Digital twins, being the virtual replicas of their physical counterparts, share the expected functional requirements and operational behavior of the underlying systems. Due to this fact, digital twins may act as a potential source of data breaches. Attackers may exploit the valuable knowledge about the system accessible through digital twins to put digital twins into a malicious state. We focus on potential attack strategies on digital twins ranging from digital twin's design to the dismissal phase. Next, we discuss defensive strategies to thwart the identified attacks on digital twins. Finally, we outline future research challenges that must be addressed to deal with malicious digital twins.
