In 2024, ESET identified a new China-aligned APT group named LongNosedGoblin, which targets governmental entities in Southeast Asia and Japan. The group employs a custom toolset, primarily using C#/.NET applications, to conduct cyberespionage. Key tools include NosyDoor, a backdoor utilizing Microsoft OneDrive for command and control, and NosyHistorian, which collects browser history to inform further attacks. Concurrently, Talos reported on UAT-8302, another China-nexus APT group, which uses similar tactics and tools, including the malware NetDraft, also known as NosyDoor. Both groups are linked through their use of advanced malware and tactics for credential extraction and network proliferation. The campaigns indicate a coordinated effort to maintain long-term access to sensitive government systems. The ongoing threat remains significant, with multiple victims affected across different regions.
