tzr-ncud7.sia04.workers.dev is an impersonation phishing page hosted on a Cloudflare Workers subdomain. PhishDestroy classifies it as impersonating Cloudflare, while urlscan.io detected Trezor branding on the site. The "tzr" prefix in the hostname also echoes Trezor, so the likely targets are hardware-wallet owners. We first saw it on 2026-09-10. It went offline on 2026-09-11 and was still dead when last checked on 2026-10-19.
How the scam works
Pages like this copy a trusted brand's look so that visitors treat a free throwaway subdomain as an official service. When the theme is Trezor, the usual goal is to get the victim to type their recovery seed phrase into a fake update, verification or recovery form. Anyone holding that phrase can empty the wallet. The page title now reads "Suspected Phishing | Cloudflare", which is Cloudflare's own warning page rather than the original lure, while our classification is Cloudflare impersonation.
Evidence
urlscan.io returned a malicious verdict and identified Trezor as the brand on the page. VirusTotal showed 0 detections out of 89 engines on 2026-09-10, the day we found it. A clean VirusTotal result that early should not reassure anyone, because short-lived phishing pages often go down before antivirus vendors catch up. PhishDestroy is currently the only blocklist listing the domain.
Infrastructure
The site ran on Cloudflare's Workers platform, with Cloudflare, Inc. as registrar and hosting on CLOUDFLARENET at 188.114.96.3 in the US. Free workers.dev subdomains cost nothing and can be created in seconds, which suits a site built to last only a short time. The content is now marked as blocked by the provider, which matches the warning title. The site lived for about a day between our first sighting and the takedown.
What to do
If you typed a Trezor recovery seed into this site, treat the wallet as compromised. Set up a new wallet on your device with a fresh seed and move any remaining funds there right away. Never enter a seed phrase on a website, because the real Trezor never asks for it online. Defenders should block this hostname and watch other workers.dev subdomains for wallet-brand keywords like "tzr", since a takedown on one subdomain does not stop the operator from opening another.

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
Rekomendasi & Saran bagi Para Korban
Choose the steps that match what you shared. Keep a copy of this report alongside your own records.
Apa yang harus saya lakukan segera?
Mendesak
Stop using the suspicious site. Open the real service through its official app or an address you already trust.
Ubah semua kata sandi — email, akun Exchange, apa pun yang menggunakan kata sandi yang sama
Aktifkan 2FA menggunakan aplikasi otentikator (bukan SMS). Nonaktifkan pemulihan berbasis SMS
Kartu pembeku jika Anda telah memasukkan detail perbankan di situs phishing tersebut
Informasi apa saja yang sebaiknya saya kumpulkan untuk laporan saya?
Pedoman FBI
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.
Tanggal dan waktu yang tepat — dari setiap transaksi dan kontak pertama dengan penipu
Tangkapan layar — situs web penipuan, pesan obrolan, email, transaksi dompet digital, media sosial
Semua URL & domain digunakan oleh penipu (termasuk tzr-ncud7.sia04.workers.dev)
Komunikasi — email, pesan teks, nomor telepon, dan nama pengguna yang digunakan oleh penipu tersebut
Meskipun kamu belum mengetahui semua detailnya — tetap saja ajukan laporan. Informasi yang tidak lengkap tetap dapat membantu penyelidikan.
Ke mana saya harus melaporkan penipuan ini?
FBI IC3 — Pusat Pengaduan Kejahatan Internet (Laporan tingkat federal AS)
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
Polisi setempat — membuat catatan resmi, meskipun mereka tidak dapat bertindak segera
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?
Situs web palsu — salinan yang persis sama dengan situs asli, dengan domain yang sedikit diubah
Pemotongan babi — kepercayaan yang dibangun selama beberapa minggu melalui Telegram/WhatsApp/aplikasi kencan, lalu uangnya dicuri
Penipuan pemulihan — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
Penipuan yang didukung oleh kecerdasan buatan — deepfakes, serangan phishing otomatis, dan situs yang dihasilkan oleh kecerdasan buatan (AI) yang membuat penipuan semakin sulit dideteksi
Bagaimana cara saya melindungi diri di masa depan?
Tandai situs resmi — jangan pernah mengklik tautan dari email, pesan langsung (DM), atau iklan
Memverifikasi domain — periksa PhishDestroy Sebelum berinteraksi. Periksa HTTPS, ejaan, dan usia domain
"Terlalu bagus untuk jadi kenyataan" = penipuan — imbal hasil yang dijamin, dukungan dari selebriti, tenggat waktu yang mendesak
