What it detects
This rule detects a Run registry key persistence entry whose value invokes WScript, the persistence mechanism used by the PhantomVAI loader to re-launch its script stage at logon. Registering a script host under Run ensures the loader survives reboots. Detecting this write surfaces persistent infostealer staging on the host.
