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 published page is a fake Cloudflare check. Hidden JavaScript fetches an encrypted remote payload with a host key, decrypts it with a baked-in AES key, and runs the result through Function. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-18T23:53:29.223Z - **Finished:** 2026-09-18T23:56:28.998Z - **Download time:** 514 ms - **Static scan time:** 38 ms - **AI review time:** 179222 ms - **Total time:** 179775 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 published page is a fake Cloudflare check. Hidden JavaScript fetches an encrypted remote payload with a host key, decrypts it with a baked-in AES key, and runs the result through Function. - **Trigger:** Opening or serving index.html in a web browser. npm install does not run it. - **Impact:** The victim browser runs attacker-controlled decrypted JavaScript after a fake security check. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-18T23:56:28.998Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated fetch, AES decrypt, and Function-based remote code execution behind a fake Cloudflare Turnstile page - **Attack narrative:** This package is not a library. It ships a Cloudflare-looking waiting page as its only file. When that page is opened, obfuscated script rebuilds a challenge UI, talks to a hidden endpoint with a host key, decrypts the reply with a hard-coded AES key, and executes the reconstructed code through Function. Turnstile completion then calls a hidden redirect hook. That is a browser remote-payload loader, not a legitimate npm module. - **Rationale:** Source shows a fake Cloudflare interstitial whose obfuscated script fetches, decrypts, and Function-executes a remote payload. Missing install hooks only means npm will not auto-open the page; the published artifact is still a concrete remote-code loader. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com, https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json publishes a random-looking name, sets main to index.html, and has no install scripts., index.html copies Cloudflare's Just a moment waiting page and loads the real Turnstile script., A large obfuscated inline script rebuilds hidden strings, a host key, and a fake challenge layout as soon as the page runs., That script posts the host key with fetch, decrypts the JSON reply with a baked-in AES key, and runs reconstructed JavaScript through Function., Completing Turnstile calls window.\_\_challengeRedirect, which the hidden loader defines. - **Evidence against:** There are no npm preinstall, install, or postinstall hooks, so a normal registry install does not open the HTML., The only plaintext network host is challenges.cloudflare.com; the fetch URL itself is obfuscated. ## Affected versions and remediation This report applies to luftmvfiwgxydes@1.0.2. - Avoid installing luftmvfiwgxydes@1.0.2. 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.
