sihnup-coinbase-pro[.]created[.]app

Analysis of the domain sihnup-coinbase-pro.created.app indicates it was actively involved in a crypto scam impersonating Coinbase, a cryptocurrency exchange platform. The domain, registered through Tucows Domains Inc. on July 12, 2023, resolved to the IP address 216.150.1.65, hosted under AS16509 (Amazon.com, Inc.) in the United States. Its nameservers, ns1.vercel-dns.com and ns2.vercel-dns.com, suggest the use of Vercel's infrastructure, a detail corroborated by the detection of Vercel technologies on the site. The page title, 'Coinbase® Pro Login - Get Started With Coinbase®,' explicitly targets Coinbase users, aligning with the scam type categorized as a crypto scam.

The domain was flagged by one security blocklist and detected by 12 of 95 security vendors on VirusTotal, indicating moderate but not universal recognition of its malicious nature. It was blocked by PhishDestroy and is currently offline, returning an HTTP 404 status. The SSL certificate was issued by Let's Encrypt (R13), a common choice for both legitimate and malicious sites due to its accessibility. HSTS was also detected, which may have been employed to lend an appearance of legitimacy or to enforce encrypted connections.

Defenders should note that while the domain is offline, its infrastructure—particularly the use of Vercel and Amazon hosting—remains a potential vector for future campaigns. The registration age (three years as of the report date) and the use of a reputable registrar do not preclude malicious activity, as such domains can persist undetected for extended periods. Organizations are advised to monitor for similar patterns, such as Coinbase-branded subdomains under created.app or other Vercel-hosted properties, and to update blocklists accordingly. The exact content and functionality of the phishing page remain unanalyzed, but the available evidence confirms its intent to deceive users of the targeted brand.
