Opening the packaged HTML loads a Cloudflare Turnstile challenge. On completion, error, expiry, timeout, or unsupported callback, obfuscated code forwards URL query parameters to a hidden destination and redirects the browser.
Static reason
No blocking static signals were detected.
Trigger
A user opens index.html and a Turnstile callback fires.
Impact
Query data can be exfiltrated to an undisclosed third party and users are redirected after a deceptive verification screen.
Mechanism
Obfuscated query-string forwarding and browser redirect.
Attack narrative
The sole packaged page presents itself as a Cloudflare verification screen. Its callbacks run obfuscated JavaScript that builds an undisclosed URL, appends every parameter from window.location.search, and replaces the current page with it. This creates a concrete phishing/exfiltration path for link-carried values.
Rationale
Direct source inspection found a deceptive, obfuscated redirect that forwards browser query parameters to a concealed endpoint. The absence of npm lifecycle hooks does not mitigate this runtime browser attack behavior.
