coine-base-prolog[.]pages[.]dev

The domain coine-base-prolog.pages.dev was created on 21 February 2026 and is hosted on Cloudflare’s network (AS13335, United States). DNS resolution returns the IPv6 address 2606:4700:310c::ac42:2d1e and the authoritative name servers are augustus.ns.cloudflare.com and rafe.ns.cloudflare.com, indicating the domain is fully provisioned through Cloudflare, Inc. The site presents the page title “Suspected phishing site | Cloudflare” and returns HTTP 403, which suggests that the content is being blocked by Cloudflare’s protective rules. The SSL certificate is issued by Google Trust Services under the WE1 designation, confirming the use of a valid TLS certificate. Security telemetry flags the domain as a high‑risk generic phishing campaign employing brand impersonation.

VirusTotal reports 11 of 95 scanners flagging the domain, and Google Safe Browsing classifies it as social‑engineering. The site appears on one public blocklist and has a Gridinsoft trust score of 0 / 100. PhishDestroy has already added the domain to its blocklist, and the current operational status is offline. Analysis indicates that the threat actor leveraged Cloudflare’s free hosting to hide malicious infrastructure while presenting a generic phishing warning page.

No additional payloads, redirects, or malicious scripts have been observed in the available data, leaving the exact phishing vector and targeted brand undefined. Defenders should continue to block the domain at the DNS and proxy layers, monitor for any resurgence of the same host name or associated IP ranges, and incorporate the 11‑vendor detection signature into intrusion‑detection rules. Ongoing observation of Cloudflare‑hosted IPv6 space for similar patterns is recommended, as is periodic re‑scanning of the domain should it become active again.
