Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The browser fetches and runs attacker-controlled code after the challenge, which can redirect, steal data, or drop further malware. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 1.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-16398 identifies this version as malicious. 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 the published HTML page runs an obfuscated Cloudflare-lookalike challenge that posts a host key to a hidden https://ap endpoint, decrypts the response with a baked-in AES key, and executes it 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:** 2026-09-18T23:56:47.067Z - **Download time:** 511 ms - **Static scan time:** 40 ms - **AI review time:** 197292 ms - **Total time:** 197844 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 the published HTML page runs an obfuscated Cloudflare-lookalike challenge that posts a host key to a hidden https://ap endpoint, decrypts the response with a baked-in AES key, and executes it through Function. - **Trigger:** A user or host opens index.html in a browser (the package main file). - **Impact:** The browser fetches and runs attacker-controlled code after the challenge, which can redirect, steal data, or drop further malware. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-18T23:56:47.067Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated captcha-gated remote payload loader - **Attack narrative:** This package ships a fake Cloudflare waiting page as its only published file. When someone opens index.html, obfuscated script rebuilds a hidden API URL starting with https://ap, posts a host key, imports an AES key, decrypts the response, and runs it with the Function constructor. That is a remote code loader behind a Turnstile gate, not a normal npm library. - **Rationale:** Source shows a random-named HTML dropper that impersonates Cloudflare, contacts a reconstructed API, decrypts the reply, and executes it with Function. That is a concrete browser remote-code chain, so the package should be blocked even though npm install itself does not run the page. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com, https://challenges.cloudflare.com/turnstile/v0/api.js, https://ap ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The published package is a random-named HTML-only artifact whose main file is index.html, with no library API or description., The page impersonates Cloudflare's Just a moment challenge and loads Turnstile from challenges.cloudflare.com., Packed string-table code hides the real logic behind an obfuscated IIFE., Reconstructed strings are passed to the Function constructor so hidden JavaScript can run in the page., The script POSTs a hostKey object to a reconstructed URL that starts with https://ap., A base64 AES key is imported with crypto.subtle.importKey and used on the remote response before execution. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts, so npm install does not open the page., The package does not use Node child\_process or filesystem APIs. ## Affected versions and remediation This report applies to luftmvfiwgxydes@1.0.0. - Avoid installing luftmvfiwgxydes@1.0.0. 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.
