MAL-2026-13818 Malicious code in jkbnwsdf8 (npm)

The package contains a single file, index.html, declared as the package main. The HTML is styled as a Cloudflare Turnstile 'Just a moment…' challenge page and contains obfuscator.io-encoded JavaScript that, after a Turnstile callback, constructs a redirect URL from a fragmented literal ('https://lo' + <decoded> + /) and calls window.location.assign(targetUrl), forwarding the caller's query string. There is no package.json lifecycle script (no preinstall/install/postinstall/prepare) and no JavaScript main entry, so npm install and require() of this package do not execute any code on the installer's machine — Node cannot execute HTML. The redirect only fires against browser end-users who load the HTML through an npm CDN such as unpkg or jsdelivr, which is outside the installer-protection scope of this engine. The package is abusing npm as a static-hosting CDN for what appears to be a redirect/cloaking page and warrants a registry-abuse takedown, but it does not attack developers or build systems that install it.

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.
