Terrorist use of the Internet has become a focus of media, policy, and scholarly attention in recent years. Terrorists use the Internet in a variety of ways, the most important being for propaganda purposes and operations-related content, but it is also potentially a means or target of attack. This book presents revised versions of a selection of papers delivered at the NATO Advanced Research Workshop (ARW) on ‘Terrorists’ Use of the Internet’ held in Dublin, Ireland in June 2016. One aim of the workshop was to nurture dialogue between members of the academic, policy and practitioner communities, so the 60 delegates from 13 countries who attended the workshop included representatives from each of these. The participants encompassed a wide range of expertise (including engineering, computer science, law, criminology, political science, international relations, history, and linguistics) and the chapters contained herein reflect these diverse professional and disciplinary backgrounds. The workshop also aimed to address the convergence of threats. Following an introduction which provides an overview of the various ways in which terrorists use the Internet, the book’s remaining 25 chapters are grouped into 5 sections on cyber terrorism and critical infrastructure protection; cyber-enabled terrorist financing; jihadi online propaganda; online counterterrorism; and innovative approaches and responses. The book will be of interest to all those who need to maintain an awareness of the ways in which terrorists use the Internet and require an insight into how the threats posed by this use can be countered.

Public interest and policy debates surrounding the role of the Internet in terrorist activities is increasing. Criminology has said very little on the matter. By using a unique data set of 223 convicted United Kingdom–based terrorists, this article focuses on how they used the Internet in the commission of their crimes. As most samples of terrorist offenders vary in terms of capabilities (lone-actor vs. group offenders) and criminal sophistication (improvised explosive devices vs. stabbings), we tested whether the affordances they sought from the Internet significantly differed. The results suggest that extreme-right-wing individuals, those who planned an attack (as opposed to merely providing material support), conducted a lethal attack, committed an improvised explosive device (IED) attack, committed an armed assault, acted within a cell, attempted to recruit others, and engaged in non-virtual network activities and non-virtual place interactions were significantly more likely to learn online compared with those who did not engage in these behaviours. Those undertaking unarmed assaults were significantly less likely to display online learning. The results also suggested that extreme-right-wing individuals who perpetrated an IED attack, associated with a wider network, attempted to recruit others, and engaged in non-virtual network activities and non-virtual place interactions were significantly more likely to communicate online with co-ideologues.

This article is a revised and updated version of the 2015 VOX-Pol report ‘What are the Roles of the Internet In Terrorism? Measuring Online Behaviors of Convicted UK Terrorists.’

This report seeks to contribute to public and policy debates on the value of social media disruption activity with respect to terrorist material. We look in particular at aggressive account and content takedown, with the aim of accurately measuring this activity and its impacts. Our findings challenge the notion that Twitter remains a conducive space for Islamic State (IS) accounts and communities to flourish, although IS continues to distribute propaganda through this channel. However, not all jihadists on Twitter are subject to the same high levels of disruption as IS, and we show that there is differential disruption taking place. IS’s and other jihadists’ online activity was never solely restricted to Twitter. Twitter is just one node in a wider jihadist social media ecology. We describe and discuss this, and supply some preliminary analysis of disruption trends in this area.

The use of the Internet, particularly social media, by violent extremists and terrorists and their supporters received an increasing amount of attention from policymakers, media, Internet companies, and civil society organisations in 2017. In addition to politicians stepping-up their rhetoric regarding the threat posed by consumption of and networking around violent extremist and terrorist online content, prominent and heavily trafficked social media platforms also took a stronger stand on the issue this year, which caused civil liberties organisations considerable disquiet. This report treats developments in the violent extremist and terrorist online scene(s) and responses to them in the 12-month period from 1 December 2016 to 30 November 2017.
