coinbase[.]19ua8[.]com

The domain coinbase.19ua8.com was registered on 21 February 2026 and is presently taken offline. DNS resolution points exclusively to the IPv6 address 2a02:4780:1:466:0:27fd:482:4, which is advertised as belonging to Hostinger International Limited (AS47583) and geolocated to the United States. The site presented the HTTP response header with a page title of “Just a moment…”, indicating that the content was not captured before takedown. TLS negotiation uses a ZeroSSL RSA Domain Secure Site CA certificate, a free certificate often employed by short‑lived malicious infrastructure.

Static analysis on VirusTotal shows that 2 of 95 scanning engines flagged the domain, providing limited but notable detection across the vendor ecosystem. Gridinsoft assigned a trust score of 0 out of 100, suggesting an extremely low reputation. The domain appears on a single known security blocklist and has been actively blocked by the PhishDestroy feed, confirming that at least one defensive community has taken remediation action. Brand‑targeted impersonation is evident: the domain name incorporates the legitimate brand “coinbase”, and the supplied intelligence classifies the operation as a “Crypto Scam”.

No additional malicious payloads, redirection chains, or credential‑capture pages have been observed in the limited snapshot, leaving the exact attack vector uncertain. Defenders should continue to monitor the associated IPv6 address for any resurgence, enforce blocklist entries for the domain and its host ASN, and consider adding the certificate fingerprint to TLS inspection rules. Given the low trust score, vendor detections, and confirmed blocklist presence, the indicator should be treated as high‑confidence malicious.
