What it detects

This rule detects wscript.exe running a VBScript file located under C\Users\Public. Revenge RAT drops opera.vbs and index.vbs into the Public folder and executes them to launch its PowerShell stage. Script hosts running .vbs files from the world-writable Public directory are a common malware staging pattern.
