Brotherhood Capung BCI is a hacktivist group observed as active in 2026. It has been listed alongside other contemporary hacktivist actors such as IT ARMY OF RUSSIA, BLAZER TEAM ATTACK, Lystic Team #ID, Legion Null, and NoName057(16). Available high-confidence reporting identifies the group as part of the broader hacktivist ecosystem but does not provide corroborated attribution to a specific state, country of origin, or formal organizational structure. Publicly supported details on its victimology, preferred sectors, and distinctive tooling remain limited. In the 2026 threat environment, hacktivist activity has commonly overlapped with disruptive operations such as network denial-of-service and, more broadly across the ecosystem, with data-leak promotion and financially adjacent cybercrime services; however, actor-specific operational details for Brotherhood Capung BCI are currently not available at high confidence.
