What it detects

This rule flags process executions of winget.exe where the command line includes the actions to add a source and specifically uses an http:// URL. Adding an insecure download source can enable tampering or man-in-the-middle scenarios if packages are fetched over plaintext transport. Telemetry required includes Windows process creation events with command-line arguments and process image/original file name for winget.exe.
