Adversarial Machine Learning against Tesla's Autopilot
Researchers have been able to fool Tesla's autopilot in a variety of ways, including convincing it to drive into oncoming traffic. It requires the placement of stickers on the road.
Abstract: Keen Security Lab has maintained the security research work on Tesla vehicle and shared our research results on Black Hat USA 2017 and 2018 in a row. Based on the ROOT privilege of the APE (Tesla Autopilot ECU, software version 18.6.1), we did some further interesting research work on this module. We analyzed the CAN messaging functions of APE, and successfully got remote control of the steering system in a contact-less way. We used an improved optimization algorithm to generate adversarial examples of the features (autowipers and lane recognition) which make decisions purely based on camera data, and successfully achieved the adversarial example attack in the physical world. In addition, we also found a potential high-risk design weakness of the lane recognition when the vehicle is in Autosteer mode. The whole article is divided into four parts: first a brief introduction of Autopilot, after that we will introduce how to send control commands from APE to control the steering system when the car is driving. In the last two sections, we will introduce the implementation details of the autowipers and lane recognition features, as well as our adversarial example attacking methods in the physical world. In our research, we believe that we made three creative contributions:
- We proved that we can remotely gain the root privilege of APE and control the steering system.
- We proved that we can disturb the autowipers function by using adversarial examples in the physical world.
- We proved that we can mislead the Tesla car into the reverse lane with minor changes on the road.
You can see the stickers in this photo. They're unobtrusive.
This is machine learning's big problem, and I think solving it is a lot harder than many believe.
