Two images side by side. One shows a laptop opened to a map view with a vehicle model showing a vehicles location. A transparent overlay shows various blue-ish buttons for sending commands to the vehicle. The image on the right is of the interior of a Nissan Leaf. Visible are the very edge of the steering wheel, the center dash including the infotainment display, vents, and shifter, and part of the right side of the dash. Passenger and driver legs are just barely visible at the bottom of the image.

Hack Turns Nissan Leaf Into Giant RC Car

June 24, 2025 by 27 Comments

As cars increasingly become computers on wheels, the attack surface for digital malfeasance increases. The [PCAutomotive] group shared their exploit for turning the 2020 Nissan Leaf into 1600 kg RC car at Black Hat Asia 2025.

Starting with some scavenged infotainment systems and wiring harnesses, the group built test benches able to tear into vulnerabilities in the system. An exploit was found in the infotainment system’s Bluetooth implementation, and they used this to gain access to the rest of the system. By jamming the 2.4 GHz spectrum, the attacker can nudge the driver to open the Bluetooth connection menu on the vehicle to see why their phone isn’t connecting. If this menu is open, pairing can be completed without further user interaction.

Once the attacker gains access, they can control many vehicle functions, such as steering, braking, windshield wipers, and mirrors. It also allows remote monitoring of the vehicle through GPS and recording audio in the cabin. The vulnerabilities were all disclosed to Nissan before public release, so be sure to keep your infotainment system up-to-date!

If this feels familiar, we featured a similar hack on Tesla infotainment systems. If you’d like to hack your Leaf for the better, we’ve also covered how to fix some of the vehicle’s charging flaws, but we can’t help you with the loss of app support for early models.

Jailbreaking Tesla Infotainment Systems

August 5, 2023 by 22 Comments

With newer cars being computers on wheels, some manufacturers are using software to put features behind a paywall or thwarting DIY repairs. Industrious hackers security researchers have taken it upon themselves to set these features free by hacking a Tesla infotainment system. (via Electrek)

The researchers from TU Berlin found that by using a voltage fault injection attack against the AMD Secure Processor (ASP) at the heart of current Tesla models, they could run arbitrary code on the infotainment system. The hack opens up the double-edged sword of an attacker gaining access to encrypted PII or a shadetree mechanic “extracting a TPM-protected attestation key Tesla uses to authenticate the car. This enables migrating a car’s identity to another car computer without Tesla’s help whatsoever, easing certain repairing efforts.” We can see this being handy for certain other unsanctioned hacks as well.

The attack is purported as being “unpatchable” and giving root access that survives reboots and updates of the system. Since AMD is a vendor to multiple vehicle companies, the question arises as to how widely applicable this hack is to other vehicles suffering from AaaS (Automotive as a Service).

New Cars Will Nickel-and-Dime You – It’s Automotive As A Service

December 30, 2021 by 230 Comments

Every few years, someone pushing a startup to investors comes up with an acronym or buzzword which rapidly becomes the new hotness in those circles. One of the most pernicious is “as a Service,” which takes regular things and finds a way to charge you a regular fee to use them.

Automotive companies just absolutely loved the sound of this, and the industry is rapidly moving to implement subscription services across the board. Even if there’s hardware in your car for a given feature, you might find you now need to pay a monthly fee to use it. Let’s explore how this came about, and talk about which cars are affected. You might be surprised to find yours already on the list.
