Introduction: How to Get a Windows Password With Ophcrack
This is an instructable to teach you how to use the program Ophcrack to get windows passwords. I am sharing this to give people the knowledge how to do this. I do not take any responsibility for what you do with this information. I strongly advise you to not use this except on your own computer or to get permission prior to doing this.
Step 1: Getting the SAM File
In windows XP (which I will be using this whole instructable) the Sam files that we need are located in C: (if thats the hard drive with the OS on it) in C/windows/system32/config. If you cant find the sam files just hit ctrl+F and search for *.SAM and you will hopefully get the location. Now that you know where it is you need to get on a live CD of some sort. Because you cant copy the SAM file when Windows is active. I advise the Ophcrack Live CD because it has the ophcrack program on it already. A live flash drive could also be used. Save the whole Config file. I recommend saving it on a flash drive.
Step 2: Get Ophcrack
You could use the Ophcrack OS which is easy. I am using Ubuntu with Ophcrack installed on it. To get Ophcrack on Ubuntu just type in on the terminal "sudo apt-get install ophcrack" (with out quotes of corse) this will install the program. To open the program just type in "ophcrack" on a terminal.
Step 3: Tables
Now that you have the Sam files you need to open Ophcrack. If you don't have the tables you can get them at ophcrack.sourceforge.net/tables.php. You might be able to get the password cracked with out the tables but it is very unlikely. If you have a super fast computer or super slow internet the faster (not really but if you have a supercomputer with out INTERNET this might work) way might be using winrtgen (but this is super slow but does let you add special symbols).
Step 4: Cracking
Ok now just open the tables by going in to tables, then select the directory where you unzipped them. Now the pictures will show what to press from here.
