The domain webmail.assets-coinbase.locker was identified as a brand impersonation threat targeting Coinbase users. This phishing domain used a fake Roundcube Webmail login page to steal credentials. No drainer kit was detected, but the page title "Roundcube Webmail :: Welcome to Roundcube Webmail" indicates an attempt to harvest email and possibly cryptocurrency account access.
Technical indicators for this domain include a VirusTotal detection score of 12 out of 95 security vendors flagging it as malicious. The domain was registered through Dynadot LLC on October 24, 2025, and resolved to IP address 104.21.43.188. It appeared on one security blocklist and had no SSL certificate, further confirming its fraudulent nature. Google Safe Browsing status was not explicitly provided, but the domain's offline status suggests it was blocked.
As of the latest check, this domain has been taken offline, mitigating immediate risk. However, users who may have interacted with it should change their Coinbase and email passwords immediately and enable two-factor authentication. PhishDestroy recommends monitoring accounts for unauthorized activity and reporting any suspicious emails to Coinbase's security team. The remaining risk is low due to the domain being offline, but similar domains may appear in the future.

For the registrable domain assets-coinbase.locker behind this subdomain, the registrar above operates under an ICANN accreditation agreement. The links below provide the official fee schedule and current DNS abuse compliance guidance.
Accreditation is a contract, not a safety certification.
RAA §3.18 establishes abuse-contact and handling requirements. This report can document stored outbound notices and later technical observations; it does not by itself establish receipt, investigation, remediation, or contractual non-compliance.

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.
This timeline displays historical security and status checkpoints observed by the PhishDestroy automated monitoring network. It records domain lifecycle updates, scanner changes, and threat telemetry over time.
12 recorded events. These records describe collected evidence, outgoing notifications and publication; they do not confirm a complete investigation or a takedown.

A stored Cloudflare Radar report is available. The report link alone is not a malicious verdict and does not prove that every network field was captured.
The latest stored checks indicate that the reported content is unavailable; this does not establish who or what caused the change.
