What it detects

This rule identifies Windows process creation where dotnet-trace.exe is launched with command-line content consistent with spawning a child process, indicated by the presence of '-- ' and 'collect'. Attackers may use this execution pattern to proxy or run additional payloads while blending into legitimate .NET diagnostic tooling. The detection relies on process creation telemetry including the executable image name and the full command line.
