  Advanced driver assistance systems (ADASs) were developed to reduce the
number of car accidents by issuing driver alert or controlling the vehicle. In
this paper, we tested the robustness of Mobileye, a popular external ADAS. We
injected spoofed traffic signs into Mobileye to assess the influence of
environmental changes (e.g., changes in color, shape, projection speed,
diameter and ambient light) on the outcome of an attack. To conduct this
experiment in a realistic scenario, we used a drone to carry a portable
projector which projected the spoofed traffic sign on a driving car. Our
experiments show that it is possible to fool Mobileye so that it interprets the
drone carried spoofed traffic sign as a real traffic sign.
