Keyless entry has become a standard feature on virtually all cars, where once it was a luxury option. However, it’s also changed the way that thieves approach the process of breaking into a car. After recent research, [HackingIntoYourHeart] claims that many modern Honda and Acura vehicles can be accessed with a simple replay attack using cheap hardware.
It’s a bold claim, and one that we’d love to see confirmed by a third party. The crux of the allegations are that simply recording signals from a Honda or Acura keyfob is enough to compromise the vehicle. Reportedly, no rolling code system is implemented and commands can easily be replayed.
Given these commands control features like unlocking the doors, opening the trunk, and even remote starting the vehicle, it’s a concerning situation. However, it’s also somewhat surprising. Rolling code technology has been around for decades, and makes basic replay attacks more difficult. Range extender attacks that target keyfobs sitting inside homes or gas stations are more common these days.
Whether Honda has made a security faux pas, or if there’s something more at play here, remains to be seen. If you’ve got more information, or have been able to recreate the same hack on your own Honda, be sure to let us know.
This week [Geohot] announced the launch of his self-driving car hardware. This is the natural extension of his proof-of-concept shown off in December which he parlayed into a Silicon Valley startup called comma.ai. [Geohot], whose real name is [George Hotz], is well known for jailbreaking the iPhone and making Sony look like idiots when they retroactively crippled Linux support on PS3. He has hardware chops.
Initial self-driving add-on hardware only works with Honda and Acura models that already have lane-keeping assist features because those vehicles already have built-in front radar. The package, which replaces the rear view mirror, adds a front facing camera. Those lucky (or brave, foolish, daring?) beta users can trade $999 and $24/month for what is currently a green 3D printed enclosure with some smartphone-like hardware inserted.
The company has taken an interesting approach to acquiring data needed for this particular flavor of self-driving. [Hotz] is teasing a chance at beta test invites to those who contribute driving data to the company. This is as simple as downloading an app to your phone and letting it roll from your windshield as you go bumper to bumper from Mountain View to San Francisco. That’s right, the plan is to support just that stretch of the nation’s highway system — although [Hotz] did make a brazen estimate of 90% of commutes for 90% of users within a year. Hey, it’s a startup so it’s either that, selling to a bigger fish, or closing their doors.
That narrow route support is actually an interesting constraint. In fact, the company is most interesting because of its chosen constraints: a small subset of cars, a chosen stretch of highway, and dare we say sanity when it comes to self-driving expectations. Grandiose claims have the general public thinking a vehicle with no human driver will slide up to your stoop and take you anywhere you want to go. That is a dauntingly difficult engineering challenge (dare we say impossible). What [Hotz] is selling is a more stress-free commute, not a nap in the back seat. You still need to be paying attention at all times.
Will this system work? Undoubtedly the engineering is possible (Tesla is already doing it). The biggest question mark that remains is human nature. This system demands your attention even though you’re doing nothing. That seems unrealistic — users are bound to lapse in attention much more frequently than if they were the primary driver. The question then becomes, will people pay attention at the very rare yet very crucial moments, and can a system like this prevent more fatal accidents than it causes?
We know what you’re thinking. “I have this Acura NSX, but my friends just won’t think I’m cool unless I have a Ferrari F50.” You know what? You’re right. To save yourself from that kind of ridicule, you can simply carry out a ridiculous body mod to make your poor NSX live up to your friends expectations. It only took massive amounts of fiberglass, foam, and bondo to get this NSX looking the way the guy wanted it. We have to wonder if there was any performance hit with the additional weight, then again, he may have removed enough metal panels to compensate. While we may joke about it, we really do have some respect for the amount of work he put into this thing. The finished job is simply amazing, in terms of reproduction of the original. Kudos crazy car modder guy.
