Malaysian construction companies are not really in the habit of using these electrical sign boards to warn motorists of danger but you do encounter one once in a while. Now what would you do if you came across one that said “Zombies Ahead”. Well, that’s exactly what one MIT student did when he got his hands on a unprotected electronic signboard. Apparently, these sign boards are not well protected by any substantial security measures and changing a sign only requires the ability to type. I’m not saying we should all go hacking electrical road signs but out of curiosity, what would you type in?
