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. The only shipped file is a fake Cloudflare Turnstile interstitial. Opening it runs obfuscated script that contacts a reconstructed API, decrypts the response with AES-CTR, and turns that into a navigation URL. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-19T00:52:36.521Z - **Finished:** 2026-09-19T00:56:05.567Z - **Download time:** 513 ms - **Static scan time:** 46 ms - **AI review time:** 208486 ms - **Total time:** 209046 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:** The only shipped file is a fake Cloudflare Turnstile interstitial. Opening it runs obfuscated script that contacts a reconstructed API, decrypts the response with AES-CTR, and turns that into a navigation URL. - **Trigger:** A user opens index.html in a browser or completes the Turnstile widget. - **Impact:** The visitor is sent to an attacker-chosen URL after a forged Cloudflare check; query parameters are folded into that request. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-19T00:56:05.567Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated fake-CAPTCHA loader with remote AES-CTR decrypt and redirect - **Attack narrative:** This package is not a library. It ships one HTML page that impersonates Cloudflare bot-check UI, loads real Turnstile, then runs a heavily obfuscated script. That script holds a campaign hostKey and AES key, injects the challenge layout, posts the hostKey to a hostname built from a https://ap prefix, decrypts the body with AES-CTR, and converts the plaintext into a URL used after the widget completes. The random package name and hidden C2 fit a traffic-distribution landing page, not a published web component. - **Rationale:** Source is a complete fake Cloudflare challenge that hides a remote fetch, AES-CTR decrypt, and URL redirect behind obfuscation. That is a working browser malware loader even though npm install itself does not run it. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com, https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Manifest is a random-looking name with no scripts or dependencies and publishes only index.html as main., index.html clones a Cloudflare Just a moment Turnstile page and loads challenges.cloudflare.com., A javascript-obfuscator IIFE hides hostKey, an AES key, and challenge HTML, then injects that layout., After Turnstile, the script POSTs hostKey to a reconstructed https://ap endpoint, AES-CTR decrypts the reply, and builds a redirect URL. - **Evidence against:** package.json has no preinstall, install, or postinstall hooks, so npm install does not open the page., Node require of main would not execute HTML as JavaScript. ## Affected versions and remediation This report applies to luftmvfiwgxydes@1.0.5. - Avoid installing luftmvfiwgxydes@1.0.5. 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.
