oberkonto-tan.com is an impersonation phishing site that presents itself as a Cloudflare page. Its name pairs "Oberkonto" with "TAN", wording that evokes German online banking and transaction codes, which suggests it is aimed at bank customers. PhishDestroy first flagged it on 2026-08-26. As of 2026-10-19 the site was still online and its content sat behind a protective challenge.
How the scam works
The page carries the title "Attention Required! | Cloudflare", copying the browser-check screen that millions of people click through every day without a second thought. Schemes like this use that familiar step to lower suspicion, then steer the visitor toward a form that asks for account logins, personal details or one-time codes. Anything typed there goes straight to the operators, who can then sign in or authorise transactions in the victim's name. The title matches Cloudflare's standard interstitial, and we classify the site as impersonation phishing.
Evidence
On 2026-10-07, five of 92 VirusTotal engines flagged the domain: alphaMountain.ai, CRDF, Forcepoint ThreatSeeker, Gridinsoft and SOCRadar. That is a low hit rate, typical for a phishing domain that only shows its real content behind a challenge, so most scanners never reach the lure. The domain also appears in four AlienVault OTX threat pulses, which means other researchers have tied it to malicious activity. PhishDestroy lists it on its blocklist.
Infrastructure
The domain was registered through Tucows Domains Inc. on 2026-08-25, just one day before we detected it. Domains put to work that quickly are a hallmark of throwaway phishing campaigns. The site resolves through Cloudflare, Inc.'s network, with the address geolocated to Canada. Because the operators sit behind Cloudflare's own proxy, a page wearing Cloudflare branding looks unusually convincing.
What to do
If you reached this site and typed in a username, password or banking details, change those passwords at once from the real service and turn on two-factor authentication. If you entered an online-banking login or a TAN code, call your bank immediately, ask it to block pending transfers, and check recent account activity. Watch for follow-up emails or calls that cite the details you entered. Defenders should block the domain at DNS and web proxies and search logs for users who visited it after 2026-08-25. They should also remind staff that a real Cloudflare check never asks for credentials or bank codes.

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 oberkonto-tan.com)
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
