Back when I was in high school, I decided it would be cool to try to hack into the school computer system. I grabbed the white pages, figured out the range of numbers belonging to the school, and fired up my demon dialer.

Sadly, the only system that picked up was an HVAC control computer with no authentication. Apparently they figured that no one would find the number. After some experimentation, I was able to change the temperature in specific buildings where I went to class, which was neat for about a day. Anyway, this article makes me wonder if that system is still online.
