Texas transportation officials are baffled by a recent science fiction inspired vandal, who was apparently able to hack into a mobile road-sign. Lippincott, a passerby, described the message as "sort of amusing, but not at all helpful".
What amused Lippincott the most was not the hacking of the sign itself, but instead it was the message he had read. The $15,000 sign was left with the message, "Zombies Ahead", for several hours before officials could summon a crew to fix the sign.
According to i-hacked.com, it is not uncommon for these road signs to be left with unlocked external panels, and default firmware passwords. i-hacked stated that, "Programming is as simple as scrolling down the menu selection". No zombies were seen.
