package.json declares postinstall: node postinstall.js, which unconditionally spawns bash with stdio redirected to /dev/tcp/14.225.210.85/443, giving the remote endpoint interactive command execution as the installing user on every npm install. The script includes a reconnect loop that re-establishes the shell on disconnect, providing persistence for the duration of the process. No user action, configuration, or runtime invocation is required for the callback to fire.
