What it detects

This rule identifies when a PowerShell process (powershell.exe or pwsh.exe) creates a remote thread in another process. Remote thread creation is a common technique for executing code within the context of a separate process, which can help attackers evade detection and persist execution. It relies on Windows telemetry that records remote thread creation events and includes the calling process image and parent image (notably excluding CompatTelRunner.exe).
