MT Intelligence
Nubank is a well-established, publicly traded financial institution (NYSE: NU) headquartered in São Paulo and regulated by Banco Central do Brasil. The domain has been registered for over 12 years, carries valid SSL from Amazon, and shows zero malware detections across our antivirus network and browser blocklists. The site holds RA1000 maximum reputation on Reclame Aqui with an 8.7/10 score, responding to 99.5% of complaints and resolving 92.3% — a strong indicator of legitimate business operations despite the high absolute complaint count (57,544), which is typical for a financial institution serving 135+ million customers. The evidence package shows Nubank actively publishes anti-scam resources and received an official Fraud Prevention Seal from Brazil's National Confederation of Financial Institutions in 2025. The complaints documented in the evidence relate to third-party scams impersonating Nubank (fake SMS alerts, fraudulent call centers), not the official domain itself.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on nubank.com.br and not a lookalike like n-ubank.com.br.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
