Opening the HTML entrypoint presents a Turnstile page that activates an obfuscated remote redirect flow. The final destination is supplied encrypted by a server.

Static reason

One or more suspicious static signals were detected.

Trigger

A user opens or renders index.html and a Turnstile callback fires.

Impact

Users can be silently sent to an attacker-controlled destination, with the current query parameters copied to it.

Mechanism

Obfuscated remote response decryption followed by browser redirect.

Attack narrative

The package disguises its sole entrypoint as a Cloudflare verification page. Any configured Turnstile outcome invokes the same obfuscated handler. That handler posts to a concealed endpoint, decrypts a server response into a URL, copies the current page parameters, and redirects the browser. The remote destination is deliberately concealed, making this a server-controlled phishing or payload-delivery redirect.

AI rationale

This is an obfuscated, remotely controlled redirect hidden behind a verification page, not a legitimate npm package function. Although it has no install hook, opening its declared entrypoint activates concrete malicious browser behavior.

Advisory

The package's only shipped file is an HTML page that mimics a Cloudflare 'Just a moment...' verification screen and embeds obfuscator.io-style JavaScript (`_0xNNNN` identifiers, string-array lookups) that runtime-constructs a URL beginning with 'https://ap' from decoded string-array entries. The package.json declares no preinstall/install/postinstall lifecycle scripts, and `main` points at an HTML file that Node cannot require, so installing or requiring the package does not execute the embedded script on the installer's machine. The content is a phishing page targeting browser users who might be steered to render it, i.e. registry abuse using npm as a content host rather than an attack on package installers. ## Source: ghsa-malware (ee9b178308f2fb0e66b25444c0b033ae9057d8bf3b1d186c54e748edb4f5bf6f) 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.
