coinbase-extenton[.]created[.]app

On July 24, 2026 analysts observed that coinbase-extenton.created.app is currently offline but exhibits multiple indicators of a high‑risk brand‑impersonation campaign targeting Coinbase users. The domain was created on July 12, 2023 and registered through Tucows Domains Inc. DNS resolution points to IP address 216.150.16.193, which belongs to AS16509 Amazon.com, Inc., confirming that the site is hosted on Amazon infrastructure. The server presents a Let's Encrypt R13 certificate and advertises HSTS, indicating an attempt to convey legitimacy. Technically the site is built on the Vercel platform, as reflected by the nameservers ns1.vercel-dns.com and ns2.vercel-dns.com.

An HTTP request returns a 404 status code, and the only visible page title is "Coinbase Wallet Extension - Your Gateway to Web3," directly referencing Coinbase and reinforcing the impersonation intent. Google Safe Browsing flags the domain for social engineering, and VirusTotal records 11 detections out of 95 scanned security vendors, corroborating malicious classification. The domain appears on a single security blocklist and is actively blocked by PhishDestroy. While the site is offline, the available evidence—registration timing, hosting details, SSL configuration, page title, and multiple independent detections—strongly suggests a crypto‑scam operation designed to lure Coinbase users.

Uncertainty remains regarding the exact payload or credential‑harvesting mechanisms, as no live content is reachable for deeper inspection. Defenders should immediately add the domain and its resolving IP to blocklists, enforce DNS‑level filtering, and monitor for any future re‑hosting attempts. Continuous scanning of the IP range and Vercel DNS zones is advisable, as the infrastructure could be reused for similar impersonation campaigns.
