APT39 is an Iranian state-sponsored cyber-espionage threat actor, also tracked as Chafer, Remix Kitten, ITG07, Burgundy Sandstorm, and Cadelle. The group has targeted telecommunications and travel-sector organizations, with operations focused on intelligence collection, including against Israeli and Western organizations. APT39 has obtained initial access through spearphishing emails carrying malicious attachments. Its observed post-compromise tradecraft includes PowerShell execution, downloading tools and additional payloads, scheduled-task persistence, username and network-share discovery, screen capture, keylogging, file collection, and exfiltration through command-and-control communications. The group has also deleted deployed files, consistent with defense-evasion activity.

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.
