427334-coinbase.com was a phishing page that impersonated Coinbase behind the page title "Coinbase - Tickets", a fake customer-support ticket desk. It targeted Coinbase customers who were looking for help with their accounts, or who had been told they had an open case. PhishDestroy first flagged it on 2026-09-17. The site has been offline since 2026-09-19, and its DNS was still inactive when last checked on 2026-10-19.
How the scam works
Fake ticket portals depend on urgency. A victim receives a message about a security alert, a frozen balance or a pending case, and a numbered link sends them to a page that looks like Coinbase support. The page then asks them to "verify" their identity by entering their email, password and 2FA codes, and sometimes recovery phrases or ID documents. The numeric prefix in the domain suits this lure because it reads like a case reference. With those details, attackers can take over the account and move the funds out before the victim realises what has happened.
Evidence
Eight of 89 VirusTotal engines flagged the domain as of 2026-09-17: ChainPatrol, alphaMountain.ai, CRDF, Forcepoint ThreatSeeker, Fortinet, Google Safe Browsing, Gridinsoft and Kaspersky. That count is modest, but the vendors include both crypto-focused and mainstream security engines. Google Safe Browsing classed it as social engineering. urlscan.io returned a malicious verdict and detected Coinbase branding. Spamhaus lists it in its DBL as phishing, it appears on the MetaMask, SEAL and PhishDestroy blocklists, and four AlienVault OTX pulses reference it.
Infrastructure
The domain was registered through OwnRegistrar, Inc. on 2026-09-16 and was being flagged a day later. It went dark within three days of registration, which fits a disposable domain built for a short campaign. Traffic ran through Cloudflare, with the resolving address geolocated to Canada. Because Cloudflare's network sits in front of the site, the real origin server stays hidden.
What to do
If you typed your Coinbase credentials into this page, change your password immediately and reset 2FA, preferably to a hardware key or an authenticator app. Then review your active sessions, API keys and withdrawal addresses, and remove anything you do not recognise. If you shared a recovery phrase, treat that wallet as compromised and move the funds to a new one. Remember that Coinbase support will never ask for passwords, 2FA codes or seed phrases. Defenders should block the domain and look for lookalike domains that combine numbers with brand names in mail and DNS logs.

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.

After a phishing incident
针对受害者的建议与指导
Choose the steps that match what you shared. Keep a copy of this report alongside your own records.
我应该立即采取什么措施？
紧急
Stop using the suspicious site. Open the real service through its official app or an address you already trust.
更改所有密码 — 电子邮件、Exchange 账户，以及任何使用同一密码的账户
启用双因素认证 使用身份验证器应用（而非短信）。禁用基于短信的恢复功能
冻结卡片 如果您在钓鱼网站上输入了银行信息
我应该为报告收集哪些信息？
联邦调查局（FBI）指南
Keep original emails, receipts, messages and screenshots in a secure place. A factual timeline helps the receiving authority understand what happened. IC3 evidence guidance ↗
Payment records — if you paid, save the receipt, amount, date, payment provider and recipient details.
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
当地警方 — 即使无法立即采取行动，也能留下正式记录
A report is not a guarantee of recovery or investigation, but prompt, accurate transaction data can help authorities and service providers trace the incident.
How do phishing scams typically work?
虚假网站 — 与正规网站完全一致的克隆网站，仅域名略有改动
猪的屠宰 — 通过Telegram/WhatsApp/交友软件花数周时间建立信任，随后钱被骗走
退款诈骗 — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
