coibase-org[.]wstd[.]io

The domain coibase-org.wstd.io was registered through NameCheap, Inc. on February 21, 2026. DNS resolution points to the IP address 104.19.164.34, which is owned by AS13335 Cloudflare, Inc. and geolocated in the United States. The authoritative nameservers are sandra.ns.cloudflare.com and cosmin.ns.cloudflare.com, indicating that the site is front‑ended by Cloudflare’s edge network. A TLS certificate issued by Let’s Encrypt (identifier E8) is present, confirming the use of a publicly trusted certificate.

Automated fingerprinting detected Cloudflare services, a basic web stack, and support for HTTP/3. An HTTP request to the site returned a 403 status code, and the page title observed was "Coinbase Pro Login | Trade & Earn with Advanced Trade," directly referencing the Coinbase brand. The threat classification is brand impersonation targeting Coinbase users. Google Safe Browsing has flagged the domain for social engineering, and VirusTotal reports that 2 of 93 security vendors have flagged the host as malicious.

The domain appears on a single external blocklist (PhishDestroy) and is currently listed as offline, preventing live content analysis. While the observed indicators confirm a credential‑stealing infrastructure aimed at Coinbase, the exact page content and any payloads remain unverified due to the offline status. Defenders should immediately block the domain and its resolved IP at the network perimeter, add the domain to DNS sinkhole lists, and update intrusion‑detection signatures to reflect the observed page title and HTTP/3 fingerprint. Continuous monitoring of new subdomains registered with the same registrar or hosted on the same Cloudflare edge nodes is recommended, as threat actors often recycle similar infrastructure.
