What it detects

This rule flags remote thread creation events where the source image ends with '\\ttdinject.exe'. Using Ttdinject.exe as a proxy for remote thread injection can enable stealthy code execution in another process. It relies on Windows telemetry that records remote thread creation with the originating executable name.
