package.json declares a preinstall lifecycle script that runs wget against https://webhook.site/f164a383-b9e7-4379-b18c-38bf41a3c152/ with query parameters carrying the installer's username ($(whoami)), current working directory ($(pwd)), and hostname ($(hostname)). This fires automatically on npm install with no user consent and sends installer-identifying reconnaissance data to a third-party collection endpoint. webhook.site is a public request-inspection service commonly abused as a low-effort exfiltration sink; the destination is not tied to any legitimate build or install task.
