With more and more people using Vista and Win7, I decided it was time to get my NT hash cracking on. So, I installed Windows 7 in a VM, setup up some lame test accounts:Username:PasswordTest:sevenlame:lamelamepass:lamepassyourmom:yourmom18j4:18j4I then ran it through Ophcrack. What came up?
Nothing but 'lame' and 'l8j4' and they were only found because Ophcrack bruteforces from 1-4 characters. I was quite surprised that the other passwords couldn't be found. I know Ophcrack exploits the weak LM hash used in XP and preceding, while the Vista Free tables are based on a dictionary and mutations, but I still figured that it would find all of those lame passwords. Yet, it didn't.I was just wondering, if any of you have cracked some NT hashes, be it from Vista or Windows 7, did you use Ophcrack?
What was the password? What tables did you use? And, how long did it take?If you use something other than Ophcrack (JTR, Cain, etc.), what do you use? What tables do you use and how large are they? On average, how long does it take you to crack an NT hash?

Rainbow tables are a waste of time and space when it comes to getting into a Windows box, unless you're trying to access encrypted files. If you have access to the machine, it's yours in less than 5 minutes.So how would one go about this?

Keep in mind that in my case these are customer machines. All too often the during the intake process the non-technical office manager forgets to ask for the password. We trying calling the customer first, but sometimes you get one that doesn't call back for days (vacation, whatever). It would be nice if I could get the PW as easy as removing it.
No-one really said why they were cracking Windows boxes, I was just thinking about removing the password, which is easy as pie. Gotta do what you gotta do, right? Besides, if you back up the SAM, you can set the password to nothing, do what you need to do, then put the old SAM back and the original password will be reinstated.blink blink.
