Cyberterrorism and cybercrime present new challenges for law enforcement and policy makers. Due to its transnational nature, a real and sound response to such a threat requires international cooperation involving participation of all concerned parties in the international community. However, vulnerability emerges from increased reliance on technology, lack of legal measures, and lack of cooperation at the national and international level represents real obstacle toward effective response to these threats. In sum, lack of global consensus in terms of responding to cyberterrorism and cybercrime is the general problem. Terrorists and cyber criminals will exploit vulnerabilities, including technical, legal, political, and cultural. Such a broad range of vulnerabilities can be dealt with by comprehensive cooperation which requires efforts both at the national and international level. “Vulnerability-Comprehensive Cooperation-Freedom Scale” or “Ozeren Scale” identified variables that constructed the scale based on the expert opinions. Also, the study presented typology of cyberterrorism, which involves three general classifications of cyberterrorism; Disruptive and destructive information attacks, Facilitation of technology to support the ideology, and Communication, Fund raising, Recruitment, Propaganda (C-F-R-P). Such a typology is expected to help those who are in a position of decision-making and investigating activities as well as academicians in the area of terrorism. The matrix for international cooperation and vulnerability assessment is expected to be used as a model for global response to cyberterrorism and cybercrime.

In this article, we conduct a comprehensive study of online antagonistic content related to Jewish identity posted on Twitter between October 2015 and October 2016 by UK-based users. We trained a scalable supervised machine learning classifier to identify antisemitic content to reveal patterns of online antisemitism perpetration at the source. We built statistical models to analyze the inhibiting and enabling factors of the size (number of retweets) and survival (duration of retweets) of information flows in addition to the production of online antagonistic content. Despite observing high temporal variability, we found that only a small proportion (0.7%) of the content was antagonistic. We also found that antagonistic content was less likely to disseminate in size or survive for a longer period. Information flows from antisemitic agents on Twitter gained less traction, while information flows emanating from capable and willing counter-speech actors—that is, Jewish organizations—had a significantly higher size and survival rates. This study is the first to demonstrate that Sampson’s classic sociological concept of collective efficacy can be observed on social media (SM). Our findings suggest that when organizations aiming to counter harmful narratives become active on SM platforms, their messages propagate further and achieve greater longevity than antagonistic messages. On SM, counter-speech posted by credible, capable and willing actors can be an effective measure to prevent harmful narratives. Based on our findings, we underline the value of the work by community organizations in reducing the propagation of cyberhate and increasing trust in SM platforms.

This chapter analyses the Norwegian authorities’ presence on Twitter during the 22 July 2011 terrorist attacks. Twitter activity by two official institutions is analysed in particular, namely, the blood bank at Oslo University Hospital and the Norwegian Police Security Services (PST). Our findings show that the Norwegian authorities were almost completely absent on Twitter during the critical hours of the terrorist attack, and that there was no coordination and synchronisation of communication from the authorities. This official silence allowed the diffusion of speculation and misinformation to take place; these were neither corrected nor addressed, as the analysed PST case shows. In contrast, the blood bank used Twitter to mobilise blood donors to address an acute problem: a shortage of blood to treat casualties. The chapter concludes by offering recommendations to the authorities for future major incidents. Book edited by Harald Hornmoen and Klas Backholm.

This background note pertains to how far right extremist groups have coopted methods from the ‘cyber caliphate’ and jihadist Internet use to develop their own support networks. Specifically, the material deals with the varying levels of online presence, comparing jihadist and far right strategies to disseminate propaganda. By adhering to this layered network, the source reveals how extremist groups of all varieties are able to protect themselves while simultaneously projecting their message. The source also briefly touches on the few, but crucial divergences between the jihadist and far right methods.

OSCE’s background note on jihadist internet usage provides valuable context and a succinct survey of how the extensive research already done on jihadist internet presence also applies to the far right. Researchers looking to study the correlations between the two should begin here.
