My messing around in high school was comparably minor. Our network ran Novell NetWare and I managed to discover that there was an unsecured Website that had a number of interest. Most of them were read-only with pretty boring info. However, there was also a messaging function that allowed you to send messages to any machine on the network that would appear as a popup. A couple friends and I messed around a little and I promptly forgot about it.<p>Turns out someone else had found out about this and decided to make use of the much more dangerous broadcast functionality. I can&#x27;t remember the message that was sent, but I believe it involved some profanities against our principal. Of course they didn&#x27;t think such a message could be tracked but it was. I think this person was only suspended for a few days, but the admin learned his lesson and secured things after that.
