As you may have seen on the news or read on the internet, hacking sites have given people the instructions to hack into portable changeable message signs, like the one above. Although these hack sites give the stern warning, "***WARNING YOU SHOULD NEVER TAMPER WITH THESE SIGNS***", they then list the four-point instructions to do just that!HELPFUL HINT: If you deploy PCMSs, make sure you reset the password to something other than the default "DOTS". This may not stop the hackers, but at least it will slow them down for a while.
