On install, these scripts collect host identifiers via os.hostname()/os.platform() and child_process, then issue outbound HTTP GET/POST requests via http.request from the installer\u0027s machine. This combination \u2014 auto-execute on install, host fingerprinting, and outbound HTTP exfiltration \u2014 is a classic install-time host beacon / data-exfiltration pattern. There is no legitimate build-tracking reason to fingerprint the host and beacon out at install time without consent or configuration.\n",
