Leviathan, widely known as APT40, is a Chinese state-sponsored cyber-espionage threat actor. It is also tracked as BRONZE MOHAWK, FEVERDREAM, GADOLINIUM, Gingham Typhoon, Kryptonite Panda, MUDCARP, Red Ladon, TEMP.Jumper, and TEMP.Periscope. The group conducts targeted intrusion activity using spearphishing emails with malicious document attachments and impersonation domains to gain initial access and support targeting. It has used PowerShell, VBScript, and regsvr32 for execution; Background Intelligent Transfer Service jobs to transfer malicious files and establish persistence; Startup-folder shortcuts for persistence; and custom DLL loaders to decrypt and execute JavaScript backdoors. Leviathan has downloaded follow-on scripts and tools from attacker-controlled infrastructure, exfiltrated victim data through command-and-control channels, and used reflective DLL loading to execute backdoor functionality in memory. These tradecraft patterns are consistent with long-term intelligence collection operations.

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.
