What it detects

This rule detects wscript.exe executing a script with an explicit vbscript engine selection and batch mode flag. Gamaredon GammaSteel launches its VBScript loader this way to suppress errors and dialogs during execution. Explicitly forcing the engine and silencing output is unusual for benign scripts and points to automated malware execution.
