Violent extremist organisations (VEOs) use social media platforms to promote extremist content and coordinate agendas. The use of digital platforms to disseminate information and coordinate activities by VEOs in Nigeria has grown considerably in recent years. This report analyses the adoption of social media before and after attacks by Boko Haram, Islamic State of West Africa Province (ISWAP) and Ansaru. In the post‐attack environment, Boko Haram, ISWAP and Ansaru use platforms to claim responsibility and display their strengths against the state’s security forces. By demonstrating their capacity to attack state security forces, the three groups aim to erode the public’s confidence in the state military’s capacity to safeguard national security.
