The parallel universe of cyberspace, created by computer networks, ones, and zeros, has changed the rules of the game. It would be inevitable for crisis management research to remain unaffected by the new challenges arising. The present article delves into the underexplored concept of cyber crises, by initiating an academic problematization of crisis conceptualization. Drawing from transboundary crisis management theory, it examines two major cyberattacks, the 2017 WannaCry ransomware attack and the 2016 hacking of the DNC, and explores an empirical puzzle: why are these cases not characterized as crises even though they fit already existing definitions? The article contributes to the theory of transboundary crises by shedding light on previously overlooked cyber crisis characteristics and attempting to propose a definition of cyber crises. The way we perceive crises has a direct impact on how we manage them. Broadening the research agenda and understanding the concept of a cyber crisis could pave the way for a more effective and proactive response to new threats, which is what the following pages attempt to demonstrate.
