What it detects
This rule flags executions of dotnet-dump where the image is dotnet-dump.exe and the command line includes the collect flag. Attackers can use process dump tooling to capture memory from running processes, which may expose sensitive data. The detection relies on Windows process creation telemetry including the executable filename and command-line arguments.

- Process dumping is the expected behavior of the tool. So false positives are expected in legitimate usage. The PID/Process Name of the process being dumped needs to be investigated
