trezor.ustdguide.com is a phishing page posing as Trezor, the hardware wallet maker. It targets people who keep crypto on a Trezor device. The brand name sits in the subdomain so the address looks official at a glance, but the site is hosted on an unrelated domain. PhishDestroy first saw it on 2026-10-13. The site went offline on 2026-10-14, and its DNS was still inactive when we last checked on 2026-10-19.
How the scam works
Fake Trezor pages usually copy the look of the official setup or support flow. They then tell the visitor to "verify," "restore," or "update" the wallet by typing in the 12- or 24-word recovery phrase. Anyone who holds that phrase controls the wallet, so the operator can rebuild it on their own device and empty it. The hardware device never has to be touched. The page displayed only its own hostname as a title, which fits a short-lived throwaway page more than a polished clone.
Evidence
urlscan.io rated the page malicious and detected Trezor branding on it. Spamhaus lists the domain in its DBL as a phishing domain. VirusTotal coverage was thin when checked on 2026-10-13: only CRDF and DNS8 flagged it, out of 92 engines. That low count reflects how new the page was, not that it was safe. PhishDestroy has it on its blocklist.
Infrastructure
The domain was registered on 2026-10-06 through Cloud Yuqu LLC, one week before we detected it. It stopped resolving a day after detection. That pattern of registering, using the domain briefly, and abandoning it is typical of phishing runs that rotate through disposable domains. The site was hosted at 23.148.180.108 on NetLab Global in the US. It used a free Let's Encrypt certificate, so the browser padlock said nothing about whether the site was legitimate.
What to do
If you typed your recovery phrase into this site, treat the wallet as compromised. Set up your Trezor as a new wallet with a freshly generated phrase, then move any remaining funds there immediately. Never re-enter the old phrase anywhere, and if you used a passphrase, assume it is exposed too. Trezor never asks for your recovery phrase on a website, so any page that does is a scam. Defenders should block trezor.ustdguide.com and its parent domain, and watch for new subdomains on it that carry wallet brand names.

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
