How Shady Ships are Spoofing Their Locations with Fake GPS Coordinates (nytimes.com) 92

Posted by EditorDavid from the shape-shifting-ships dept.
Slashdot reader artmancc writes: Like aircraft, many of the world's ocean-going vessels are required to have transponders that broadcast their location. The information is public and can be seen on websites such as AIS Marine Traffic. But according to an analysis reported in The New York Times , a maritime data company called Windward "has uncovered more than 500 cases of ships manipulating their satellite navigation systems to hide their locations."

The article, by Anatoly Kurmanaev, highlights the Cyprus-registered tanker Reliant, which was observed taking on oil at a Venezuelan refinery last December. At the same time, however, the ship was reporting its position as some 300 nautical miles (about 500 kilometers) away, "drifting innocuously off the coast of St. Lucia."
It's illegal (under international law), but the rapidly-growing practice lets ships circumvent international laws and sanctions, the Times reports, and "could transform how goods are moved around the world, with profound implications for the enforcement of international law, organized crime and global trade." Its use has included Chinese fishing fleets hiding operations in protected waters off South America, tankers concealing stops in Iranian oil ports, and container ships obfuscating journeys in the Middle East. A U.S. intelligence official, who discussed confidential government assessments on the condition of anonymity, said the deception tactic had already been used for weapons and drug smuggling. After originally discovering the deception near countries under sanction, Windward has since seen it spread as far as Australia and Antarctica.

"It's a new way for ships to transmit a completely different identity," said Matan Peled, a founder of Windward. "Things have unfolded at just an amazing and frightening speed...." The spread of AIS manipulation shows how easy it has become to subvert its underlying technology — the Global Positioning System, or GPS — which is used in everything from cellphones to power grids, said Dana Goward, a former senior U.S. Coast Guard official and the president of Resilient Navigation and Timing Foundation, a Virginia-based GPS policy group. "This shows just how vulnerable the system is," he said.

    Just to be clear, all of the "subvert technology" talk is sort of pointless. The AIS system is designed this way. AIS is using specific short wave frequency to send what amounts to clear text ASCII strings in packet form. These carry an individual ship identifier (MMSI number assigned globally) and a GPS position of the ship, as reported by the ship itself. The position is usually derived from a GPS receiver, but that is not a part of AIS system per-se, and it is both trivial and quite legal to provide the position in some other way (including entering it manually).

    Not only that, but as this is a clear text broadcast on radiowaves - there is nothing preventing a ship from entering another ship's identifier, or simply turning off its AIS transmitter. The system has no provisions for authentication or authorization and really cannot (at a minimum - it can always be turned off). While having an AIS transmitter is mandatory for large commercial vessels due to various laws, there are no technological means in the protocol to enforce that.

    In addition, some ships report position using a proprietary satellite tracking system. Again, there is nothing (other than the specific proprietary software interface) preventing the ship from keyeying in a position manually. This system is not considered mandatory (unlike the true AIS).

    The only way to track ships in a way that does not rely on their goodwill/cooperation is to use some form of an active tracking, where each ship must carry a non-powered identification device (antenna resonator?) and is surveyed externally (by satellite?). Even that could be somewhat circumvented (cover the antenna or cut it off and throw overboard) but the stakes are higher, and it's something that could be readily verified. I don't see that becoming the case anytime soon though.

        In the end, there's very little one can do. ADS-B can be enforced by various aviation organizations as it's required to be a part of air traffic control, but what they can do is limited. AIS is even more limited because only the coastal receives and coast guards can really enforce it, and there's a lot of water otherwise.

        In the end, it's really more about safety than anything - if you're misreporting your AIS and someone crashes into you, then maybe you have some explaining to do because everyone else's AIS will have records showing that. And there are plenty of things out there without AIS - swimmers, paddlers, canoers, kayakers, and other small vessels aren't required to equip AIS. (Of course, it also relies on the fact that the other vessel can probably avoid other ships easily, but you'll also probably want to not swim in busy shipping lanes).

        How many countries are ships registered in? If you exclude Panama, how many are left? So the answer is tie it to their insurance. Also, we're talking about commercal vessles, not Jeff Bezos yacht.

