You’ve seen those electronic roadside signs, of course. They’re used to warn of changing traffic conditions or upcoming hazards.
In Arizona last week, near Tucson, one of these signs was hacked, with the message changed to warn drivers on the highway that there were zombies ahead on the roadway.
Although obviously adept at programming these devices, the hackers could have made use of a spell checker, as they programmed the sign to read “Caaution Zombies ahead!”.
