# MAL-2026-4529: Malicious code in cloudpivot (npm)

## What is MAL-2026-4529?

MAL-2026-4529 is a malicious package in cloudpivot, published on 23 May 2026. 

### Official description

On `npm install`, the package.json preinstall hook runs `wget` against http://194.120.24.50:7374 with query parameters carrying `$(whoami)`, `$(pwd)`, `$(hostname)`, and a base64-encoded copy of `/etc/passwd`. The package ships no functional code — `main: index.js` is declared but no index.js is present — so the only effect of installing the package is the exfiltration probe firing automatically. The destination is a bare IP over plain HTTP, with no relation to any declared publisher, and the package description itself references Burp Collaborator abuse. Any developer or CI system that runs `npm install cloudpivot` leaks host identifiers and the local user database to the operator of 194.120.24.50.

## What should I do about MAL-2026-4529?

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