Abstract This article argues that the growing involvement of civilians in activities on the digital battlefield during armed conflicts puts individuals at risk of harm and contributes to the erosion of the principle of distinction, a cornerstone of international humanitarian law (IHL). The article begins by outlining the ongoing trend of civilianization of the digital battlefield and puts forward brief scenarios to illustrate it. It then examines the narrow circumstances under which such forms of civilian involvement may qualify as direct participation in hostilities under IHL, and discusses what this means for the individuals concerned, particularly from the perspective of their loss of protection under the law. The analysis shows that certain types of State conduct which put civilians in harm's way by inducing them to directly participate in hostilities may constitute standalone violations of IHL and human rights law obligations. Beyond these specific prescriptions, the encouragement of civilian involvement undermines the principle of distinction, with dangerous ripple effects on the interpretation of those rules of IHL that flow from it. Accordingly, the article concludes that States should act to reverse the trend of civilianization of the digital battlefield and refrain as much as possible from involving civilians in the conduct of cyber hostilities.
