In August 2019, FireEye released the “Double Dragon” report on our newest graduated threat group, APT41. A China-nexus dual espionage and financially-focused group, APT41 targets industries such as gaming, healthcare, high-tech, higher education, telecommunications, and travel services. APT41 is known to adapt quickly to changes and detections within victim environments, often recompiling malware within hours of incident responder activity. In multiple situations, we also identified APT41 utilizing recently-disclosed vulnerabilities, often weaponzing and exploiting within a matter of days.
