chrome-coinbase-extensionn[.]created[.]app

The domain chrome-coinbase-extensionn.created.app was observed as part of a brand‑impersonation campaign targeting Coinbase users. The domain was registered on 12 July 2023 through Tucows Domains Inc. and resolves to the Amazon‑owned IP address 216.150.1.65 (AS16509, United States). DNS resolution is handled by Vercel’s authoritative name servers ns1.vercel-dns.com and ns2.vercel-dns.com, and the site is served over a Let’s Encrypt R13 certificate that includes HSTS. An HTTP request returns a 404 status, indicating that the content is no longer publicly reachable; the current operational status is listed as offline.

Google Safe Browsing classifies the URL as social engineering, and the domain appears on a single security blocklist, where it was blocked by PhishDestroy. VirusTotal analysis shows eight of ninety‑five scanners flag the domain, confirming the presence of malicious indicators. The page title advertised as “Coinbase Chrome Extension | Connect to Web3 & DeFi Apps” aligns with the reported scam type of a crypto‑related fraud, and the domain explicitly impersonates the Coinbase brand.

While the infrastructure details are concrete, the exact payload or phishing page content has not been captured, leaving the specific credential‑capture mechanisms unknown. Defenders should add the domain to blocklists, monitor DNS queries for the resolved IP, and enforce strict TLS inspection for traffic to Vercel‑hosted subdomains. Continuous observation of any resurgence of the site is advised, as the underlying hosting platform could be reused for future impersonation attempts.
