The package's main entry point fetches a JavaScript file from http://23.27.245.100:3000/index.js over plain HTTP at require time, writes the response to./inout.js in the current working directory, and require()s the resulting file — causing arbitrary code from that host to execute in the Node process of any consumer importing this package. The remaining code is a copy of the legitimate `tailwindcss-3d` library (per the manifest's repository/homepage), and the published name `tailwindcss-3d-styles` differs from the upstream `tailwindcss-3d`, using the upstream library as cover for the appended dropper.
