en-coinbasepro-sso[.]created[.]app

The domain en-coinbasepro-sso.created.app was registered on July 12, 2023 through Tucows Domains Inc. and resolves to the IP address 216.150.16.193, which is announced by Amazon.com, Inc. (AS16509) and geolocated to the United States. DNS resolution is provided by Vercel’s authoritative servers ns1.vercel-dns.com and ns2.vercel-dns.com. The site presented a TLS certificate issued by Let’s Encrypt (R13) and enforces HTTP Strict Transport Security, indicating a deliberately configured HTTPS endpoint. An HTTP request to the root returned a 404 status, while the page title reported by scanners is "Sign In | Coinbase®", confirming a direct reference to the Coinbase brand.

Technical fingerprints include Google Cloud, Vercel, LaunchDarkly, Google Cloud CDN, and HSTS. The domain is listed on a single security blocklist and has been explicitly blocked by PhishDestroy. Google Safe Browsing classifies the site as a social‑engineering threat, and VirusTotal recorded 14 detections out of 95 scanned security vendors, reinforcing the malicious assessment.

The overall risk rating is high, and the current operational status is offline. Defenders should continue to block the domain at network perimeter devices, update URL filtering and threat‑intelligence feeds with the observed indicators, and monitor for any derivative sub‑domains that might reuse the same hosting infrastructure or certificate. Investigation of related Vercel‑hosted assets and the underlying Amazon AS16509 range can help identify additional malicious payloads that may be deployed using similar configurations.
