The package's postinstall.js runs automatically on npm install and combines child_process.execSync with http/https.request and multiple curl invocations to collect host information (including reads of /etc/hosts) and POST/GET the results to a remote endpoint. The file uses a hardcoded hostname target, executes shell commands to gather system data, and transmits it over HTTP without any relation to the package's advertised data-transformation purpose. The package name mimics the n8n community-node naming convention, providing a lure for users seeking legitimate n8n utilities. Installing the package on default settings triggers immediate host reconnaissance and outbound exfiltration to an attacker-controlled destination.
