The package declares a postinstall lifecycle hook ("postinstall": "node postinstall.js") that executes on every `npm install`. postinstall.js invokes child_process.exec with a bash reverse-shell command connecting the installer's host to the hardcoded remote endpoint 14.225.210.85:80 via /dev/tcp, redirecting stdio to give the remote party an interactive shell on the installer's machine. Execution is gated by a hostname allowlist (matching 'ubuntu-fc-uvm'), and a retry loop plus a log file at /tmp/postinstall-revshell.log indicate a persistent, targeted deployment. The plugin name mimics the Strapi plugin namespace but ships no plugin functionality relevant to that framing.
