What this malware does

Published as part of a ClickFix-style fake-CAPTCHA phishing campaign documented by OX Security (see reference). The package's only file is index.html, declared as the npm "main" entry; package.json defines no preinstall/install/postinstall/prepare lifecycle script, so the payload does not execute at npm install time. index.html renders a fake Cloudflare Turnstile verification widget. An obfuscator.io-obfuscated inline script builds a hardcoded redirect URL to https://login.microsofte.live/ (a typosquat of a Microsoft sign-in domain), appends the visitor's original query-string parameters, and navigates the browser there via window.location.replace(). The package therefore does not attack the installing machine directly; it is used as a static file host on the npm CDN (e.g. unpkg/jsDelivr) so the index.html can be linked to and opened directly in a victim's browser as a phishing/ClickFix landing page. Published by npm user "johnvaldez9a" as part of a burst of near-identical single-purpose packages published between 2026-08-04 and 2026-08-24 that share this same fake-Turnstile-redirect page structure.

The package was found to contain malicious code or consuming dependency that contains malicious code

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.

Detection & response playbook

Typosquat
  1. Find it

    Search your lockfiles and build artifacts for ndmxchdjxn2 (version 1.0.0).

  2. If you installed it — respond

    ndmxchdjxn2 is a typosquat — you almost certainly intended a legitimately-named package. Remove ndmxchdjxn2, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

  3. Did it already run?

    If ndmxchdjxn2 was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions
