Car Hacking is 'Distressingly Easy'
Bruce66423 points out a piece from the Economist trying to rally support for pressuring legislators and auto manufacturers to step up security efforts on modern, computer-controlled cars. They say,
Taking control remotely of modern cars, for instance, has become distressingly easy for hackers, given the proliferation of wireless-connected processors now used to run everything from keyless entry and engine ignition to brakes, steering, tyre pressure, throttle setting, transmission and anti-collision systems. Today's vehicles have anything from 20 to 100 electronic control units (ECUs) managing their various electro-mechanical systems. ... The problem confronting carmakers everywhere is that, as they add ever more ECUs to their vehicles, to provide more features and convenience for motorists, they unwittingly expand the "attack surface" of their on-board systems. In security terms, this attack surface—the exposure a system presents in terms of its reachable and exploitable vulnerabilities—determines the ease, or otherwise, with which hackers can take control of a system. ... There is no such thing as absolute security. [E]ven firms like Microsoft and Google have been unable to make a web browser that cannot go a few months without needing some critical security patch. Cars are no different.
Why should a hack of the navigation or audio system allow access to the braking system? Why hasn't the DOT mandated an air gap between critical vehicle operation systems(braking, acceleration, ignition, steering, transmission, etc) and all others.
Personally, I want a hackable car. What I do not want is a /remotely/ hackable car.
I want a vehicle where I, as the owner, can access all its bits-n-bobs - even the digital ones - to tune it as I desire. I do not want a car whose computers are so saddled down with "security" that the only ones who can access its electronic brains are "authorized" technicians who have paid tens of thousands of dollars for the appropriate software and hardware. Too often I see "security" being used by automobile manufacturers as an excuse to lock out the owners (or even ordinary mechanics) from modifying - or even diagnosing - the vehicle without first tithing to the manufacturer for the privilege.
Of course, only I as owner (or any I authorize) should be allowed to adjust my car in this way; obviously, I do not want any nefarious parties to alter my car's settings - especially not while I am driving! But while this is something the designers and manufacturers need to keep in mind, so far I am unaware of /any/ successful attempt to "hack" a moving car. Of course, if a nefarious individual gets access to the OBDII port on my car, there's no end to the damage he could do, but no computer (or car! think "cutting the brake lines") is safe if somebody has physical access to it.
So forgive me if I interpret these worried cries about how my car might be "hacked" less as an earnest warning about my vehicle's vulnerability to malicious actors and more as another attempt by the manufacturer to gouge the owner out of even more money just so he can continue to tinker with his own property.
That's what I do, I have a 1998 car which I intend to keep for the rest of my life. It still has some electronics (ECU, ABS)...
And those electronics are probably going to be one of the biggest issues with keeping that car going. Most mechanical parts can be repaired, be made, or sourced from junk yards.A lot of classic cars also have other companies making replacement parts. For example, you can build a brand new replica of a 1963 Corvette if you would want to as every part for them is in reproduction by one company or a company.
There has been a bit of concern regarding the electronics in cars that have been made in the last 20-30 years though. They will wear out as a car is a very harsh environment for such things. Since the auto manufacturers are not that big on creating competition for their parts, they don't make it easy for other companies to reproduce these components and they also only make them for a set number of years. Besides, they don't want you to keep that car for decades. If you do that, you won't be buying a new one. Eventually electronic replacement parts for a car built in 1998 are going to run out and there won't be any replacements. Without a functional ECU, you won't be able to start the engine.
If you are lucky enough for your car to be popular with racers or some other group that likes to modify its engine, then there may be aftermarket ECU systems available. But that's going to cost a lot in most cases.
