SigmaHQ Detections@sigmaHQ

•updated Oct 9, 2025•0•20

Detects the loading of 'Amsi.dll' by specific Living Off the Land Binaries (LOLBINs) such as ExtExport.exe, odbcconf.exe, and rundll32.exe. This activity can indicate an attempt to bypass Antimalware Scan Interface (AMSI) protections, often associated with 'PowerShell without PowerShell' attacks where malicious scripts are executed without directly invoking powershell.exe.
