Previous research on terrorist use of the Internet generally discusses the opportunities offered by the Internet to terrorist groups (Tsfati & Weimann, 2002; Weimann, 2006; Holt et al., 2015; Rudner, 2016). Such accounts implicitly view the interaction between the Internet and the user as uni-directional (i.e. exposure to Internet content may cause behaviour change). This lacks an acknowledgement that not every potential user will make use available opportunities, nor use these in the same way. The degree to which an individual makes use of an opportunity is modulated based upon their goals, plans, values, beliefs, and experiences (Norman, 1988). At present, there are only three data-driven studies examining how convicted terrorists have used the Internet: Von Behr et al., 2013, Gill et al., 2014, and Gill and Corner 2015. These studies shift the focus from the Internet as a potentially causal factor to how individuals use the Internet based upon their motivations, needs, expectations, and histories. They acknowledge, in other words, the way in which the interaction between Internet and user is a two-way person-situation interactive process in which the individual leads the way. Reported herein are two complementary pieces of research, one large scale and based on open source data and another smaller scale and based on closed sources, that build significantly upon the above described research.

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.
