Digitalisation of the activities of Islamic State in Iraq and Syria (ISIS) has been a longstanding issue in Southeast Asia. In recent years, the nature of this threat has become more widespread and complex. In countries like Indonesia, where radicalisation is primarily offline, online platforms still play a role in spreading extremist ideas and maintaining ideological networks. The phenomenon of online radicalisation can erode social cohesion, highlighting the need for strategic measures to counter its destabilising impact.

Indonesia has made several attempts to combat online radicalisation. The National Counter Terrorism Agency of Indonesia (BNPT) initiated the Duta Damai Dunia Maya campaign to counter harmful content on the Internet. Other online initiatives, such as BincangSyariah and Islamidotco, have also been promoting Islamic literacy, moderating religious interpretations, and correcting misleading narratives.

Nevertheless, Indonesia still encounters online radicalisation cases. In July 2024, Indonesia’s elite counterterrorism unit, Densus 88, detained a 19-year-old student who had expressed allegiance to ISIS through social media and was believed to be planning attacks on religious sites before he was caught.

The swift progress of Artificial Intelligence (AI), especially in areas of machine learning (ML) and natural language processing (NLP), presents both opportunities and challenges in combating online radicalisation in Indonesia. AI, generally defined as machines mimicking human intelligence, enables systems to recognise patterns, analyse content, and produce outputs in text, images, and videos. Within this AI landscape, ML allows models to enhance themselves through data, while NLP, as a specific ML application, deals with understanding and generating human language. These advancements provide possibilities for creating early detection systems, content moderation tools, and sentiment analysis tools that can spot and counter extremist messages online.

For the research, the author conducted interviews with fifteen experts across different fields, including law enforcement officers, academics, representatives from civil society organisations (CSOs), and employees of AI start-ups in Indonesia. The qualitative data collected from this process have been analysed through thematic analysis, and the preliminary findings reveal that AI can indeed complement the conventional CVE (countering violent extremism) methods in the country, albeit not without challenges

The increasing involvement of women in terrorism challenges traditional perceptions and necessitates a shift in counterterrorism strategies. Recent cases in Singapore illustrate how women are radicalised through online propaganda, familial influence, and ideological indoctrination, leading to their participation in extremist activities. Addressing this evolving threat demands gender-sensitive prevention and rehabilitation efforts, community engagement, digital counterterrorism, and tailored intervention programmes to counter radicalisation at its roots. COMMENTARY The recent detention of a 15-year-old self-radicalised female student in Singapore highlights the growing vulnerability of young individuals, especially women, to extremist influences online. Her case, the first involving a female minor under the Internal Security Act (ISA), signals an alarming shift in radicalisation trends, where even adolescents are being drawn to violent ideologies. This underscores the urgency of addressing radicalisation at its early stages, particularly in digital spaces where extremist propaganda thrives. Just months earlier, the case of a 56-year-old radicalised housewife demonstrated that women are no longer confined to passive roles in extremist networks. These developments challenge traditional assumptions about gender and radicalisation, reinforcing the need for targeted intervention efforts across different demographic groups.

In many cases, women were often involved as facilitators of terrorism, providing logistical support, acting as recruiters, or serving as symbols of ideological purity. However, recent trends show a growing number of women assuming leadership roles, engaging in combat, and even carrying out suicide attacks. Several factors drive this shift, including ideological indoctrination, social and economic disenfranchisement, and extremist organisations' strategic exploitation of gender norms. Terrorist groups such as ISIS, Boko Haram, and Al-Qaeda have actively sought to recruit women, recognising their potential to evade security measures and access targets that male operatives might struggle to reach. Extremist groups have used women as suicide bombers, assassins, and enforcers of their doctrine. In some instances, they have also taken on prominent roles in radicalisation efforts, using online platforms to spread extremist propaganda and recruit new members.

How does the internet affect the radicalisation of extreme-right lone actor terrorists? In the absence of an established theoretical model, this article identifies six mechanisms seen as particularly relevant for explaining online radicalisation. Having first reviewed a larger set of relevant lone actor terrorists, the study traces the mechanisms in three selected cases where the internet was reportedly used extensively during radicalisation. The findingsshow that the internet primarily facilitated radicalisation through information provision, as well as amplifying group polarisation and legitimising extreme ideology and violence through echoing.In all three cases, radicalisation was also affected considerably byoffline push-factors that through their presence made extreme online messages more impactful. The results challenge the view that offline interaction is necessary for radicalisation to occur but also the view that online influence itself is sufficient
