Ok I'm feeling motivated once again so here's more tutorials. Feeling quite annoyed that there's no general tutorial section so I'll just put it in here.
I. Needed tools:
1. Any linux live distro
--Knoppix : KNOPPIX - Mirrors
--Ubuntu : Download Ubuntu | Ubuntu
2. LM Extractor + Cracker
Cain : oxid.it - Cain & Abel
Pwdump2 : http://www.openwall.com/passwords/dl/pwdump/pwdump2.zip
3. Data Transportation
Any of the following will do:
iPod : Yes, an iPod
USB Drive : Flash drive, memory stick, etc...
Floppy : You will need 2; due to the file size
II. Method:
1. First off try to bring your iPod or flash drive to class daily
at least a week before you actually attempt this, so nothing seems
out of the ordinary.
2. Alright, so here is the last day of the week, your bored, but you need admin on the school computers to install Steam and play CS. First off, choose a computer
where the screen isn't facing the teacher. Once you get to it, immediately pop the linux cd into the drive, and hold the power button down for 10seconds to do a force-shutdown.
3. When the live cd boots up login to linux and pull up a terminal.
4. Once in the terminal, plugin your iPod or USB drive (floppies, if
you use them will come later.)
5. Now, you will have to check 'fstab' and look for where your iPod or USB drive is and mount it. Make sure when you mount it, that you mount it with 'write' permissions otherwise you would get all kinds of errors.
6. Once it is mounted go into 'C:\windows\system32\config' and copy
the 'SAM' and 'SYSTEM' files onto your storage device. This is also the step
where if you are using floppies to put floppy in for each. WARNING:
depending on amount of users and other factors it may not fit on a
floppy drive.
7. Once saved, pull out the iPod and/or USB drive. Also don't
forget the LIVE cd you used. Then do another force-shutdown
III. Cracking:
1. By now I would've hoped you downloaded one of the LM hash crackers outlined above.
2. Using Cain & Abel from oxid.it, open it, click on 'Cracker'
select 'lm' and import the unnecessary files.
3. Have it start, once it has begun set your processor priority a notch
above what it is. DO NOT SET IT TO 'real-time' or 'high.'
4. Depending on the complexity of the password/hash it should be around
8-10 hours of cracking. My schools was something like '34gdfgDf4g5' and
I was finished within a nights rest.
IV. Getting in safely:
Chances are your school runs on windows xp and is using domain-login.
This is the most common way to monitor, and update a windows network as
large as a public school. So now that you have username/password of the
admin account for one computer in your lab there is a 95% chance it is the
same for all those other accounts. Unfortunately you come into one big problem
here.
### ALL ADMIN ACCOUNT LOGONS ON A DOMAIN ARE LOGGED. ###
Put simply, if you mess this part up, enjoy suspension/jail.
Walk up to the computer, getting to class early obviously, and unplug the
ethernet cord from the back of the computer. THIS IS ESSENTIAL FOR YOUR
SAFETY.
Now log on to the computer using your admin account. Quickly go in and add
another admin user, using the control panel 'Manage Users.'
TIP: Make sure the name/pass you create for a new admin, is totally random
thus leaving no 'bread crumb trails.'
Logout, then plug in the ethernet cord, and log in to your new admin account.
Cheers!
FootNotes:
To take this one step further, when you get to your Windows 2000/XP log on
screen look at the domain that you log into.
Resolve the host name and get the ip. Even without IP you can use remote desktop
client that comes on all the machines by default. Even if it is not in the menu
because your computer admin thinks he is smart open up 'run' or the address bar on top
of 'My Documents' and type 'mstsc.'
Once opened type in domain name and hit connect. If you see another login window you can
try the admin password you used.

So be careful, use a proxy, etc.
