Does exposure to cyber terrorism prompt calls for retaliatory military strikes? By what psychological mechanism does it do so? Through a series of controlled, randomized experiments, this study exposed respondents (n = 2,028) to television news reports depicting cyber and conventional terror attacks against critical infrastructures in the United States, United Kingdom and Israel. The findings indicate that only lethal cyber terrorism triggers strong support for retaliation. Findings also confirm that anger bridges exposure to cyber terrorism and retaliation, rather than psychological mechanisms such as threat perception or anxiety as other studies propose. These findings extend to the cyber realm a recent trend that views anger as a primary mechanism linking exposure to terrorism with militant preferences. With cyber terrorism a mounting international concern, this study demonstrates how exposure to this threat can generate strong public support for retaliatory policies, depending on the lethality of the attack.
This study explores the internal dynamics and networks of terrorist groups in cyberspace—in particular, Al-Qaeda and the Islamic State of Iraq and al-Sham (ISIS). Using a “Global Cyberterrorism Dataset” that features data on cyberterror attacks between 2011 and 2016, this research analyzes these two terrorist groups through the lens of a cyber-conflict theory that integrates conflict theory with Jaishankar’s space transition theory. Through a network analysis methodology, we examine the invisible relationships and connections between the national origins and target countries of cyberterror attacks. The analysis focuses on the networks of national origins of terrorists and victims, network structures of Al-Qaeda and ISIS actors, and clustering networks of Al-Qaeda and ISIS cyberterrorists. Results indicate that terror in cyberspace is ubiquitous, more flexible than traditional terrorism, and that cyberattacks mostly occurred within the countries of origin. We conclude by discussing the complex features of cyberterror networks and identify some of the geostrategic implications of the divergent cyber strategies adopted by Al-Qaeda and ISIS.
Does exposure to cyberattacks influence public support for intrusive cybersecurity policies? How do perceptions of cyber threats mediate this relationship? While past research has demonstrated how exposure to cyberattacks affects political attitudes, the mediating role played by threat perception has been overlooked. This study employs a controlled randomized survey experiment design to test the effect of exposure to lethal and nonlethal cyberattacks on support for different types of cybersecurity policies. One thousand twenty-two Israeli participants are exposed to scripted and simulated television reports of lethal or nonlethal cyberattacks against national infrastructure. Findings suggest that exposure to cyberattacks leads to greater support for stringent cybersecurity regulations, through a mechanism of threat perception. Results also indicate that different types of exposure relate to heightened support for different types of regulatory policies. People exposed to lethal cyberattacks tend to support cybersecurity policies that compel the government to alert citizens about cyberattacks. People who were exposed to nonlethal attacks, on the other hand, tend to support oversight policies at higher levels. More broadly, our research suggests that peoples’ willingness to accept government cybersecurity policies that limit personal civil liberties and privacy depends on the type of cyberattacks to which they were exposed and the perceptions associated with such exposure.
To what extent can cyberattacks wreak havoc and terrorize modern society? Until now, this question has revolved around the potential of cyber operations to cause physical destruction or other material harm. In this paper, we propose a broader interpretation. We submit that assessing cyber-threats through the prism of physical destruction has obscured the human dimension of the threat. Instead, we propose calculating the gravity of cyberattacks by measuring psychological distress. This approach recognizes that even seemingly inconsequential cyberattacks can levy tremendous damage by traumatizing civilians, undermining societal cohesion, and exacerbating cycles of violence. To test whether cyberattacks cause significant individual harm, we employ an internal meta-analysis looking at eighteen studies conducted in three countries over 6 years. Across these studies, we exposed 6,020 respondents to simulated cyberattacks and conventional attacks. We conclude that cyberattacks can cause high levels of psychological harm—equal even to that caused by conventional political violence and terrorism. This finding overturns a widely accepted view that cyberattacks are a mere irritant at best and a threat to information security at worst. Through this lens, the findings suggest that even nonphysically destructive cyberattacks can trigger consequences that constitute a legally defined armed attack that permits using armed force in self-defense. We conclude by discussing how the onset of psychological distress generates political pressure in support of retaliation and can lead to military escalation.
