Sylhet Gang is a hacktivist threat group that has appeared in multiple regional conflict-driven cyber campaigns. It has been identified among pro-Pakistan or anti-India hacktivist clusters active during the 2025 India-Pakistan crisis, where it publicly claimed disruptive operations against Indian government, defense, and critical-infrastructure-related organizations. Claimed targets in that campaign included Indian defense and state institutions, and the group was associated primarily with high-visibility operations such as distributed denial-of-service attacks, website defacements, phishing activity, and unverified breach claims that served propaganda and psychological-impact objectives more than covert persistence. Sylhet Gang has also been named among pro-Iranian or state-aligned hacktivist ecosystems active during the 2025-2026 Israel-Iran and broader Middle East escalation. In that context, it was associated with disruptive operations targeting government services, critical infrastructure, and financial institutions in Israel and several Gulf states hosting U.S. military assets. Reporting on this activity places the group within a broader coalition of Telegram-amplified hacktivist actors that coordinate claims, boost one another’s messaging, and participate in retaliatory cyber campaigns tied to geopolitical events. Available reporting supports characterization of Sylhet Gang as a politically aligned hacktivist actor focused on disruptive and influence-oriented cyber operations rather than a clearly documented advanced persistent threat. Its observed tradecraft is most consistently linked to DDoS activity, public attack claims, phishing, and other forms of initial-access or nuisance-level disruption in support of regional political causes.
