Hacked Roadway signs warn of impending doom from Zombies

Zombies

An unidentified person reprogrammed two city construction road signs near the University of Texas Monday morning in an attempt to warn Austin Texas of an imminent zombie attack.
A hacker reprogrammed the 2 signs and changed the passwords. They had to wait until 8 a.m. to call the manufacturer's of the signs to figure out how to change the passwords and override the hacker's handiwork.

There have been no reports of Zombie's in the area.
