(AS16509) in the United States. The TLS certificate presented is issued by Google Trust Services under the WR1 intermediate, indicating a valid certificate chain for the Vercel hosting platform. An HTTP request returns status code 451 and the page title “Deployment Unavailable,” confirming that the site is currently taken offline. VirusTotal analysis shows that 13 of 93 scanning engines flagged the domain, suggesting malicious characteristics.

The domain appears on a single external blocklist and is actively blocked by the PhishDestroy service, reinforcing its classification as a generic phishing threat. Detected technologies include Vercel and enforced HTTP Strict Transport Security (HSTS). Because the site is offline, direct inspection of payloads or credential‑stealing pages is not possible, leaving the exact phishing vector undefined. Analysts should continue to monitor the resolver IP for any re‑activation and ensure that the IP address 216.198.79.67 is denied in perimeter firewalls and proxy filters.

Adding casefb139049-zv39.vercel.app to DNS‑based blocklists and to endpoint URL filtering policies will reduce exposure. Organizations using Vercel should audit newly created subdomains for similar patterns and enforce strict validation of TLS certificates. Regular re‑scanning with multi‑engine services is advised to capture any changes in detection scores. Given the elevated risk rating, traffic to this host should be treated as malicious until the domain is fully retired.
