Hackers Demand Automakers Get Serious About Security

wiredmikey writes: In an open letter to Automotive CEOs, a group of security researchers has called on automobile industry executives to implement five security programs to improve car safety and build cyber-security safeguards inside the software systems powering various features in modern cars. As car automation systems become more sophisticated, they need to be locked down to prevent tampering or unauthorized access. The Five Star Automotive Cyber Safety Program outlined in the letter asked industry executives for safety by design, third-party collaboration, evidence capture, security updates, and segmentation and isolation. Vehicles are "computers on wheels," said Josh Corman, CTO of Sonatype and a co-founder of I am the Cavalry, the group who penned the letter (PDF). The group aims to bring security researchers together with representatives from non-security fields, such as home automation and consumer electronics, medical devices, transportation, and critical infrastructure, to improve security.

      Nothing is going to happen until a serious mishap occurs.

      Meanwhile the automakers looks into strange hacks instead of proper physical segmentation and gatewaying. They do have a gateway, but it is just a gateway between different IP address series on the same physical net in some cases - in order to save money on hardware. So a rogue unit can just look at the different series and fake it being a different type of unit causing interesting things to happen.

      What I am afraid of is what happens after. There is a difference between security from remote attackers, and security from "jailbreakers". For example, my Android phone is just as secure rooted as not.

      My fear is that what steps would be taken would force the car into the shop for any minor issue. Already, one automaker, if you change the battery out, the vehicle will refuse to start until the vehicle goes into the dealership and the battery is "registered" into the ECM.

      Automakers should just keep stuff isolated. The radio should not have access to the brakes. Hell, the radio should not even be on the CAN. It should just be vital components, and have the doodads be stuck on another bus that can be "dirty".

  6. Shouldn't be necessary, but if it is... by Anonymous+Brave+Guy · · Score: 4, Interesting

    It's kinda terrifying that the people making fast, heavy lumps of metal with computerised control systems don't already routinely isolate those control systems from any other computerised technologies in the vehicle, particularly any that can interact remotely. They shouldn't need to be publicly admonished about the dangers of these situations. Don't these organisations employ actual engineers any more?

    But given that it does seem to be necessary to make a public display of this -- which presumably removes any plausible deniability if the auto makers do get sued after an accident later, so I can believe it will at least get their attention -- I'm glad it seems to be a responsible group with the right motivations who are starting the ball rolling. If it were just a bunch of lawyers or insurers, the general public could write the campaign off as the signatories just looking out for their own interests.

      My 2002 Jetta's stock stereo system is wired to the CAN bus. This means when I run an in-car-diagnostic with the little dongle connected to the computer port in the driver's seat, that the stereo system is part of the diagnostics. It actually told me one of the speakers was broken/disconnected which I was able to leverage another $100 off the price when I bought it used. ... Turned out, it was literally disconnected. Easy DIY fix ;)

      Anyway, my car has not internet connectivity. But I bet the newer models have stereos that integrate GPS, Satellite Radio, and internet services. Theoretically, both satellite radio and web services are potential attack vectors into the stereo, and if you can manipulate the firmware on the stereo to be a CAN bus master, you can now talk to anything in the car.

      So either take the entertainment stuff off the CAN bus, or install some sort of CAN router/firewall, that allows the rest of the car to talk to the stereo, but doesn't let the stereo talk to the rest of the car.

      You are totally ignoring the base issue: The fact that its so easy to get access to any part of the system.

      Reflashing a "faulty" component isn't what people are worried about. It's the combination of Wifi/remote accessable parts of a system, that once gotten into leads to total control.

      Imagine a virus that is able to jump from car to car once cars are able to simply mesh-hotspot to each other.

      Reflashing the stereo means nothing when the entire system is compromised at 80mph.

      This is clearly a case of prioritising convenience over security, which you're welcome to do as your own personal preference but I would never choose myself.

      This data is used to help triage the severity of the crash before the EMTs roll out.

      Well that's probably the single most disturbing thing I've seen in this whole discussion. Are you really telling me that in the event of a known road traffic accident, which is severe enough that no-one on the scene can immediately respond to verbal contact, they don't routinely send the full works where you are?

      In any case, I would point out that this is purely status reporting, i.e., read-only data. There is no need for anyone to control anything remotely in this situation.

      Also, in extreme cases, the OnStar / Bluelink / et al. system can actively end a felon's joyride by cutting throttle, braking, or cutting the engine entirely. Then it can honk and flash the lights to attract the authorities' attention.

      This is my main problem with the whole debate: any system that can do this kind of thing can also be used for less welcome purposes.

      Car theft is essentially a solved problem without any remote control needed. Technologies like immobilisers have become so good that stealing the car keys has been the preferred technique for some time. Trackers, which need no integration with any control system, provide an effective deterrent and means for police to locate a vehicle that has literally been put on the back of a lorry.

      Again, YMMV, but personally I would rather be careful about where I keep my keys than risk a hostile party, or simply a human error or software bug, doing something like cutting the engine and applying the brakes when I'm driving at high speed or through a hazardous area.

      These vehicles overwhelmingly share a single bus between everything including powertrain and infotainment. If you can control the infotainment system you can control the diagnostic bus. The infotainment system now commonly includes internet access, so it's not even necessary to be near the vehicle to gain attack surface.

      Has anyone in fact demonstrated such a hack, so far? Nope. Does that mean it's not a realistic threat? Also nope. Indeed, it's becoming a more realistic threat as more internet-connected features are being added to autos.

    One of the simplest ways to lock down a computer is to physically lock it away from access. Originally car-makers did that --you needed physical access to the computer (usually inside locked hood compartment) to do anything to it. Now they have connected it to radio waves. That is the main security hole. Go back to a solid wired-only connection, with the connection point(s) behind locked doors, and a significant chunk of the security problems goes away.
