Insurance Company Dongles Don't Offer Much Assurance Against Hacking 199

Posted by timothy from the best-hanging-from-rearview-mirror dept.
According to a story at Forbes, Digital Bond Labs hacker Corey Thuen has some news that should make you think twice about saving a few bucks on insurance by adding a company-supplied car-tracking OBD2 dongle: It’s long been theorised that [Progressive Insurance's Snapshot and other] such usage-based insurance dongles, which are permeating the market apace, would be a viable attack vector. Thuen says he’s now proven those hypotheses; previous attacks via dongles either didn’t name the OBD2 devices or focused on another kind of technology, namely Zubie, which tracks the performance of vehicles for maintenance and safety purposes. ... He started by extracting the firmware from the dongle, reverse engineering it and determining how to exploit it. It emerged the Snapshot technology, manufactured by Xirgo Technologies, was completely lacking in the security department, Thuen said. “The firmware running on the dongle is minimal and insecure. It does no validation or signing of firmware updates, no secure boot, no cellular authentication, no secure communications or encryption, no data execution prevention or attack mitigation technologies basically it uses no security technologies whatsoever.”

    I've long thought there could be a really lucrative market for OBD2 spoofers. Instead of plugging the dongle directly into your car, plug it into a middle-man that feeds it the "happiest" possible data to make it think your driving is perfect. There is no authentication in the OBD2 protocol so there is no way for the dongle to tell the difference between a real OBD2 data feed and a spoofed one.

    The most obvious reason for an attack here is to commit insurance fraud. At present, an insurance company is forced to base an insurance premium on all the meta-data they can possibly gather about the prospective client, excepting their sex if they are in the EU (although this may well lead to a quite astonishing number of men called "Sue", if insurance companies attempt to bypass this and link first names to insurance risk).

    A data-gathering dongle would seem to offer a much better deal, allowing the company to charge more if the user indulges in risky behaviour of some description.

    A possible reason for hacking into the module would therefore be to falsify the data sent back to the company; a boy racer who regularly breaks speed limits, corners absurdly fast and brakes late if at all would gain substantially from a fraudulent data recording which portrayed him as someone with the driving habits of an octogenarian grandmother; such a person might also think that the gamble of sending such phoney data was well worth the savings when set against the fairly low risk of getting caught.

    It therefore worries me that companies are this lazy when building such equipment. It really doesn't take all that much to keep out the majority of crackers right from the start, and as the skilled ones are in the minority, taking a little care initially would pay dividends down the line.

Presuming there are timestamps on the accelerations, they can model traffic flows.

        Just as a point of interest, there was a talk at Defcon last year where someone built a IPS (intrusion prevention system) for the bus of the car. It turns out that the communication matrix for a car is a very static system. The parts of a car that communicate with each other do so often (e.g. Engine controller and injection system), and predictably. Other parts that don't (e.g. entertainment system, or that ODBII plug from the insurance company and the traction control system) never do. So it's possible to build a device that models the system by listening on the bus and if it suddenly sees new traffic patterns shorts out the bus, leaving you with a less smart, but still on 4 wheels and not careening into oncoming traffic, car.

          No need to do such extreme damage, when the same effect can be achieved with a simple fuse on the positive voltage line of the port. Suspicious activity? Burn the fuse-- BAM-- port is dead, but easily fixed.

          However, this would require a "smart" component inside the dash, between the actual ignition control system/ACS system, and the ODBII port interface. Such a device would need to have a reference pattern to check current communications against, and would need some level of processing capacity to compare realtime engine diagnostic data and bus activity against the reference. (Does not need to be fancy here, but this does imply the ability to program a new reference pattern later, especially if the system is fully adaptive to changing engine conditions over time.)

          This then places some significant implementation considerations on the vehicle manufacturer-- this device has to somehow be able to be field-reset at a dealership if it gets confused after having the engine serviced, and also needs to have nothing but read-only access to the engine's control system. The only thing it should have "write" access to should be the fuse. (And maybe an indicator lamp)

          However, given the less than spectacular implementations of integrated devices in modern vehicles (in terms of security, and security oriented design/implementation) I question if such a device would be properly implemented.

          I get the sneaky suspicion that the automaker would be ... "tempted" ... by dealerships and other retailers in the market to integrate lojack functionalty into the security device, thus making it itself into the target of exploits. (Otherwise, the purposeful activation of the intrusion failsafe would render actual lojacks incapable of stopping cars, by disabling the communication bus. This means removing the fuse would essentially disable such countermeasures.) This would then make "remove the dongle" no longer an option.

          When presented with a choice between "properly implemented security" and "Pressure from their customers" (Auto manufacturers RARELY, if ever, sell directly to the public. THEIR customers are the dealerships.) , I expect automakers will choose to placate their customers every single time.

    From the article.

    By hooking up his laptop directly to the device he says he would have been able to unlock doors, start the car and gather engine information, but he chose not to “weaponise” his exploits

    SO only direct connect has been proven.

    The researcher noted that for a remote attack to take place, the concomitant u-blox modem, which handles the connection between Progressive’s servers and the dongle, would have to be compromised too. Such systems have been exploited in the past, as noted in a paper here from Ralf-Philipp Weinmann, from the University of Luxembourg.

    Remote access has only been shown by similar systems.

    Call me when you can actually show a remote exploit through the dongle.

      The problem is that you have a system that's not inherently safe - it merely rides on the unproven safety of one single component. A resilient system would have many barriers that you have to break down in order to gain access. This one has just one. For all we know, it has already been broken.

  • I had a client who actually bought holy Mary anti-virus stickers to put on the outside of the computer.

  • There might be a market for a defice that can be placed between any such 'required' dongles and a vehicle's actual systems. Something that can pass certain data in only one direction (read-only vehicle parameters) and block requests (and spoof handshake signals) should dongle attempt to make an unwanted request of the vehicle's systems.

    I can also see a market for such a device where emissions tests are done by reading the data port. Just tell the port filter to always reply with an 'all is well' code.

  • If you're worried about it, solve the problem at the communications layer. Wrap the dongle in such a way that it can't transmit or receive data. "What you're not getting the data? Wow that's strange. I have it plugged in." Either that or find another insurance company that doesn't track you. The fact that you've allowed a device to track you in the first place means that you've exposed yourself to risks, some overt such as your lead footed behavior is know a known quantity and inadvertent in terms of a