      So Class A transponders must have their own internal GPS receiver to operate as the SOTDMA transmission system requires the precise timing signal to work. The regulations that cover these transponders in turn require that the transmitted position be fed to a Class A transponder from the ship’s navigation system. The firmware on the transponder is supposed to sanity check that provided position against its internal receiver, and refuse to transmit if they’re more than x meters different (I think 300m).

      It’s pretty clear that these ships are running hacked transponders. However, it’s not hard to sanity check the data. The range of an AIS transmission is about 40 nautical miles at most. If you’re receiving a position that is more than that away from the receiver, you can pretty much consider it to be bogus.

      • Mod parent up- spoofing AIS in this way is obviously possible, but it at least for larger vessels it's not nearly as trivial as the OP makes it out to be. Maritime authorities also cross reference AIS data with radar and potentially other sources.

        At sea, yes. On land (for inland shipping) and maybe near the coast there are AIS base stations that can relay AIS messages. Still there is a limit on the amount of hops and it's still shouldn't be too hard to filter for obviously bogus positions.

      It's certainly a lot less convenient; but I'd imagine that, at least for the larger cargo and fishing vessels, optical satellite observations allow for some location inferences that would be pretty hard to avoid.

      Not 100% reliable, since you can't assume 24/7 coverage at sufficient resolution and and the correct wavelengths to deal with the weather in a given area; but between the ship itself and the wake they show up just fine when you do photograph an area; and they aren't blazingly fast so computing the potential movement during the times you don't have an eye on them is reasonably productive(and trivial, if you just draw a circle of the appropriate radius; more accurate if you've got information on currents and meteorological conditions).

      As with most inferential attacks, this also gets more powerful if you have other datasets to cross-reference it against: if a ship needs to stop lying on AIS, say, they run the risk of being either correlated with non-AIS detections of their earlier position via satellite or radar or of introducing a 'jump' in their position that cannot be reconciled with their actual maximum speed and/or the ships that weren't detected in a given area during the time they would have had to be travelling there for the route to work out. There's also observational data from ports and ships considered reliable(own and allied ports and coast guards, commercial observers in ports suspected of operating on a see-no-evil basis but not sufficiently hostile that such observers run a serious risk of getting shot for spying, own or friendly merchant ships given inducements for voluntary data sharing); and finally outright just sending someone to take a look if you care so much about it.

      Yes, more expensive than just taking an AIS dataset and having some Treasury GIS guys crunch up a report from the comfort of their office; but (except for very high value/very hot stuff that gets the disposable narco-sub treatment, is very carefully mixed with legitimate goods by competent smugglers, or which travels by diplomatic bag) the mere presence of bulk cargo ships and tankers, and the ports that serve them, is hard to hide; and there are few restrictions on RF or optical inspection of ships in international waters(or within national waters but from international waters). Something like the Venezuelan oil smuggling? Venezuela has a limited number of oil terminals(and apparently Jose Terminal accounts for the bulk of traffic), and those aren't something you build overnight or without being noticed; plus they all dump you into the Caribbean, which offers a handy mix of jurisdictions such that more or less anyone who isn't a total pariah state can find a friendly dock in the vicinity if they don't want to use a long-endurance blue water navy for the job of just keeping an eye on shipping. If the feds actually care there isn't an awful lot something with the radar signature of an oil tanker could do to avoid being observed going in and coming back out of one of the terminals and, approached closely enough to verify visual details and buoyancy changes consistent with having loaded or unloaded cargo. This will presumably get even harder to avoid as time goes on and drones with adequate range and good cameras become cheaper and more common, and partially autonomous operation of ships(to avoid the drag on endurance that having a crew eating food and getting bored causes) becomes more viable.

      Probably the bigger question is the 'and what are you going to do about it?' aspect. Even with today's rather haphazard enforcement you get periodic reports like this one(sometimes generalist, sometimes from specifically interested groups trying to protect fisheries or displeased at the flouting of a specific sanction); but unless getting caught is actually an expensive risk it doesn't really matter. There doesn't seem to be a lot of appetite for measures like cracking open the shell companies and going after the operators; or forbidding a ship caught flouting the rules from doing business in reputable ports from then on; or just plain boarding and seizing the thing. If there were, even a fairly leaky detection system would be a lot scarier.
