Its opaque callback obtains and decrypts a remote redirect target. - **Trigger:** A visitor loads index.html and any Turnstile callback fires. - **Impact:** It can redirect a visitor to an attacker-selected destination while preserving current URL parameters. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-01T11:16:59.547Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Encrypted remote redirect loader - **Attack narrative:** The package is a browser page disguised as a Cloudflare verification screen. Completion and failure callbacks enter heavily obfuscated code that posts a hidden identifier, decrypts a server-provided value, appends the current query parameters, and replaces the browser location. This creates a concealed, remotely controlled redirect chain suitable for phishing or traffic delivery. - **Rationale:** The active, obfuscated remote redirect mechanism has no legitimate package purpose and hides its final destination. The absence of npm lifecycle hooks limits installation impact but does not neutralize the browser-delivered malicious 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 manifest exposes index.html as the package entry point., All challenge outcomes invoke the same opaque handler., That handler fetches encrypted remote data, decrypts a destination, copies URL parameters, and redirects the browser. - **Evidence against:** There are no npm lifecycle scripts or Node dependencies., No local file or shell operations are present. ## Public findings ### 1.
