WILMINGTON, NC (WWAY) -- The North Carolina Department of Transportation says the FBI is looking into a group that hacked into at least five digital road signs yesterday, including one in New Hanover County.
The DOT says it is also evaluation the security measures in place for its digital road signs after a group changed the intended transportation-related messages on the signs to an advertisement for its Twitter account. According to a news released, the DOT corrected the messages as soon as it discovered the hackings.
The DOT says the hacked message boards are on Carolina Beach Road in New Hanover county, I-40 and I-240 in Asheville, US 421 in Winston-Salem and I-77 near the North Carolina/Virginia state line.
"We're taking this cyber event very seriously," NCDOT Chief Information Officer David Ulmer said in the release. "We're not only working with the authorities to investigate this serious incident, but we're also doing multiple security scans on our equipment and our IT infrastructure to make sure we close any further vulnerabilities."
The DOT says it has identified how the hackers got into its system, and now has crews across the state physically inspecting each sign to ensure its settings do not leave it exposed to hackers. That work was expected to be done by this morning.
The agency's IT information security team is also scanning the internet-related connections to the signs to confirm there are no further vulnerabilities in this area. That process should wrap up later this weekend.
Signs in Wyoming were also reportedly hacked by the same group.
