"That CMU is full of remote exec bugs," wrote security researcher Aris Adamantiadis on Twitter. Other researchers who looked at the MZD Connect firmware shared this opinion.

Below is a sample config for the dataRetrieval_config.txt file, which the researcher shared via email as an example:įurthermore, Turla says one of his work managers believes these flaws could be abused to install RATs (Remote Access Trojans) on Mazda cars. Nonetheless, the researcher said that some malicious hackers could create a botnet for Mazda cars. "It is possible although I don't have a PoC about it," he said in an email. Nonetheless, the researcher doesn't rule out such scenarios, admitting he only scratched the surface with this issue. This automatically means you can't use the infotainment flaws to start the car's motor and hijack cars. For example, the car must be in accessory mode, or the engine must be running, before the script would execute. "Imagine an autoplay feature on Windows which executes a script directly."ĭespite this benefit, the attack has its downsides. "No need for a user interaction, you just need to insert the USB flash drive in the USB port of your car," the researcher told Bleeping Computer. Turla says that his script is just perfect to re-enable SSH support in the MZ Connect system after the feature has been disabled in previous firmware updates.įurthermore, the attack executes automatically right after the user inserts the USB inside a car's dashboard. I just want to make it simpler in order to give some awareness.
Thus, I decided to create the mazda_getInfo repo, which demonstrates that the USB port is an attack surface for a Mazda car's infotainment system by echoing outputs from two known *nix commands through the jci-dialog which appears as a dialog box in an infotainment system. I studied how MZD-AIO-TI (MZD All In One Tweaks Installer from Trezdog44) works and discovered that the tweak included executing a tweak.sh script through cmu_dataretrieval.up and dataRetrieval_config.txt.

So I did some research on how is it done including how to create apps. In an email, Turla shared how his project works under the hood. Since MZD Connect is a *NIX-based system, anyone can create scripts and execute more intrusive attacks.

Turla's mazda_getInfo, which he open sourced on GitHub last week, allows anyone to copy a collection of scripts on their USB flash drive, insert it into their car's dashboard, and execute malicious code on the car's MZD Connect firmware.ĭuring his tests, Turla executed simple attacks like printing text on the car's dashboard or echoing terminal commands. I also have a couple of friends in the Philippines who are currently into car hacking research." "I also want to test my car just for my personal research as I enjoyed my first visit at the Car Hacking Village during DEF CON 24 in Vegas last year. "I just wanted to check what were the possible attack vectors for my car," Turla told Bleeping. Speaking to Bleeping Computer, Turla said he started working on the project after recently purchasing a Mazda car. The knowledge shared through these two projects has been the base of mazda_getInfo, a project put together by Bugcrowd application security engineer Jay Turla, which automates Mazda car hacks. One of the most well-designed tools is MZD-AIO-TI (MZD All In One Tweaks Installer).
Since then, the Mazda car owner community has been using these "hacks" to customize their cars' infotainment system to tweak settings and install new apps. The issues have been discovered and explored by the users of the Mazda3Revolution forum back in May 2014. Mazda cars with next-gen Mazda MZD Connect infotainment systems can be hacked just by plugging in a USB flash drive into their dashboard, thanks to a series of bugs that have been known for at least three years.
