The npm postinstall hook executes postinstall.js, which uses child_process to spawn a Python reverse shell that connects to the hardcoded remote host 14.225.210.85:80 and dup2's a PTY-backed /bin/sh over the socket, giving the operator of that host an interactive shell on the installer's machine. Execution is gated by a hostname allowlist check (os.hostname() === 'ubuntu-fc-uvm'), a target-restriction technique that keeps the payload dormant on unintended hosts (scanners, sandboxes) and only detonates on the intended victim. The package presents itself as a Strapi plugin but ships no plugin functionality relevant to the postinstall behavior; the postinstall is the payload.
