The domain resolves to IP address 104.21.4.20, which belongs to AS13335 Cloudflare, Inc. and is geolocated in the United States. DNS resolution uses the Cloudflare‑provided authoritative nameservers alec.ns.cloudflare.com and mckenzie.ns.cloudflare.com, and the TLS certificate presented is issued by Google Trust Services under the WE1 designation. Automated reconnaissance identified the use of Cloudflare services, confirming the hosting infrastructure. The site presented a page title of “Suspected phishing site | Cloudflare”, indicating a deliberate attempt to impersonate Cloudflare.

According to the threat taxonomy, the campaign is classified as brand impersonation targeting Cloudflare. The domain is currently offline, and its risk rating is elevated. Reputation scoring from Gridinsoft assigns a trust score of 45 out of 100, reflecting moderate suspicion. The domain appears on a single security blocklist and has been actively blocked by the PhishDestroy filtering service. VirusTotal analysis shows that one of ninety‑three scanned security vendors flagged the domain, providing a minimal but non‑zero detection signal.

No additional public intelligence such as OTX indicators or Safe Browsing entries were observed. The limited detection footprint suggests that the infrastructure may be short‑lived or that the campaign has not yet achieved broad distribution. Defenders should incorporate the domain into blocklists, monitor the associated IP range AS13335 for any resurgence, and enforce TLS inspection policies to capture any future payloads that might use the same certificate chain. Continuous observation of the registrar Web Commerce Communications Limited for new registrations resembling bestcas.vip is recommended, as is periodic re‑query of VirusTotal and other multi‑engine scanners to detect any change in detection counts.
