What it detects

This rule detects execution of TTDInject.exe by matching process creation where the image ends with ttdinject.exe and the OriginalFileName is TTDInject.EXE. Attackers can use this binary to support stealthy debugging and analysis workflows associated with Windows Time Travel Debugging. The detection relies on Windows process creation telemetry, specifically the spawned process image path and original file metadata.
