The destination is a hardcoded ngrok tunnel unrelated to any registry or vendor infrastructure, and the beacon fires automatically without any caller action or opt-in. The package's own metadata describes it as a `Dependency Confusion to RCE` proof-of-concept, and the install-time callback carries the installer's internal hostname to an external third party.\n",
