What is MAL-2026-13803?

MAL-2026-13803 is a malicious package in dzcvhfruwluwe, published on 12 Aug 2026.

Official description

The package's sole shipped file is index.html, a fake 'Cloudflare Verifying…' page containing an obfuscator.io-style script that reconstructs the URL https://lo<…>ofte.live/ and calls window.location.replace on a 1-second timeout to redirect the viewer to that external.live domain. package.json declares no lifecycle scripts and main points at the HTML file, so neither npm install nor require() executes the payload against the installing developer. The harm is browser-side: end users who somehow load the HTML are redirected to an attacker-controlled destination. This is registry abuse hosting phishing/malvertising content 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.

What should I do about MAL-2026-13803?

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