Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Opening index.html in a browser shows a fake Cloudflare check, then the packed script posts a hidden host key and AES-decrypts a remote reply that supplies redirect\_url. npm install does not run this page, but the shipped file is a live command-and-control interstitial, not a library. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-19T00:52:36.524Z - **Finished:** 2026-09-19T01:00:05.661Z - **Download time:** 517 ms - **Static scan time:** 38 ms - **AI review time:** 448581 ms - **Total time:** 449137 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Opening index.html in a browser shows a fake Cloudflare check, then the packed script posts a hidden host key and AES-decrypts a remote reply that supplies redirect\_url. npm install does not run this page, but the shipped file is a live command-and-control interstitial, not a library. - **Trigger:** A user or site opens index.html in a web browser. - **Impact:** The visitor is sent to an attacker-chosen URL after the challenge, which can deliver phishing or further malware. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-19T01:00:05.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Fake Cloudflare Turnstile gate with obfuscated AES fetch and remote redirect - **Attack narrative:** This package is not a Node module. It publishes a fake Cloudflare Just a moment page. When that page is opened, packed JavaScript talks to a remote server with a hidden host key, decrypts the answer with a baked-in AES key, and follows redirect\_url after Turnstile. That is a traffic-distribution interstitial, not a legitimate challenge widget. - **Rationale:** Source shows a fake Cloudflare interstitial whose obfuscated script fetches, AES-decrypts, and follows a remote redirect\_url. That is concrete malware behavior even though npm install itself does not execute the HTML. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com ### Review decision - **Verdict:** Malicious - **Confidence:** 86.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package has a random name, ships only index.html as main, and is not a usable Node library., index.html impersonates a Cloudflare waiting page titled Just a moment and loads Turnstile from challenges.cloudflare.com., A packed inline script stores hostKey and aesKeyBase64, POSTs JSON with fetch, then AES-decrypts the reply with crypto.subtle., After the challenge, the script reads redirect\_url from that decrypted control data and onTurnstileComplete calls window.\_\_challengeRedirect., The same script uses the Function constructor and an encoded string table to hide those steps. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts, so npm install does not run the page., Requiring the HTML main in Node does not execute the browser script., The remote fetch host is built from obfuscated strings, so the exact command-and-control URL is not plaintext. ## Affected versions and remediation This report applies to luftmvfiwgxydes@1.0.4. - Avoid installing luftmvfiwgxydes@1.0.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
