- **Type:** Malicious package

## What is MAL-2026-13817?

MAL-2026-13817 is a malicious package in jhkxcixudnvm1, published on 12 Aug 2026. 

### Official description

The package contains only package.json and index.html, with index.html declared as `main`. The HTML imitates a Cloudflare 'Just a moment...' verification interstitial and includes an obfuscated script that, after a short timeout, reconstructs a destination URL from a shuffled string array and redirects window.location to it, forwarding all current query parameters. No JavaScript executes at `npm install` time and `require('jhkxcixudnvm1')` does not run the redirect (the entry is HTML, not JS), so this version does not attack installers or build systems directly. The concern is registry abuse: npm is being used to host a Cloudflare-impersonating phishing/redirect page that would harm end-users if the tarball's index.html were fetched and opened in a browser (e.g., via a CDN that serves package contents). Recommend human review for a registry-abuse takedown rather than a supply-chain block, since installing or requiring the package produces no code execution, data exfiltration, or credential access on the installer.

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-2026-13817?

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