SystemadminBd, also stylized as SYSTEMADMINBD or System Admin BD, is a Bangladeshi hacktivist group that first emerged in April 2023. The group's primary motivation is rooted in nationalist and ideological beliefs, framing their actions as retaliation against perceived insults to Bangladesh, media bias, or geopolitical adversaries such as India and Israel. They explicitly position themselves as "Muslim BlackHats & Cyber Resistance Fighters" committed to exposing corruption, injustice, and misinformation. What distinguishes SystemadminBd is their consistent focus on website defacements, data leaks, and distributed denial-of-service (DDoS) attacks to achieve their goals, often accompanied by public messages expressing their grievances against specific targets.
