coinbase-extension-webpage[.]created[.]app

This domain, coinbase-extension-webpage.created.app, is flagged as a high-risk crypto scam impersonating Coinbase. Infrastructure analysis reveals the domain was registered on July 12, 2023, through Tucows Domains Inc. and is currently offline, returning an HTTP 404 status. The page title, 'HomePage™ | Coinbase Extension™ Secure Your Account With Coinbase,' explicitly targets the Coinbase brand, aligning with the scam type classified in available intelligence. The domain resolves to IP 216.150.1.129, hosted on Amazon.com, Inc. (AS16509) in the US, and uses nameservers ns1.vercel-dns.com and ns2.vercel-dns.com, indicating Vercel hosting technology.

SSL certification is provided by Let's Encrypt (R13), and HSTS is detected on the domain. Detection data shows 10 of 95 security vendors on VirusTotal flagged this domain, while Google Safe Browsing classifies it as social engineering. It appears on one security blocklist and is blocked by PhishDestroy. The domain's current offline status suggests takedown action, though defenders should verify whether residual DNS records or cached content remain accessible.

No evidence of active redirection or associated malware distribution is present in the available data, but the domain's historical use for crypto scams warrants continued monitoring. Defenders are advised to block the domain at the DNS and proxy levels, review logs for prior connections, and alert users who may have interacted with it before takedown. The exact content served during its active period is not yet analysed, but the combination of brand impersonation, scam classification, and detection flags confirms its malicious intent.
