Hackers hide funny messages in roadside signs; Homeland Security isn't laughing

Hackers hide funny messages in roadside signs; Homeland Security isn't laughing

When traffic is backed up on the freeway, or you see construction up ahead, your first instinct may be to grumble and put on the brakes. It could be a blown tire, a wreck, or the road is being torn up.

I bet you wouldn't think that it was a zombie attack or Godzilla! But that's exactly what's been happening with digital road signs across the country.

Who wouldn't laugh at the thought of a Godzilla attack in the middle of the United States? The new movie notwithstanding, there's a bigger threat with these signs than Godzilla.

These digital road signs, and the drivers that rely on them, have been victims of hacking. In some cases, the password for the digital road sign model has been posted online. In other cases, security is so abysmal that all it takes is one determined hacker to get into the system.

How can drivers rely on these road signs of they can be hacked so easily?

"Cybersecurity analyst Brian Krebs wrote on his blog that he thinks these types of hacks can have negative impacts, but are not in themselves malicious.

'We see a great deal of hand-waving and public discussion about the possibility that foreign cyber attackers may one day use vulnerabilities in our critical infrastructure to cause widespread problems in the United States. But my bet is that if this ever happens in a way that causes death and/or significant destruction, it will not be the result of a carefully-planned and executed cyber warfare manifesto, but rather the work of some moderately skilled and bored cracker who discovered that he could do it.'"

What do you think? Are these just harmless pranks or is there something more going on here? Tell me in the comments below!
