Nubank Sent False Liquidation Notices After Developer Triggered Emergency Flow

Overview

• Nubank customers received official-looking push notifications and emails on Friday, June 12 that incorrectly said the bank had been placed in extrajudicial liquidation and directed users to seek compensation from the Fundo Garantidor de Créditos.
• The Banco Central publicly denied any liquidation and Nubank says the messages were caused by a developer who accidentally activated an emergency communication flow during a code change; the company says the issue was fixed and the affected group was roughly 20,000 users.
• Some customers reported transferring or withdrawing money after seeing the false alerts, and company chat responses reportedly gave mixed information to users before the bank corrected the messages.
• Cybersecurity experts are examining whether the root cause was an automation or CRM failure, a misused message template, or credential misuse, and Nubank says it has opened an internal investigation and is implementing safeguards to prevent a repeat.
• Officials and reporters note that only the Banco Central can order a bank liquidation and customers are advised to ignore unsolicited links or payment requests, verify information through official Nubank channels, and watch for fraud attempts that could exploit the episode.
