BALTIMORE (AP) Electronic road signs in Maryland haven’t been immune to the unusual messages that have been appearing on signs in at least three other states.
Kelly Melhem of the Maryland Transportation Authority said a portable sign was hacked recently on Route 43, White Marsh Boulevard. Melhem said one message mentioned zombies and another said “I love Tony.’’
Warnings about zombies also were included in electronic signs changed in recent days by hackers in Illinois and Texas. A sign in Indiana warned motorists of “raptors ahead.’’
Melhem said the hacked sign has been removed, and security is being increased to prevent more hacking.
