Its callback retrieves and decrypts a concealed redirect target, then navigates the browser while preserving URL parameters. - **Trigger:** A user opens index.html and the Turnstile callback runs. - **Impact:** The package can send a user to an attacker-controlled destination hidden from static inspection, including with forwarded query parameters. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-04T03:56:07.141Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload retrieval, AES decryption, and browser redirection. - **Attack narrative:** The HTML imitates a Cloudflare verification page. Every Turnstile completion-related callback enters heavily obfuscated code that contacts an undisclosed endpoint, decrypts its response, appends the current page query parameters, and redirects the browser. The encrypted response keeps the final destination outside the published package, making this a concealed remote redirect loader. - **Rationale:** The package is a disguised browser redirect loader rather than a usable npm library. Its obfuscation, remotely supplied encrypted destination, and challenge-gated automatic navigation establish concrete malicious behavior. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package entry point is an HTML page that runs when opened., Completing or failing the displayed Turnstile challenge invokes a large obfuscated callback., That callback fetches an opaque remote response, decrypts it with Web Crypto, forwards the current query parameters, and navigates the browser to the decrypted URL. - **Evidence against:** package.json contains no npm lifecycle scripts., The inspected source shows no local file access or child-process execution. ## Public findings ### 1.
