Online extremism remains a persistent problem despite the best efforts of governments, tech companies and civil society. Digital technologies can induce group polarization to promote extremism and cause substantial changes to extremism (e.g., create new forms of extremism, types of threats or radicalization approaches). Current methods to counter extremism induce undesirable side‐effects (e.g., ostracize minorities, inadvertently promote extremism) or do not leverage the full potential of digital technologies. Extremism experts recognize the need for researchers from other disciplines, like information systems, to contribute their technical expertise for understanding and countering online extremism. This article aims to introduce the field of information systems to the issue of online extremism. Information systems scholars address technology‐related societal issues from a sociotechnical perspective. The sociotechnical perspective describes systems through a series of interactions between social (structure, people) and technical components (physical system, task). We apply the sociotechnical perspective to (1) summarize the current state‐of‐the‐art knowledge of 222 articles in a systematic multi‐disciplinary literature review and (2) propose specific research questions that address two questions (How do digital technologies augment extremism? How can we successfully counter online extremism?).

The goal of this dissertation is to develop a better understanding of how militias use the internet to connect with other militias, their members, and the public. The modern militia movement in the United States experienced a resurgence of late following a rapid decline in the early 2000s. Along with the drop in membership, the interest levels of researchers and law enforcement began to fade and as a result, a significant gap formed in the literature as it relates to our understanding of the groups’ activities. I address this gap by examining the online activities of the modern militia movement at three levels. Specifically, I examine how militias throughout the United States connect with each other through their official websites, how militias operating at different geographic levels connect with other websites, and how a regional militia uses Facebook to communicate with its members and the public. The three components of this dissertation reveal that the modern militia movement has experienced important changes in its online activity since 2013. Component I examines the breakdown in the nationwide network of militia websites that occurred between 2014 and 2017. Component II reveals the ways the networks surrounding three militia groups changed from 2013 to 2017 and the important role ideology plays in the connections between websites. Component III examines the ways one militia utilized Facebook during an eleven month period, including which content posted by the group had the highest likelihood of generating participation from visitors and the interactions that occurred in the most active discussions among visitors. Understanding how militias connect with each other and with individuals is an important step towards understanding the modern movement, its goals, and activities. A deeper understanding of these groups and their activities will provide a foundation for future research and assist law enforcement developing response strategies.

Within the short timeframe of a few months, a new terrorist group managed to solidify its presence in the Middle East in order to begin radicalizing and recruiting foreigners to fight jihad and declare an overarching goal of creating a purely Islamic State. DAESH quickly established their brand and a media strategy and became known worldwide for the high production value of their communication operations just as much as for their savage cruelty. The use of media has become vital to its overall success as a terrorist organization. Through targeted propaganda strategies, DAESH has managed to appeal to marginalized foreigners. While the populations of the Western world, largely opposed to DAESH, receive videos of beheadings and barbarity, potential recruits are inundated with images of state-building, charity work, and brotherhood. Concurrently, DAESH has managed to utilize the mainstream media landscape in order to further facilitate anti- Islamic rhetoric and intensify the air of mystery surrounding the organization. Through the sophisticated use of technology, as well as a detailed understanding and exploitation of human behavior and psychology, DAESH has managed to establish themselves as one of the most adept terror organizations, due in large part to the successful intersection of their communication operations with targeted propaganda strategies.

This report presents research carried out within the project (Ku2016/01373/D – Uppdrag till Totalförsvarets forskningsinstitut (FOI) att göra kartläggningar och analyser av våldsbejakande extremistisk propaganda) that has been assigned to the Swedish defence research agency by the Swedish Government. The project will continue until March 2019. The purpose of this report is to highlight various aspects of IS’s digital propaganda; How it is spread, what its content is, how the content varies over time, and how images are used in the propaganda. We have also studied the role of women and children in IS-propaganda, and how a youth culture called Jihadi cool has evolved with its own kind of clothing, music and cultural expressions. IS’s propaganda contains a variety of religious concepts and references, which IS sometimes use in a non-traditional way. Therefore, a chapter in this report describes how Islamic politico-religious language can be used to convey different kinds of messages

The configuration of the discourse of cyberterrorism in the Netherlands is a mix of public and private actors that have diverging views about whether cyberterrorism is a genuine security threat. How and why have several of these actors argued that it is a genuine security threat? What was their interest in doing so? Has cyberterrorism possibly been framed or hyped as a genuine security threat? This thesis examines the discourse of cyberterrorism in the Netherlands by examining the field, the position on cyberterrorism of the actors within this field, and finally, their levels of technological capital, legitimacy and authority. Considering the differences in these levels, this thesis contends that public and private actors have different interests in arguing that cyberterrorism is a threat. While public actors are concerned with the protection of Dutch cyberspace and the Dutch society, private actors, with the exception of Fox-IT, have multiple interests. This has led these private actors to frame or hype cyberterrorism as a genuine security threat, without the necessary background to base their statement on. Exceptional measures have led to the framing of exceptional times.
