## Source: kam193 (f98f9dd8cd5b70474786eb054bccf9de05d98face434e0a814123e51c090f364) 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.
