How to Crack a Windows Password February 6, 2011

Posted by Tournas Dimitrios in Uncategorized.

A couple posts ago I demonstrated how to bypass or even crack Linux passwords . Of course it was not my intention to gave  false sense that Linux is less secure than other operating systems . I must admit that my Windows skills are the absolute necessary , and not better than an average user . But at least I can break in a Windows box with the help of a Linux distribution 🙂 .

When many people hear that the login password for a Windows computer can be obtained by someone with little to no technical know-how they often don’t believe it. Well, the sad truth is that with the right tools the password can be obtained in under a minute assuming you can gain physical access to the computer. How you may ask, with a tool called Ophcrack. In fact, it’s so easy to do that it’s almost scary.

This is for educational purposes only. This blog is not at all responsible for how you use this information.

Ophcrack uses rainbow tables to quickly and efficiently crack the passwords on a Windows computer. The actual system is based on Slackware Linux. All you actually have to do is download the image file for Opcrack, burn it to a DVD, insert the disc into the computer and boot up from the disk, sit back and relax.

Opcrack quite literally does all of the work for you. How long does it take to crack a password? Well, it generally only takes around 10 seconds. Ophcrack can be a great tool for system admins who need to gain access to a machine that they don’t have the password too, but it can also be a weapon to gain access into a system that you’re not supposed to have access to.
