In high school I port-scanned the entire district network internally and sent direct prints to district HQ printers complaining about their lack of segmentation.

@SwiftOnSecurity My high school after-school job my senior year was coding at the school district's computer office. This was back in the days when "the network" was 300-baud modems.

I still recall accidentally erasing the existence of a junior high school one day. (Yes, we did daily backups.)
