## What is MAL-2026-13810?

MAL-2026-13810 is a malicious package in gdwkh6vcbu, published on 12 Aug 2026. 

### Official description

Package gdwkh6vcbu@1.0.0 ships a single index.html declared as `main`, with no JavaScript entry point, no install lifecycle hooks, and placeholder-only metadata (random 10-character name, no description/author/repository/license, files list containing only index.html). The HTML impersonates a Cloudflare Turnstile 'Just a moment...' verification page. On Turnstile completion, obfuscator.io-style code (string-array + _0x2637 base64 decoder) constructs a URL whose host ends in 'loud.homes/', propagates the current page's query parameters to that URL, and calls window.location.assign to redirect the visitor. The package is not usable as a Node module; its sole purpose is to be served over npm-backed CDN mirrors (unpkg/jsdelivr) as a phishing landing/redirector page. `npm install` does not execute code on the installing developer, but the artifact abuses the npm namespace/CDN to host and distribute obfuscated phishing content targeting end-user browsers.

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-2026-13810?

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