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.
An estimated time describes an observation window. It does not prove a registrar action or the exact moment a site became unavailable.

How do phishing scams typically work?
가짜 웹사이트 — 도메인을 약간만 변경한, 정식 사이트와 픽셀 단위로 완벽하게 일치하는 복제 사이트
pig butchering — Telegram·왓츠앱·데이트 앱을 통해 몇 주에 걸쳐 신뢰를 쌓은 뒤, 돈을 훔쳐갔다
회복 사기 — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
AI를 이용한 사기 — 딥페이크, 자동화된 피싱, AI로 생성된 사이트 등으로 인해 사기 행각을 적발하기가 더 어려워지고 있다
앞으로 어떻게 하면 스스로를 지킬 수 있을까요?
