Its callback runs concealed code that transfers current URL parameters to a hidden destination and redirects the browser. - **Trigger:** A user opens index.html and the Turnstile callback fires. - **Impact:** Potential phishing or leakage of URL-borne tokens to an undisclosed destination. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-08-14T04:19:51.097Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated query-parameter forwarding and browser redirect. - **Attack narrative:** The package is a browser page masquerading as a security-verification screen. Once its Turnstile callback runs, obfuscated JavaScript constructs a hidden URL, copies every parameter from the current page URL, and calls browser location replacement. This redirects the visitor while forwarding query data to an undisclosed endpoint. - **Rationale:** The concealed post-verification redirect and wholesale query forwarding are concrete browser-side attack behavior, not package-aligned functionality. It does not execute during npm installation, but the shipped main artifact is malicious when opened. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Obfuscated callback builds a destination URL, copies query parameters, and replaces the browser location., HTML presents a Cloudflare-style security-verification page and invokes the hidden callback after Turnstile events., Manifest ships only this HTML page as the package main, with no legitimate package functionality. - **Evidence against:** No npm lifecycle scripts or Node install-time execution are declared., No local file, environment, or child-process access is present. ## Public findings ### 1.
