This study addresses the vulnerability of autonomous systems to phantom attacks, where adversaries project deceptive illusions that are mistaken for real objects. Initial research assessed attack success rates from various distances and angles. Experiments used two setups: a black-box with DJI Mavic Air, and a white-box with Tello drone equipped with YOLOv3. To counteract these threats, the DeGhost deep learning framework was developed to distinguish between real objects and illusions, testing it across multiple surfaces and against top object detection models. DeGhost demonstrated excellent performance, achieving an AUC of 0.998, with low false negative and positive rates, and was further enhanced by an advanced Fourier technique. This study substantiates the risk of phantom attacks and presents DeGhost as an effective security measure for autonomous systems.
