Hackers Figured Out How to Hijack Shipping Vessel Tracking Systems

Illustration for article titled Hackers Figured Out How to Hijack Shipping Vessel Tracking Systems

A team of white hat hackers recently figured out how to break into the navigation technology used to track 400,000 shipping vessels worldwide. With this kind of access they could hypothetically make it appear as if a fleet of mystery ships was about to invade New York City. This is not good.

The affected system is known as the Automatic Identification System (AIS), and it's used by port authorities and shipping vessels alike to keep track of nearby craft. Because the systems evidently lacked security controls, researchers from cybersecurity firm Trend Micro were able to waltz right in and cause trouble using cheap radio equipment. They could make fake ships appear out of nowhere, real ships disappear inexplicably and create fake emergency alerts. In one case they made a real tugboat disappear from the Mississippi River and appear in a lake near Dallas.

Remember the series of horrifying cyber attack scenarios President Obama's suggested could cause real world damage? This is one of them. The fake fleet is one thing, but if the bad hackers decided to take advantage of this vulnerability, the limits of the damage they could cause would be bound only by their creativity. And this isn't even the only major security vulnerability that's been revealed this year. Over the summer, some students from the University of Texas figured out how to steer an $80 million yacht off course using fake GPS signals. Think of the fun the pirates would have with these hacks!

The good news is that the good guys got to this one first. The Trend Micro team just presented the findings of their research at the Hack in the Box conference, and hopefully the people behind AIS will at least add some encryption software to the system before Ghost Ship becomes more than just a B-movie.

DISCUSSION

AIS is pretty much just a position reporting system. It has a local range of under 30 miles, because it's based on VHF radio. There are websites where you can look at positions of over 50,000 vessels close enough to shore to get picked up. It's basically just a supplement to radar.

Hacking the devices wouldn't take much. It's a standard feature in most marine vhf radios. Typically the vessel gets a unique id, but that could be spoofed. Really, there isn't too much you could do with a fake one. Like you said, you could make a ghost fleet, but radar and visual will show it's not there. At best, it makes someone go to somewhere you want them to be, whether you want them to go somewhere you're not, or to come to you. But really, both of those things could be accomplished with normal radio chatter.
