azuredocs-ext-coinbasehelp[.]webflow[.]io

azuredocs-ext-coinbasehelp.webflow.io was observed hosting a page titled “Coinbase® Wallet® Extension® | Available on the Chrome Web …”. The page title explicitly references Coinbase, and the domain is listed as a brand‑impersonation infrastructure targeting the Coinbase brand. The site was served over HTTPS using a Google Trust Services certificate (WE1) and employed Cloudflare’s edge network with HTTP/3 enabled. DNS resolution returned the Cloudflare IP address 104.18.36.248, which belongs to ASN 13335 (Cloudflare, Inc.) and is geolocated in the United States. Nameservers journey.ns.cloudflare.com and lamar.ns.cloudflare.com confirm the use of Cloudflare’s DNS service.

The domain was registered through MarkMonitor, Inc., a registrar commonly associated with legitimate brand protection, on 08 May 2013. Despite the legitimate registrar, the domain’s reputation is extremely poor: Scamadviser assigns a trust score of 1 / 100, Google Safe Browsing flags it for social‑engineering, and VirusTotal recorded 15 detections out of 93 scanned scanners. The domain appears on one external security blocklist and has been taken down by the PhishDestroy takedown service; HTTP requests now return a 404 status, indicating the site is offline. Evidence confirms a crypto‑scam classification, but the specific payload or credential‑harvesting mechanism has not been publicly disclosed.

No additional indicators such as phishing email samples, malicious binaries, or command‑and‑control endpoints are available in the current intelligence set. Defenders should block any network traffic to 104.18.36.248 when associated with the host header azuredocs‑ext‑coinbasehelp.webflow.io, add the domain to URL filtering and email security policies, and monitor for similar Cloudflare‑hosted subdomains that reference Coinbase or other financial services.
