Saying “sup” with `net send`
This brings back good memories from High School. Here's a bunch of things we used to do:<p>1. Set fun messages on all the HP Printers: <a href="https://www.irongeek.com/i.php?page=security/jetdirecthack" rel="nofollow">https://www.irongeek.com/i.php?page=security/jetdirecthack</a><p>2. Bypass firewall restrictions by setting <a href="http://" rel="nofollow">http://</a> to <a href="https://" rel="nofollow">https://</a> (later had to resort to SSH tunneling using Putty). Got me banned from our library for a month when I was on Facebook and a teacher passed by.<p>3. Our student directory set a cookie to a 6 digit identifier in the cookie. We could access any student's grades and details by just setting it to another ID, or looking at their lunch card.<p>4. During finals we wouldn't be allowed to see our grades until after all the finals were submitted into our grading portal. Somebody picked up on the fact that if you stop the page load before it finished that the grades would show up. Using JS to block our grades after they loaded didn't stop even the least technical people.<p>5. Some of our labs had monitoring software to make sure we were working. We could just kill that process and they would lose access.<p>6. Invert MacOS screen colors using Control + Option + Command + 8. Teachers didn't know how to recover from this and would resort to restoring the entire Mac.<p>7. CTRL + ALT + Down to flip the Windows screens. Again caused issues for a lot of people who didn't know this shortcut.<p>What a bunch of troublemakers we were...
