GPU password cracking made easy - Hack a Day

GPU password cracking made easy

The power that a Graphics Processing Unit presents can be harnessed to do some dirty work when trying to crack passwords. [Vijay] took a look at some of the options out there for cracking passwords and found that utilizing the GPU produces the correct password in a fraction of the time. On a Windows machine he pitted the Cain password recovery tool which uses the CPU for its calculations against ighashgpu which uses ATI or Nvidia graphics cards to do the deed. Hands down ighashgpu is the fastest; with Cain taking about one year to crack an eight character password while ighashgpu can do it in under nineteen hours.
We were very interested to see how easy it is to use this package. We looked in on GPU cracking in September but didn’t focus on the software packages that are out there. Now that you know how easily your password can be unearthed perhaps you will get some use out of this article discussing the usability and security of longer passwords which we ran across over on Reddit.

I wanted to try this out on some of the Computers in my Home Network. I have both an ATI and nVidia Video Cards, in two different Machines. But, sadly neither of them are supported. They are just a little too old, I guess. And I just bought my ATI a few months ago!:O I even looked in my Fedora Repo's and didn't find either of the Apps. I did find a nice little App when I searched for Cain though. It's called, fortune-firefly "Fortune-firefly provides a set of quotes from the popular television series "Firefly", and its movie "Serenity", by Joss Whedon. Quote authors include Tim Minear, Joss Whedon, Ben Edulund, Jane Esperson, Drew Z. Greenberg, Jose Molina, Cheryl Cain, and Brent Matthews." Cheryl Cain, being the reason it showed up in the search. Yep, I installed it, couldn't resist:) I've seen it before, but I'm not sure how to actually use it and see the great Wisdom of Firefly!;) Oh well... I have used several other Apps for finding or changing Forgotten Passwords in Windows Machines or Linux over the years. I usually use a Linux Boot CD, like System Rescue CD (since you need to do it offline anyway). There a quite a few Linux recovery CD-DVD's, that have the Password Recovery Apps on them. They are pretty fast and really all I need anyway. When I get an old Windows Machine given to me or a friend forgets their Password. That's all I really need an App like that for.... I have posted plenty about them on my Blog. You can use the Google Search Window on my Blog to fine the info. I searched for "recover password" and found allot... http://www.google.com/cse?cx=partner-pub-2221791110207294%3A3qlpn0jxpl8&ie=ISO-8859-1&q=recover+password&sa=Search&siteurl=donsdeals.blogspot.com%2F You can change it to something more specific to your needs and I bet you will find something good:)

My Video Card... The ATI Catalyst Control Center, says it's an ATI Radeon HD 4550 Card. And that is in the list of Supported Cards!:O
