Any Turnstile callback triggers an obfuscated, server-directed redirect to a decrypted destination. - **Trigger:** A browser opens index.html and a Turnstile success, error, expiry, timeout, or unsupported callback occurs. - **Impact:** Directs users to an attacker-controlled hidden destination, enabling staged phishing or payload delivery. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-08-24T03:11:16.411Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote-response decryption and browser redirect - **Attack narrative:** The package is a browser page disguised as Cloudflare verification. Its callback sends a hidden host key to an obfuscated endpoint, decrypts the response into a URL, preserves the current query parameters, and navigates the browser there. This conceals the final destination from static inspection and is a concrete staged redirect chain. - **Rationale:** The package contains no npm lifecycle hook, but its sole shipped entry is an intentionally obfuscated server-directed redirector behind a fake verification UI. The concealed remote destination creates a concrete malicious delivery surface. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Obfuscated handler runs after every Turnstile callback., Handler sends a generated host key with fetch to a hidden endpoint., It Base64-decodes and decrypts the server response into a URL., It redirects the browser to that decrypted URL and copies query parameters. - **Evidence against:** package.json has no lifecycle scripts or dependencies., The payload activates only when this HTML is opened and the challenge callback fires. ## Public findings ### 1.
