Dude! What did that traffic sign say? Hackers change roadway messages

Drivers in downtown Sacramento, Calif., were treated for a couple hours last week to a flashing traffic alert unlike any they probably ever had seen.

There’s an electronic message board at 16th and P streets lately that has been warning drivers, “Left lane closed ahead.”

Except for one night last week when it announced: “—- yeah dude.” In all caps. Without those dashes.

Some people sent Sacramento Public Works Director Jerry Way a text and photo that night. He immediately called city dispatch: Get that thing turned off or turned around! Workers managed to pivot the board away from traffic. The next morning, the contractor for an apartment project on 16th Street got workers to change the message back.

It appears someone broke the lock and knew enough to hack into the computer and change the message, said Nann Reed, who is with Tricorp Hearn Construction, which is using a lane of the street for an apartment construction project. She said her company is asking the message board owners to “secure it in a way that this doesn’t happen again.”

So who’s the culprit?

Mat Almandariz, who’s with the company that owns the moveable message board, said it could be any number of people in the construction industry who are familiar with how the message board works and who possibly felt like impressing friends. It’s the first time one of his company’s boards has been hacked like that, he said. “It’s not easy to do.” For the full article click here
