Storm-1133 is a Gaza-based threat actor first observed in early 2023, tracked by Microsoft, that operates to further the geopolitical interests of Hamas, the de facto governing authority of the Gaza Strip. This group is distinguished by its use of sophisticated social engineering tactics, including masquerading as Israeli human resources managers or project coordinators on LinkedIn, to gain initial access and conduct reconnaissance. Their primary objective is cyber espionage, focusing on intelligence collection from targets perceived as hostile to Hamas, and maintaining persistent access through dynamically updated command-and-control infrastructure.
