GDLockerSec is a ransomware group that first emerged in January 2025, primarily motivated by financial gain through data encryption and theft. The group employs a dual approach involving ransomware to lock victim systems and an infostealer component to exfiltrate sensitive data, thereby implementing a double extortion strategy. Operations indicate a global focus, targeting diverse sectors such as public administration, education, and technology across countries including Hong Kong, Nigeria, Morocco, and the United States.
