coibase-pro-eng[.]pages[.]dev

The domain coibase-pro-eng.pages.dev was registered on February 21, 2026 through Cloudflare, Inc. and is hosted on Cloudflare’s network (AS13335) with the IP address 188.114.96.3 located in the United States. The site presents a Cloudflare‑issued SSL certificate (Google Trust Services / WE1) and employs HSTS and HTTP/3, indicating a modern CDN configuration. Nameserver records point to mary.ns.cloudflare.com and aaron.ns.cloudflare.com, confirming the use of Cloudflare’s DNS services. HTTP requests return a 403 status code and the page title displayed by the service is "Suspected phishing site | Cloudflare," which aligns with the brand‑impersonation intent targeting Coinbase.

The domain is classified as a crypto‑related scam and appears on a single security blocklist; PhishDestroy has already taken it offline. VirusTotal analysis shows that 11 of 95 scanning engines flag the domain as malicious, reinforcing the suspicion of fraudulent activity. Gridinsoft assigns a trust score of 0 out of 100, indicating a high likelihood of abuse.

While the infrastructure details are concrete, the exact content served before takedown remains unverified, and no additional threat‑intel feeds (OTX, Safe Browsing) are cited. Defenders should continue to block the domain at perimeter and DNS layers, monitor the associated IP range for any re‑use, and update endpoint protection signatures with the VirusTotal detection set. Ongoing observation of Cloudflare‑registered domains that mimic Coinbase is advised, as the rapid provisioning and takedown cycle suggests a transient phishing campaign.
