Malicious package

khanbmnxlsnpm

Advisory published Updated

khanbmnxls is a confirmed malicious npm package (MAL-2026-13820) that typosquats a legitimate package to trick installs (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in khanbmnxls (npm)

MAL-2026-13820
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall khanbmnxls

What this malware does

The package contains a single index.html that impersonates a Cloudflare Turnstile 'Just a moment...' challenge page. The inline JavaScript is heavily obfuscated (obfuscator.io-style _0xNNNN identifiers and a shuffled string array) and assembles a redirect URL beginning with https://kh from decoded string fragments, wired to a fake data-sitekey and an onTurnstileComplete callback. The package declares no npm lifecycle scripts (no preinstall/install/postinstall/prepare), no JavaScript main, and no bin entry, so npm install and require() of this package do not execute the HTML or its embedded script. The harm surface is limited to a browser that renders the file directly; developers installing the package from npm are not attacked at install or import time. The artifact is a phishing/redirect lure hosted on the npm registry rather than a functional Node 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.

Detection & response playbook

Typosquat
  1. Find it

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

  2. If you installed it — respond

    khanbmnxls is a typosquat — you almost certainly intended a legitimately-named package. Remove khanbmnxls, 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 khanbmnxls 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
