10 password and then I can try to check it.
Let's see uh get everyone.
And as you can see he gave me all the number with all every all the possible that could start to zero
one and whatever number after that.
So this is a way for doing a customer balance.
Now let's take a more advanced way and more effective way as when.
