In
my previous post here, I talked about how hard it is to trust the cyber space
in which our most valuable information passes through. Well today I wish to be
the devil’s advocate and show you how to crack a window based password
security. Don’t get me wrong but there are numerous situations which will
warrant the need to have the password cracked but if security is you hobby then
doing what we call professional hacking might be your excuse.
So
what do you need? Below is a list of the tool you will need.
2. A windows password file reset tool.
3. Another windows machine which you have
access to.
4. You attention might be a useful tool
too. J
Before
we start its important to note that in dual boot systems, usually the Linux
based system such as ubuntu can access a windows file system and that will be
the basis of our password cracking.
The
next thing to know is that windows passwords are stored in a file called SAM
which is found in the directory
C:\WINDOWS\SYSTEM32\CONFIG\
1. Shutdown down your machine.
2. Boot from the Ubuntu CD (or whatever
similar based Linux variant you have).
3. When its fully boots access the folder
in the path above then copy the file
named SAM.
4. Now go back to the other windows
machine and paste the SAM file wherever probably on the desktop.
5. Run the password file reset tool which
can be downloaded from here.
Note that there are multiple password
reset tool some which a free with other being proprietary.
From
the screenshot above, it’s clear what you need to do. Select the location of
the SAM file then click (RE) open.
It
will list all the user account available in the machine and then when you click
on an account the unlock or change password button will be activated. Play
around to fit your needs.
6. Exit from the tool and confirm that
the file has been edited by right clicking then going to properties.
7. Copy the file from where you got it
from.
We
are done and your password have been either changed or completely removed.
