Nubank Sent False Liquidation Alerts After Internal Software Error

Overview

• On Friday, June 12, roughly 20,000 Nubank customers received in‑app notifications, emails and push messages saying the bank was in extrajudicial liquidation and instructing clients to seek compensation from the FGC.
• Cofounder Cristina Junqueira said a submitted pull request activated a preconfigured emergency protocol by mistake and she apologized for the error.
• The Central Bank has denied issuing any liquidation order and Nubank says the mistake was fixed, its licenses and core operations are intact, and normal services continue.
• Some customers reported transferring or withdrawing funds after the alerts, highlighting immediate trust and short‑term liquidity risks for the fintech.
• Internal and external cybersecurity reviews are ongoing to determine whether the cause was an automation or CRM misconfiguration, compromised credentials or internal misuse, and regulators are expected to demand explanations and tighter safeguards for automated crisis communications.
