What it detects

This rule identifies remote thread creation events where the target process ends with rundll32.exe and the initiating process ends with wabmig.exe, wab.exe, or ImagingDevices.exe. Remote thread injection is commonly used to run code in another process while hiding activity from straightforward process monitoring. The detection relies on process image path suffixes for the source and target in Windows remote thread creation telemetry.
