It can disclose the page's query parameters to a remotely supplied destination. - **Trigger:** A browser opens index.html and the Turnstile callback runs. - **Impact:** URL parameters may be sent to an attacker-controlled destination, enabling phishing or data disclosure. - **Evidence paths:** index.html, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-01T09:10:01.077Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote fetch, decryption, query forwarding, and browser redirect. - **Attack narrative:** The page presents a verification screen, then its callback uses obfuscated code to fetch a remote value, decrypt a destination URL, append the current page's query parameters, and replace the browser location. The destination is hidden from source review, so the package can route visitors and their URL-carried data to an operator-selected site. - **Rationale:** This is a concealed, remotely controlled redirect and query-forwarding mechanism, not a legitimate npm package function. It has no install hook, but its runtime behavior is concrete malicious data-routing behavior. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The HTML callback contains heavily obfuscated code that fetches a remote response., The response is decoded and decrypted to obtain a destination., The code copies current URL parameters to that destination and replaces the browser location., The manifest exposes this HTML file as the package entry point. - **Evidence against:** No npm lifecycle scripts are declared., No local file writes or shell execution are present. ## Public findings ### 1. High: Obfuscated Payload Loader - **Category:** Source - **Confidence:** 86.0% - **Path:** index.html - **Public source:** [View source]() Source contains an obfuscated payload loader that reconstructs and executes hidden code.
