MAL-2026-13832 Malicious code in passport811 (npm)

[email protected] contains a single HTML file that impersonates a Cloudflare Turnstile 'Just a moment…' challenge. After the Turnstile callback fires, obfuscated JavaScript assembles a redirect URL to the Microsoft typosquat host microsofte.live (host string built at runtime from an obfuscator.io string-array lookup concatenated with the fragments 'ypt.micros' and 'ofte.live/') and calls window.location.replace() to send the browser there, forwarding the current query string. The package has no library or CLI surface and no lifecycle scripts — the HTML is not executed by npm install or by require(). The artifact is a hosted phishing kit distributed via the npm registry rather than code that attacks the machine performing the install.

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.
