The system owners can&amp;#x27;t know that to be true and have to proceed as if the systems are compromised.

Rather than booting into Ophcrack I&amp;#x27;d just log in with the admin account and run pwdump from a USB stick to collect password hashes. I figured out how to enumerate Windows machines over the network using NetBIOS and ran the pwdump utility remotely using psexec, so that I could hit every computer in the library at once, or every computer in a computer lab, etc.&lt;p&gt;I ended up cracking credentials for most students and faculty on the entire campus.

It was purely a hack for the thrill of breaking down barriers and outsmarting the security. But MONTHS later after I had long since grown tired of tinkering with this stuff, a couple of uniformed police officers pulled me out of Calculus class and took me downtown. They tossed my dorm room and confiscated my computer and my phone and every piece of digital storage I owned. The school threw the book at me, I guess because they were so embarrassed by their incompetence on display from being beaten by a 16 year old.&lt;p&gt;(Posting on my alt account for obvious reasons.)</text></item><item><author>whalesalad</author><text>I remember cracking the password from a Windows system in high school.

I think I used lophtcrack? The head admin account for the entire school district (basically root) had the password “north”. It took like a fraction of a second to crack.
