Which versions of prezdentkxheiw are malicious?

The following npm versions of prezdentkxheiw are flagged malicious: 1.0.0, 1.0.1. Treat any of these as compromised.

How do I remediate prezdentkxheiw if I installed it?

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

I already installed prezdentkxheiw — how do I know if it already compromised me?

If prezdentkxheiw 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.

Advisory published Aug 12, 2026Updated Aug 12, 2026

prezdentkxheiw is a confirmed malicious npm package (MAL-2026-13833) that typosquats a legitimate package to trick installs (malicious versions 1.0.0, 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall prezdentkxheiw

What this malware does

The package contains only index.html (declared as main) and package.json. The HTML impersonates a Cloudflare 'Just a moment...' challenge and includes an obfuscator.io-style script whose onTurnstileComplete handler reconstructs a target URL from an encoded string array (_0x2885) and calls window.location.replace to redirect the browser. There are no preinstall/install/postinstall/prepare lifecycle hooks, no JavaScript entrypoint, and the declared main is an HTML file that Node cannot execute via require. Installing or requiring this package does not run code on the installer's machine. The artifact is abuse of the npm registry as static hosting for a phishing/redirect landing page aimed at browser visitors (e.g. via a CDN like unpkg), not a supply-chain attack against installers.

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.
