Password Cracker
I want to crack a mac o/s password. I've had the computer for a while and after I moved I had it in storage. I've forgotten my password beause its been so long. But I don't just want to reinstall the o/c because of some information that i have on there (i,e. pictures and some documents). If there is anyone that could help me with this if you could get back to me that would be great thank you!

Otherwise, no, there's really no way.
Plus I want to just figure out the password. I don't want to change it!
Well that's certainly .. er, interesting. I can only think of one reason that someone wouldn't want to change a password.

That said, if one holds down the "s" key at start up, Macs boot into a mode where you have root privileges, allowing you to do what you want to the machine.
If you combine these two together, you can actually create a boot process that recovers lost passwords. JTR has the ability to pick up cracking where it left off.
Handy tip: grab the password hash, and use multiple machines to recover the password. One starts recovering 6-character passwords, another 7, and another, 8. If you were secure when you made your (now forgotten) password, it will be 8 characters long.
Hope this helps. Google for the rest.
Is there a way around this? The computer is running windows 2000 Pro.
Follow the advice given in this thread and change the password. Shut down the computer when you're done. If your boyfriend is cheating on you, confront him with the evidence, dump him, and move on. If you don't find any evidence and he gets suspicious because he can't log in anymore tell him you accidentally pulled the power cord on the computer while you were cleaning and it must have corrupted the hard drive. Then tell him how to boot into single user mode and change the password.
There is one other option: Call me an asshole for making baseless assumptions about you and your motives. Bonus points if you post a pic of yourself, instantly causing every male on the board to take your side get me banned.
Wild guess here... feel free to ignore:

I think you hit the nail on the head, elron.
strangely enough, the stupid cow in our front office has forgotten her username and password and no-one in the complay knows the administrator password either. I've been hacking around all morning trying to get in, but I cant do it.

Never had to use it (luckily) but researched it as a backup plan from here:

If you use it, let me know how it works!
When I "forget" passwords on Macs running OS X, I tend to google John The Ripper, wink wink. It even plows through data at 128-bit chunks on Altivec-enabled computers (eg: G4, G5).

Ummmm - ok, I now have this idea that I want to reasess the passwords I'm using on my machines ... my current passwords are 8 character alphanumeric - how long would that take a computer to break?

It depends how someone goes about cracking it. There really is no definite time it takes because for one thing, if you picked a common word or a mixture, then a dictionary attack combined with numerals could get access in possibly a few minutes or hours.
If it's really obscure then it could take weeks. But then again, who says they have to guess your password? If they install a keylogger, then they'll get your password pretty easily. You can hack into the most secure agencies in the world that way.

Keychain Access has a password-strength utility when you use the Change Password menu item. It tells you as you type it in how strong it is.

for now, i have given her a new computer and set it up so that i know all the passwords, - now I have over break to take the hard-drive out and plug it in to my computer and see if I can get access to any of the files she needs before wiping it clean and starting afresh.
I think she did it all of her own accord to get a new computer, it turns out she changed her password over 3 months ago, and has been logging in with it every day, until one day she forgot it. Yeah right...
atleast now, she doesn't have the priviliges to screw her pc up anymore.

*Raises hand* Uh, I actually mad a dumb move about 3 years ago and backed up my laptop to a encrypted disk image. The drive was acting up and died a few weeks later. To this day, I have a 20GB disk image and no passwords ever work. It is not enough to just crack the password anymore, I don't need the data, but I want to know WHAT THE HECK I WROTE IN THE FIRST PLACE!
