It's like a disease endemic to us nerds. Honestly who looks at the word "hack" and thinks hey i'm gonna make a white hat form of this? An OS called GNU?? Linus was lucky he had a buddy in marketing to help him name the kernel otherwise we'd have something like the clusterfuck in gnome & kde packages.
Decades ago to crack into a computer you needed to be a hacker, since computers were all different. Today we have "script kiddies" who most definitely aren't hackers, but are crackers.
I don't think there's a script-kiddie equivalent for phone systems.
Wierd, I thought war dialing (at least by hand) came about around the time of the Strowger Switch? I read somewhere (sorry, no link) that as telephones became popular people would ring numbers sequentially to see who was at the other end.
