Orbital Escalation: Modeling Satellite Ransomware Attacks Using Game Theory

Ransomware has yet to reach orbit, but the conditions for such an attack already exist. This paper presents the first game-theoretic framework for modeling ransomware against satellites: the orbital escalation game. In this model, the attacker escalates ransom demands across orbital passes, while...
