Austin (TX) - On January 19 during early morning traffic, a programmable road sign in Texas was hacked into. The perpetrators changed the message to read "Zombies Ahead". The sign is close to the University of Texas at Austin, near Lamar Boulevard and West 15th Street, and is likely just a college prank by a bunch of EE students.
Transportation officials are scrambling in an attempt to prevent this kind of hack from occurring in the future.
