It is well established that jihadist groups and their supporters post URLs on online platforms to outlink to items of propaganda stored on other platforms. Industry initiatives – such as Global Internet Forum to Counter Terrorism’s inclusion of URLs in its hash-sharing database, and Tech Against Terrorism’s Terrorist Content Analytics Platform – have sought to counter this practice. These measures, together with new regulatory regimes (e.g. the EU’s Terrorist Content Online Regulation) and the growing use of decentralised services, raise the question whether jihadist groups’ propaganda dissemination strategies are perhaps being forced to evolve. This report considers whether there is evidence of such an evolution, by examining the means that three jihadist groups (Islamic State (IS), Al-Qaeda (AQ) and Al-Shabaab) used to disseminate their propaganda during a two-month period in early 2023.

This report presents the main theories and ways radical groups influence and attract individuals online, and the most common tools and strategies governments use to counter its impact.

The prevalence of dangerous misinformation and extreme views online has intensified since the onset of Israel-Hamas war on 7 October 2023. Social media platforms have long grappled with the challenge of providing effective mitigation schemes that can scale to the 5 billion-strong online population. Here, we introduce a novel solution grounded in online network engineering and demonstrate its potential through small pilot studies. We begin by outlining the characteristics of the online social network infrastructure that have rendered previous approaches to mitigating extremes ineffective. We then present our new online engineering scheme and explain how it circumvents these issues. The efficacy of this scheme is demonstrated through a pilot empirical study, which reveals that automatically assembling groups of users online with diverse opinions, guided by a map of the online social media infrastructure, and facilitating their anonymous interactions, can lead to a softening of extreme views. We then employ computer simulations to explore the potential for implementing this scheme online at scale and in an automated manner, without necessitating the contentious removal of specific communities, imposing censorship, relying on preventative messaging, or requiring consensus within the online groups. These pilot studies provide preliminary insights into the effectiveness and feasibility of this approach in online social media settings.

In 2012, the National Institute of Justice’s (NIJ) Domestic Radicalization to Terrorism program began funding research on issues related to domestic radicalization and terrorism in the United States. NIJ-sponsored research has addressed a variety of factors that can play a role in both facilitating and preventing domestic radicalization, including social networks. This report synthesizes findings from that research, focusing on the role that peer relationships and social dynamics can play as either a gateway to or a gatekeeper preventing radicalization in the United States.

The purpose of this report is to provide a comprehensive overview of existing knowledge on contemporary extremist narratives circulating online in three countries across Europe; Austria, Bulgaria and Sweden. To achieve this, the report draws on a review of an extensive body of previous research and secondary data sources, pursuing two primary objectives: firstly, it maps what kind of extremist narratives are on offer across Europe today, and second, it identifies where across the digital mainstream, these are currently in circulation.

Despite the ongoing need for practitioners to identify violent extremists online before their engagement in violence offline, little is empirically known about their digital footprints generally or differences in their posting behaviors compared to their non-violent counterparts particularly – especially on high-frequency posting days. Content analysis was used to examine postings from a unique sample of violent and non-violent right-wing extremists as well as from a sample of postings within a sub-forum of the largest white supremacy forum during peak and non-peak posting days for comparison purposes. Several noteworthy posting behaviors were identified that may assist in identifying credible threats online.
