MAL-2026-16191 Malicious code in strapi-plugin-uicc-meeb (npm)

postinstall.js is registered as both the npm postinstall hook and the package main. On install it polls os.hostname() every 3 seconds and, when the hostname matches the hardcoded value 'ubuntu-fc-uvm', spawns 'bash -i' with stdio bound to /dev/tcp/14.225.210.85/80, yielding an interactive reverse shell on the installer's host to the operator of that endpoint. A long setTimeout keeps the Node process alive indefinitely after the postinstall phase, and setInterval retries the connection, providing persistence and targeted activation. The package name imitates a Strapi plugin but its shipped code performs no plugin functionality.
