Executive Summary
Unit 42 researchers have identified multiple cyberespionage clusters conducting targeted attacks against a Southeast Asian government organization. The threat actors are deploying custom malware including USBFect, along with RATs and loaders, suggesting sophisticated and persistent intrusion capabilities. This campaign appears focused on long-term intelligence collection, potentially compromising sensitive government data and communications. Organizations should implement robust USB device controls, network monitoring for unusual C2 traffic, and maintain updated endpoint detection solutions to identify these custom malware variants.
