Loading threat actor…
APT41 is a China-linked threat actor associated with both state-directed espionage and financially motivated cyber activity, and is widely tracked under aliases including Barium, Winnti, Wicked Panda, Wicked Spider, Double Dragon, Brass Typhoon, Blackfly, Bronze Atlas, Bronze University, Grayfly, Red Kelpie, Red Typhoon, Leopard Typhoon, Heart Typhoon, Earth Baku, and Amoeba. The group is commonly discussed within the broader Winnti umbrella and has also been linked in reporting to Chinese contractor ecosystems including i-SOON and Chengdu 404. Public reporting and U.S. indictments have tied APT41 to operations conducted on behalf of the Ministry of State Security, reinforcing its status as a China-nexus espionage actor.

This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
