It has been done by hackers before-- a couple of years ago in Montana. It seems that a lot of radio and TV stations had their EAS gear on the internet-- with the default password. Doh.
But I doubt it's a hacker in this case, since it was nationwide. I think somebody fumble-fingered something, and is now looking for another job.
soooo, anyone know of a media position with a TV or Radio company?
