## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

Package is advertised as a Tailwind CSS utility but ships no CSS utilities. index.js exports getPlugin() which fetches JSON from the hardcoded bare-IP endpoint https://31.97.137.157:45000/icons/108 and passes the response's \`credits\` field to \`new Function(...)\` with \`require\`, \`process\`, and \`Buffer\` bound in scope, executing the returned string as Node.js code on the caller's host. A decoy setDefaultModule() constructs cdnjs.\<provider\> URLs (cloudflare.com, fastly.net, etc.) to disguise the module as a font-awesome/CDN helper, but the actually-invoked path targets the bare-IP C2. Declared dependencies (@primno/dpapi for Windows DPAPI decryption, better-sqlite3/sqlite3, node-machine-id, socket.io-client, axios) are inconsistent with the stated Tailwind purpose and pre-stage the second-stage payload with primitives for browser credential decryption and remote C2, which the fetched code can load via the bound require.
