What is SAM?

SAM file stores all the user info and passwords of all the accounts of a computer using Windows NT family OS(Windows XP, Windows server 2003,etc.).So if you can somehow get this file you can get the passwords.

How can one find passwords from the SAM file?

There are three places where this file can be cracked from:-

i) From the original file
%systemroot%/system32/config
This file is locked to all users during the windows is running,so that you can't open it while you are working in windows. (Find out how you can use this file....Google dear frnds).

ii) The system keeps a backup of this file in the
%systemroot%/repair/sam._
This file is available to all users at any time. So copy this file to any directory and crack the passwords using any good password cracker. I would tell you about one, not only coz its very popular but also that its free.(Find others urselves the net has a gr8 many of them)

John the Ripper:- Its a dictionary cracker and will crack almost 80% of times you use it(unless the system admin has a knack in complicating things.)

iii) You can use PWDUMP to directly crack the passwords from the registry.pwdump uses .DLL injection in order to use the system account to view the password hashes stored in the registry.(Try to find out more about pwdump)

How to prevent people from cracking ur SAM file?

i) Try to avoid password which are dictionary words.

ii) Try to use special characters in ur password.

iii)Try to add non-printable ascii characters to your passwords

One More Method


NOTE: Please note, here, I am assuming that your Windows XP box has an administrator password.

First of all, get a Windows XP bootable CD, if you don’t have one , please read the section Hacking Techniques – Beginners.
Okay, after you get a Windows XP bootable CD, place it in your CD ROM or CD Re-Writer, now boot your computer through CD.

In Windows XP, during the splash screen, press F4 and then choose boot from CD.

Now, you will see a message on the screen saying that
“Press any key to boot from CD”

Once you get into the setup, you will observe that setup is inspecting your system and loading setup files. Once you get the Welcome to Setup screen, press ENTER to setup windows. The Licensing Agreement will be displayed next press F8 to agree it. The next screen will give you an option to do a repair. You will see that “If one of the following Windows XP installations is damaged, Setup can try to repair it”

Use UP and DOWN arrow keys to select Windows XP Installation and then press R to begin the Repair Process.

You must let the repair run. Setup will now check your disks and start copying installation files, this may take few minutes. After the Copying File process, you will be required to reboot.

NOTE: Reboot will happen automatically, you will see a red progress bar.

“Your Computer will reboot in 15 seconds”
During the reboot, do not press any key to continue because if you do then the normal boot up process will start.
Setup will automatically start and you will observe that Installing Windows is highlighted.

You have to keep your eye on the lower left side of the screen, when you see “Installing Devices”, press SHIFT+F10, this is the security hole in this operating system, you will now see a command console which will enable you to access your system.

Now, you have to type NUSRMGR.CPL and then press enter, to execute your command. Believe it or not, you will now gain a graphical access to your User Account in the Control Panel



Now, you can do anything, you can change the passwords of the accounts or you can even remove the passwords. After you have completed the manipulations, go to command prompt and type exit. Wait for the repair process to get over, then reboot your system and find the change.

You can also stop the password prompt, for this you must follow the same procedure given above. But, only one thing you have to change, in the command prompt type in control userpassword2, a screen will popup, choose log on without being asked for the password.

NOTE: After making changes in the command prompt or through the command prompt, always exit using the exit command, this will save the changes.
