webmail[.]assets-coinbase[.]locker

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.
