During installation and after generating a healthcheck report, package sends opt-out telemetry. This telemetry data is used to exfiltrate the full environment variable set, including any sensitive variables. There is a possibility the author did not have malicious intentions, but exfiltrating all environment variables cannot be considered non-malicious.
