What it detects

This rule detects registry values written under a CurrentVersion key that carry VBScript or scripting-object keywords such as Execute, Shell.Application or CreateObject. Adversaries including Nobelium via the Sibot malware hide executable script inside registry values to evade file-based detection and later run it through a script interpreter or rundll32. Storing script logic in registry data is unusual for legitimate software and indicates fileless staging.
