AI Security Review

scanned 19d ago · by lpm-firewall-ai

The published HTML is a fake Cloudflare waiting page. When opened in a browser it loads Turnstile, posts JSON to a hidden endpoint, decrypts a destination URL with a bundled AES key, copies visitor query parameters onto that URL, and redirects.

Static reason

One or more suspicious static signals were detected.

Trigger

A user or site opens or serves index.html in a browser.

Impact

The visitor is forced through a fake security check and sent to an attacker-chosen site, which can deliver phishing or malware.

Mechanism

Obfuscated Cloudflare-challenge traffic redirector

Attack narrative

This package is not a library. It ships one HTML file that copies Cloudflare's Just a moment challenge, including Turnstile. Hidden obfuscated script rebuilds a host key and AES key, posts JSON after the challenge, decrypts the reply into a URL, attaches the current query string, and redirects the browser. That is a traffic-distribution lure, not a Cloudflare product.

AI rationale

Source shows a fake Cloudflare challenge page whose only job is to gate a fetch, AES-decrypt a destination, and redirect the browser. That is concrete malware behavior even though npm install does not auto-open the file.

Summary

Malicious code in luftmvfiwgxydes (npm)

Details

The package was found to contain malicious code or consuming dependency that contains malicious code ## Source: ghsa-malware (8cf9f25e87c3310292b60b507773f9689e59eeb6e950eb2e6a7c44b68deea04e) 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.

Decision evidence

public snapshot

AI called this Malicious at 90.0% confidence as Malware with low false-positive risk.

Evidence for block

The package is a random-named npm artifact whose only published file and main entry is index.html, with no library API or metadata.
index.html impersonates a Cloudflare Just a moment challenge and loads Turnstile from challenges.cloudflare.com.
The inline script is packed with javascript-obfuscator and rebuilds a hidden hostKey, AES key, and Turnstile site key.
After the challenge it POSTs JSON via fetch, AES-decrypts the response into a URL, copies visitor query parameters, and redirects with location.replace.

Evidence against

package.json has no preinstall, install, or postinstall scripts, so npm install does not open the page by itself.
The decrypted redirect host is not present in plaintext after static inspection.
