## What is MAL-2026-13838?

MAL-2026-13838 is a malicious package in unitel4, published on 12 Aug 2026. 

### Official description

Package contains only package.json and index.html, with main pointing at index.html. The HTML impersonates a Cloudflare 'Just a moment...' interstitial; its Turnstile callback runs obfuscated JavaScript that constructs a URL ending in a '.club/' domain, appends the current query string, and calls window.location.replace to redirect the browser. There are no preinstall/install/postinstall/prepare lifecycle hooks, and an HTML file cannot be executed via require()/import, so installing or loading this package in a Node.js build environment does not execute the redirect. The payload only fires when the HTML is served to and rendered by an end-user browser, indicating registry abuse to host a phishing/cloaking landing page rather than a supply-chain attack against developers who install the package.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-13838?

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