hainan[.]pilot45[.]com

This domain, hainan.pilot45.com, was observed hosting a generic phishing site. The page title returned by the HTTP response is "网站筹建中", indicating the site was under construction in Chinese. The domain was registered on 23 December 2024 through Gname.com Pte. Ltd. and resolves to the IP address 172.67.128.224, which belongs to Cloudflare, Inc. (AS13335) and is geolocated in the United States. No TLS certificate was presented, meaning connections are unencrypted.

Nameserver delegation points to aron.ns.cloudflare.com and titan.ns.cloudflare.com, consistent with the Cloudflare hosting. The domain appears on a single security blocklist and has been taken offline, with PhishDestroy reporting it as blocked. On VirusTotal, 15 of 95 scanners flagged the domain as malicious, reinforcing the phishing classification. The limited detection footprint suggests a short‑lived operation, but the presence of Cloudflare infrastructure indicates the operator leveraged a reputable CDN to hide origin.

Defenders should ensure that any outbound filtering or DNS sinkholing solutions block resolution of hainan.pilot45.com, add the IP 172.67.128.224 to deny lists, and monitor for newly registered domains that share the same registrar or nameserver pattern. Continuous re‑scanning of the IP range is advised, as Cloudflare hosts many unrelated services and future malicious payloads could appear on the same address block. Incident response teams should also verify that internal users have not accessed the site before it was taken down and should review logs for any credential submissions that may have been captured during the brief window of activity.
