# MAL-2026-15554: Malicious code in eth-pino (npm)


- **Type:** Malicious package
- **Package:** `eth-pino` (npm)
- **Published:** 29 Aug 2026

## What is MAL-2026-15554?

MAL-2026-15554 is a malicious package in eth-pino, published on 29 Aug 2026. 

### Official description

On require, lib/initializeCaller.js runs a top-level async IIFE that decodes a base64-obfuscated URL to https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df and POSTs a shallow copy of process.env to that endpoint with an x-secret-header header. The HTTP response body is then passed to new Function('require', response.data) and invoked with the real require, granting the remote operator arbitrary code execution in the installer's Node.js process. The destination URL is stored as a base64 literal to evade static URL scanners. The package name and file layout mimic the legitimate pino logger while the exported middleware is a no-op, consistent with typosquat delivery.

## What should I do about MAL-2026-15554?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
