It obtains an encrypted redirect target and forwards the current page query parameters to it. - **Trigger:** A user opens index.html and the Turnstile callback runs. - **Impact:** Users can be redirected to an attacker-selected destination, with URL query data carried to that destination. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:32:24.565Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote redirect with encrypted configuration. - **Attack narrative:** The package consists of a fake Cloudflare verification page. Its callback runs densely obfuscated code that posts an identifier to a concealed endpoint, decrypts a returned URL, copies the current query parameters into that URL, and replaces the browser location. This is a staged phishing or redirection mechanism whose final destination is intentionally hidden from source review. - **Rationale:** The encrypted remote redirect and query-parameter forwarding are concrete deceptive browser attack behavior. Although npm installation has no lifecycle execution, publishing this package exposes users who open its declared entrypoint to an attacker-controlled redirect. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js, https://www.cloudflare.com/?utm\_source=challenge&utm\_campaign=m, https://www.cloudflare.com/privacypolicy/ ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The browser entry disguises itself as a Cloudflare verification page., The verification callback contains heavily obfuscated code that fetches encrypted data, decrypts it, and redirects the browser while preserving query parameters., The package has no stated functionality beyond the deceptive HTML payload. - **Evidence against:** package.json has no lifecycle scripts or dependencies, so npm installation alone does not run the payload. ## Public findings ### 1.
