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 published file is a fake Cloudflare challenge page. Opening it in a browser loads Turnstile, then obfuscated script fetches a remote payload, decrypts it with AES-CTR, and executes it with Function before following a server redirect. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-18T23:53:29.218Z - **Finished:** 2026-09-18T23:57:26.526Z - **Download time:** 502 ms - **Static scan time:** 51 ms - **AI review time:** 236754 ms - **Total time:** 237308 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 published file is a fake Cloudflare challenge page. Opening it in a browser loads Turnstile, then obfuscated script fetches a remote payload, decrypts it with AES-CTR, and executes it with Function before following a server redirect. - **Trigger:** A user or host site opens index.html in a browser (the package main entry). - **Impact:** Arbitrary JavaScript runs in the visitor browser, then the visitor is sent to an attacker-chosen URL. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-18T23:57:26.526Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Fake Cloudflare interstitial with obfuscated remote decrypt-and-Function loader - **Attack narrative:** This tarball is a browser lure, not a library. Opening index.html shows a Cloudflare Just a moment page and a Turnstile widget. After the check, obfuscated code posts a host key to an API whose hostname starts with https://ap, AES-CTR decrypts the reply with an embedded key, and runs that plaintext through Function. It then follows a server redirect\_url while copying the original query string. The random package name and missing product surface match a hidden payload loader, not a legitimate Cloudflare integration. - **Rationale:** Source is a fake Cloudflare challenge whose obfuscated script fetches, AES-CTR decrypts, and Function-executes a remote payload, then redirects the visitor. That is a concrete browser remote-code chain, so the package should be blocked even though npm install itself does not run it. - **Network endpoints:** https://challenges.cloudflare.com, https://challenges.cloudflare.com/turnstile/v0/api.js, https://ap ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest publishes only a random-named package whose main file is index.html and defines no npm lifecycle scripts., index.html impersonates a Cloudflare Just a moment page and loads the real Turnstile script from challenges.cloudflare.com., Obfuscated startup code reconstructs hostKey, aesKeyBase64, and a Turnstile site key at runtime., The page POSTs JSON containing hostKey to a hostname built from the literal https://ap prefix plus hidden fragments., The reply is AES-CTR decrypted with the embedded key and executed through the Function constructor., The loader then follows a remote redirect\_url and copies the visitor query string into that flow. - **Evidence against:** There are no preinstall, install, or postinstall hooks, so npm install does not run this page by itself., The tarball has no Node require, child\_process, or filesystem harvesting. ## Affected versions and remediation This report applies to luftmvfiwgxydes@1.0.3. - Avoid installing luftmvfiwgxydes@1.0.3. 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.
