FIN10

Also known asFIN10

FIN10 is a threat actor tracked as FIN10. In the provided content, FIN10 is associated with use of PowerShell and Windows command shell activity for execution, persistence, lateral movement, discovery, and cleanup. Reported behaviors include executing malicious .bat files containing PowerShell commands; using PowerShell Empire for persistence; adding a Run key via the Registry option in PowerShell Empire; establishing persistence through S4U tasks and the Scheduled Task option in PowerShell Empire; using Meterpreter to enumerate users on remote systems; moving laterally via RDP; relying on publicly available software to gain footholds and establish persistence; and using batch scripts and scheduled tasks to delete critical system files. The content also explicitly maps FIN10 to PowerShell execution, Windows Command Shell execution, and exploitation/installation-related ATT&CK-style annotations.

Cobalt StrikeDetects the PowerShell pattern used at the end of a Cobalt Strike PowerShell loader to perform the decompression of the executable. This loader is used in attacks such as scripted web delivery. Cobalt Strike is a legitimate, commercial penetration testing tool that has been largely co-opted by ransomware gangs to launch attacks. Cobalt Strike's popularity is mainly due to its beacons or payload being stealthy, and easily customizable. Cobalt Strike Beacon provides encrypted communication with the C&C server to send information and receive commands.1May 6, 2026

CVE-2025-9491Microsoft Windows LNK File UI Misrepresentation Remote Code Execution VulnerabilityIn the wildEvidence2

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.
