Very interesting, and a potential concern you wouldn’t even be aware of. Score another one for the analogue supercar!

Now, this is of interest to me personally because it is sort of in my field. It sort of lends itself to the PCM issues, but also the architecture of the car is extremely safe. What does this mean? It means that your car can't be "exploited" by others.

For instance:

Means a sophisticated hacker could cause brake issues via the radio. Insanity.

This is precisely my “field”, and this is largely incorrect. The “braking system” (ABS/ESP) is on the high-speed motion-control subnet (“CAN-C”), and the audio system is on the feature and comfort subnet (“CAN-B”). CAN-C signals (the data elements in messages) that are needed by the audio system (such as vehicle speed) are routed through the gateway which, in the case of the KL, is the BCM. The are ECUs that are on both buses (for functional reasons), but don’t have the ability to gate arbitrary messages.

There isn’t one specific signal received by the ABS/ESP ECU that would trigger a brake application, and there’s nothing in the radio software to transmit an arbitrary message thus applying the brakes through a “hack”, while not impossible, would require a high level of sophistication and a lot of confidential information. There isn’t a lot of data security, but there are “extra” rationality signals transmitted to make anything of the sort wildly improbable even with access to the “right” information.

Mike, interesting. I guess more the point is (What Miller gets at) as cars become more interconnected proper architecture will lay a vital role in preventing “Wardriving” like hacking. Having a WiFi point, for instance in new cars, seems like a fantastic vector to attack a vehicle.

Point taken, but most cars simply don’t have a sufficiently sophisticated architecture so as to make that a risk. Dumb is good, until the OEMs broadly adopt Automotive Ethernet, and then they’ll have to address this. Fortunately, they’ll have the bandwidth needed to do precisely that…

The most hackable vehicles include the 2014 Jeep Cherokee, the 2015 Cadillac Escalade and the 2014 Toyota Prius. The most secure cars include the Dodge Viper, the Audi A8, and the Honda Accord, according to an interview the researchers had with Dark Reading.

Now, this is of interest to me personally because it is sort of in my field. It sort of lends itself to the PCM issues, but also the architecture of the car is extremely safe. What does this mean? It means that your car can’t be “exploited” by others.

For instance:

“We can’t say for sure we can hack the Jeep and not the Audi,” Valasek told Dark Reading. “But… the radio can always talk to the brakes” because both are on the same network.

Means a sophisticated hacker could cause brake issues via the radio. Insanity.
