Malicious package

hlksdcixycvfnpm

Advisory published Updated

hlksdcixycvf is a confirmed malicious npm package (MAL-2026-13814) that executes malicious code on install (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in hlksdcixycvf (npm)

MAL-2026-13814
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall hlksdcixycvf

What this malware does

The tarball contains a single file, index.html, declared as the package main. The HTML renders a Cloudflare Turnstile-themed 'verification' page containing obfuscator.io-style JavaScript that, on Turnstile callback, reconstructs a target URL and calls window.location.replace to redirect the browser. package.json declares no preinstall/install/postinstall/prepare lifecycle scripts, and npm cannot require an HTML main, so installing or importing this package performs no code execution on a developer machine. The obfuscated redirect only fires if a human opens index.html in a browser and completes the Turnstile widget; the target audience is browser visitors, not npm installers. The package appears to be abuse of the npm registry as static hosting for an obfuscated redirector / likely phishing landing page rather than 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.

Detection & response playbook

Malicious package
  1. Find it

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

  2. If you installed it — respond

    Remove hlksdcixycvf from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If hlksdcixycvf 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

No. hlksdcixycvf on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks hlksdcixycvf-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
