While computer hackers have been known to hack bank and social media accounts, in a new twist a hacker has targeted electronic highway signs in North Carolina.
The Department of Transportation says five electronic signs that warn motorists of traffic hazards were hacked on Friday morning. The messages read "Hack by Sun Hacker"
The messages appeared on electronic billboards in the Asheville area as well as in Winston-Salem and Mount Airy. The messages were taken down after they were discovered.
DOT officials say they are investigating how the hacker was able to get into the private network used to put messages on the billboards.
