Password Cracker

[0gr3]

I'm trying to recover a user password for a customer of mine and I ran Ophcrack and it didn't detect the hash files so I was looking at using TRK (Trinity Repair Kit) or Rainbow crack. Have you guys used either and which would your recommend?

do you want to recover the password or just delete it, if you ready to delete it then use trk, but there are many others out there. google will help.

Can you boot into the admin account? On most off-the-shelf systems the admin account has no password.

If not, my preference is to boot into UBCD4Win (I forget which app) and create a new admin account and then reboot into the new account and change the passwords.

I have one on a CD, but cannot remember the damn name of it. I know I got it for free after doing some Google searching.

Anyway its a live CD that allows you to reset the password for any account along with some other fun stuff. The CD is at the shop, but when I get there in the morning I will post the name of it.

OphCrack if I need the password in case there are encrypted files. If I can delete it, I just boot using the Ultimate Boot CD.

If you want to get to the windows desktop and then renew the password you might want to try kon-boot. When you boot from the cd it will bypass the required log in screen and go straight to the desktop. I have not used it on any customer machines, but i did use it on my test machine without any problems.

Make sure that you're using the correct Ophcrack, there are two versions one for XP and one for Vista. If that doesn't work you can try to download and add some of the extended tables off of their website.

I haven't used other tools because Ophcrack has worked so well for me in the past but I'm always happy to learn about new tools to add so please share.

When you used Ophcrack did you shutdown windows properly first or just power off the machine?

I rebooted and ran the live disk. Start>dumb vista icon>reboot.
Edit - I can only access a limited profile hence the issue. He needs access to his Admin account.

I use the exact same CD. The CD that cannot be named!

Active Password Changer works very well. Google for "Active Password Changer 3.0.420" if you want to get the latest version.

Thx all! If you get that CD name ProTech wanna PM me?

does that work with vista?

Well first make sure it does not violate any laws in your area, some areas it is against the law, no matter if you have the customers permission.

But you can use a live cd called pc login now from pcloginnow.com
its a easy to use live cd. other then that you can use nt offline password & registry editor from

home.eunet.no/pnordahl/ntpasswd/

hope this helps, but remeber resetting a password this way is a bad ideal if the user has enabled EFS on the system.

Once you reset the password, they will loose all data.

 

[Skyhooker]

I use both Ophcrack and PC Login Now - one of those should work.

Fastest, easiest, and best I have ever seen is Active @ Boot Disk, nothing else looks or works nearly as well. Tried most if not all the above mentioned by the way.

for xp install cd

from a bootable linux cd (backtrack4 example)

if you can retrieve the hash you can submit it to some online cracking service like http://www.plain-text.info/
if you are comfortable with using IRC i would suggest using their irc channel to submit it , its faster than waiting for the web cracker

I second the use the Lsoft Active boot disk for password recovery.

Sweet, glad you like it Nick, certainly looks really nice too, and I see gazza joins the club. Gotta love how fast and easy it is and that all accounts can be done so fast, leaves them blank when done too, all around the best!
