Hackers took advantage of an Austin, Texas, sign to change it to ‘Zombie’ message. The sign was returned to its original message within hours of the pranksters’ attempt. The pranksters had to physically break into the sign to get it back to the original message. Hackers are looking closely at the nearby University of Texas to see if the prankster had planned their attack there. The university insists that the sign was equipped with external locks, and that the hackers had to break in to change the message.”]
