128711coinbase.com is an impersonation phishing site that pairs the Coinbase name with a meaningless numeric prefix to pass as an official exchange address. It targets Coinbase customers. PhishDestroy first flagged it on 2026-10-03. As of 2026-10-19 the site still responded, but DNS for its content had gone inactive, so the phishing page was not loading even though the domain remains live and could be reactivated.
How the scam works
Phishing pages of this kind copy the look of a Coinbase sign-in or account-verification screen. They capture the email, password and one-time 2FA codes a victim types in, then use them to log in to the real account and move funds out before the owner notices. The page's only visible title was "Please Wait," a generic loading message rather than Coinbase branding. We classified the site as Coinbase impersonation based on the brand-bearing domain name and the independent detections below.
Evidence
On 2026-10-06, 9 of 91 VirusTotal engines flagged the domain, including alphaMountain.ai, CRDF, Forcepoint ThreatSeeker, Fortinet, G-Data, Gridinsoft, LevelBlue and SOCRadar. That count is modest, but it comes from unrelated vendors that reached the same verdict. Spamhaus lists the domain in its DBL under the phishing category. It also appears on the MetaMask and SEAL blocklists alongside PhishDestroy's own, and it is referenced in two AlienVault OTX threat pulses.
Infrastructure
The domain was registered on 2026-09-30 through PDR Ltd. (PublicDomainRegistry.com) and was flagged just three days later. That short gap is typical of throwaway domains set up for a single campaign. Traffic runs through Cloudflare's network (AS13335, US), which hides the server that actually hosts the content. Its TLS certificate comes from Google Trust Services (WE1), so the browser padlock only shows an encrypted connection and says nothing about whether the site is genuine.
What to do
If you entered Coinbase credentials on this site, sign in to Coinbase directly and change your password right away. Reset 2FA, preferably to an authenticator app or security key, and review recent logins, devices and withdrawals. Contact Coinbase support at once if you see activity you don't recognize. Change the password anywhere else you reused it. Defenders should block the domain at DNS and proxy level, search mail and web logs for visits since 2026-09-30, and watch for similar Coinbase lookalikes that use numeric prefixes.

Availability, content, DNS and registration are independent evidence layers. NXDOMAIN, an unreachable origin or missing content alone does not prove registrar action. A registrar or provider is credited only when a direct technical marker identifies that actor. Report causality is shown separately.
