Are you surprised? Of course not. What's there to be surprised about? You post an article about how to hack something, and people try it. Simple as that.
(Traffic Controller Bruce) Jones, who has one of only two keys to the locked access panels on the portable signs, said that the hacker broke into the panels [arguable] on each sign and bypassed the passwords before leaving five different zombie messages and even changing one of the passwords. Jones said he had to wait until 8 a.m. to call the manufacturing company to figure out how to override the hacker's work [Bruce, please see original article]. He speculated that the hacker could be a computer genius from UT.
A computer genius from UT! Or, I dunno, somebody who read an article on the internet. Whatever the case, the zombie thing was cute in the beginning folks, but it's time to start thinking outside the brain. The robots are coming too, you know.
Hit the jump for the other five messages left on the signs and the link to a video news report.
Thanks to Ghostface, Derrick, Brian, Nick, sarah, Jordan and Andrea, who can program road signs with their minds because they were all struck by lightning while carpooling in the HOV lane.
