I am back with another dark tip. This time I am going to talk about how to crack Windows Passwords and will teach you the most simple way to prevent the crack from happening to you.
So firstly we need to get ourselves some Rainbow Tables. A Rainbow Table is a pre-computed set of LM hashes. LM is short for Lan Manager and that hash is what stores your Windows password because it would be “suicide” to keep windows passwords in plain simple text. A LM hash can range from 300 MB’s to 40 GB’s. You can crack most windows passwords with just about 1 GB’s worth of a Rainbow Table.
Once you have the table you could get rcrack but if you find that Command Prompt is just a pain to handle then you probably would not want to use it. So what you can do is get a program called Cain & Abel and that will store the Rainbow Table hashes in its interface when you tell it to crack. You should click the cracker tab and then the + button and for this example just tell it to pick up your local system. Now right the click the account you want to crack and select dictionary attack then LM Hashes. Now add your Rainbow tables and simply select start. Once it has finished off and if it does tell you your password then you need to secure that. There is a link included on how to stop LM hashes.
