coinbaseprolgin[.]onepage[.]website

The domain coinbaseprolgin.onepage.website was observed on July 12, 2026 as an active brand-impersonation site targeting Coinbase users. The site returns an HTTP 302 redirect and presents the generic title “One page website for free – Online website builder”. No visual content has been captured, so the exact login or credential-stealing mechanisms remain unknown. The domain was registered on September 17, 2014 through Hosting Concepts B.V. d/b/a Registrar.eu and is hosted on a server located in the Netherlands (AS20857 Signet B.V.) with IP address 136.144.226.23. DNS is served by ns.compra.be, ns.compra.eu, ns.compra.nl, and ns.compra.uk. The SSL certificate is issued by Sectigo Limited under the Sectigo Public Server Authentication CA DV R36, indicating a valid‑looking TLS handshake. Reputation services flag the domain as malicious: VirusTotal reports ten out of ninety‑five scanners flagging it, Gridinsoft assigns a trust score of 0 / 100, and the site appears on a single security blocklist. PhishDestroy has already added the domain to its blocklist, and the overall risk rating is marked as high. The infrastructure uses Plesk, PHP, Bootstrap, Nginx, Sendgrid, Pingdom RUM, jQuery, and Google Analytics, a stack commonly observed in credential‑harvesting campaigns. Defenders should immediately block network resolution of coinbaseprolgin.onepage.website and any associated IP address 136.144.226.23 at perimeter firewalls and DNS filtering services. Security teams should monitor for outbound connections to the listed nameservers and for any email traffic that references the Sendgrid endpoints observed. Incident response teams should treat any credential submissions to Coinbase‑related services as potentially compromised and advise users to reset passwords and enable multi‑factor authentication.
