Package is presented as a Tailwind CSS utility, but its default export getPlugin fetches JSON from a hardcoded bare-IP endpoint (https://31.97.137.157:45000/icons/109) and passes the returned data.credits field to new Function(...) bound with require, process, module, and Buffer, then invokes it. Following the README's instruction to register the default export as a Tailwind plugin causes Tailwind to invoke getPlugin, executing attacker-controlled JavaScript with full Node.js capabilities on the developer's machine. Cover-story framing (variables named IconProvider/iconDomain, a CDN hostname map for cloudflare/fastly/akamai/cloudfront, a /ajax/libs/font-awesome/... path fragment, a bearrtoken: "logo" header, and an unused setDefaultModule decoy) masks the loader as icon retrieval. Declared runtime dependencies (@primno/dpapi, better-sqlite3, node-machine-id) are consistent with browser-credential and cookie-stealer payloads that the fetched code can deploy.
