Additionally, a change was made to lock down access to individual Jeeps over the Internet. This discovery led to the recall of 1.4 million vehicles, with Chrysler sending out firmware upgrades on USB drives to patch the vulnerability. The duo were able to scan the internet for further targets, and could even track various Chrysler automobiles around the country thanks to GPS and their in-dash entertainment systems. Security researchers and were able to remotely take control of a Jeep Cherokee, with just a laptop and a 3G data connection. While many wrote off these concerns as unrealistic, the uncomfortable truth came home to roost in 2015. In vehicles, not only are the embedded systems connected to the internet, but they’re also capable of controlling vital safety systems. and remotely hacked into a Jeep, disabling its brakes remotely and sending it careening into a ditch.As any hacker knows, a connected computer is a vulnerable computer. ![]() It raises the question - what can be done to protect these vehicles from unscrupulous types? How can we give the user ultimate control over who has access to the data network that snakes throughout their vehicle? One possible solution I’m looking at today is the addition of internet killswitches. This can range from the mundane, like reading location data from the navigation system to more nefarious exploits capable of putting motorists at risk. Combine this with Bluetooth, WiFi, and cellular connectivity - it’s unlikely you can purchase a vehicle today without at least one of these built in - and the attack surface has grown far beyond the physical bounds of bumpers and crumple zones surrounding the driver.Ĭyberattackers can now compromise vehicles from the comfort of their own homes. But alongside antitheft security advances, modern vehicles gained an array of electronic controls covering everything from the entertainment system to steering and brakes. Technology rose up to combat this, you may remember the immobilizer systems that added a chip to the ignition key without which the vehicle could not be started. If both switches are open, it's a double line of defense.Back in the good old days of carburetors and distributors, the game was all about busting door locks and hotwiring the ignition to boost a car. I therefore decided to install a momentary switch as well-even if I leave the toggle switch activated, the momentary switch still prevents theft. Since the whole point of installing this switch, for me, is that I often forget to remove the key from the car, betting that I will remember to turn off the toggle switch each time I leave the car seems imprudent. If you don't have any switches you don't use, consider wiring another switch to control the function of something you do use and assigning the original switch the killswitch function. Other rarely used switches could also be used-though I'm not sure of the legal implications, one could use the emergency flasher button. This is an entirely useless function-but it's a toggle-style switch which would not look at all out of place. My Celica has a button in the dash which prevents the passenger window from rolling down. However, this too is probably easily discovered by any but an amateur thief-there are only so many spots one can hide the switch and still keep it accessible.Īs such, I personally decided to hide the switch in plain sight. There are a few ways you can do this if there's a hiding place that's easily reached from the driver's seat, that's one option. Therefore, it is important to conceal your switch. If someone breaks into your car and tries to hotwire it, they're probably familiar with theft prevention measures like this one.
