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.

In this paper, 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 analyse 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 fora longer period. Information flows from antisemitic agents on Twitter gained less traction, while information flows emanating from capable and willing counter-speech actors -i.e. Jewish organisations- 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 organisations 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 organisations in reducing the propagation of cyberhate and increasing trust in SM platforms.

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.

The Syrian conflict led to a resurrection of ISIS in terms of recruitment, financing, propaganda, and enlisting itself as an actor in the Middle East. ISIS’s ability to use both social media and other traditional methods of recruitment requires countries like Turkey to adopt multi-faceted approaches in order to be more effective. Cyberspace, and particularly social media, is very critical to understanding how ISIS sustains its recruitment and propaganda activities.

This report entitled ‘ISIS in Cyberspace: Findings from Social Media Research’ focuses on social media and terrorism by analyzing how pro-ISIS Twitter users see and legitimize ISIS and its ideology in cyberspace. Following an extensive review of literature on ISIS’s historical background along with its capabilities in various fields, the research analyzes tweeting patterns of sampled pro-ISIS Twitter accounts and examines the contents of messages posted by those accounts.

The “Islamic State in Iraq and Syria” (ISIS) is the main source of instability, not only in Iraq and Syria, but also throughout the Middle East. The instability poses a danger for the other parts of the world because of the influx of foreign fighters to the region. Extremists have taken advantage of the continuing conflicts in Iraq and Syria, with Syria in particular serving as a magnet for thousands of foreign fighters from more than 90 countries. While most of these ISIS combatants are men, many women have left their countries behind to join the “caliphate” and support its cause. Social media have played a key role in luring women to join ISIS. This study therefore analyzed the ISIS organization’s social media propaganda and grass-roots recruitment activities aimed at women in Turkey. The results of the analysis provide important information about the strategies that ISIS uses to spread its ideology.
