In the early hours of this Friday (8), a series of videos from Nubank customers began to circulate on social media, revealing a bug that allowed withdrawals to be made at ATMs on the Banco24Horas network, even without an available balance or limit. Withdrawals, made using the credit function, reached R$1,000 per transaction, according to reports.
The incident quickly went viral, putting the name of the Nubank among the trending topics on X (formerly Twitter). The noise generated by the system failure caused a real rush to ATMs, especially at gas stations. Some videos (below) show queues of customers taking advantage of the gap, while others mention the arrival of military police to contain the situation. There are even reports of the presence of a PM caveirão in Rio de Janeiro, but there is still no official confirmation.
Nubank statement
In response, Nubank confirmed the system failure and informed that the debit withdrawal service was normalized. The institution stated that it is investigating the incident and working to restore the withdrawal via credit card as quickly as possible. The bank also reinforced its commitment to keeping customers updated on any new developments.
This incident raises concerns about the security and reliability of the systems of large financial institutions, highlighting the importance of preventive measures to avoid losses for both customers and the bank itself.

**Interview with Financial Technology Expert Dr. Maria Gomes on the Recent Nubank Withdrawal Bug**
**Editor:** Thank you for joining us today, Dr. Gomes. The recent bug that allowed Nubank customers to withdraw cash without available funds has caught significant media attention. Can you explain how such a bug can occur in a financial app?
**Dr. Gomes:** Thank you for having me. Bugs like the one we saw with Nubank can occur due to multiple factors, including coding errors, system updates, or unexpected interactions between different services. This particular bug involved the credit function of their system, which should validate that a customer has sufficient credit before approving a withdrawal. When this validation fails, it can lead to scenarios like what we witnessed.
**Editor:** The incident reportedly led to long queues at ATMs, with an influx of customers trying to take advantage of the situation. What are the potential legal and ethical implications for customers who withdrew cash under these circumstances?
**Dr. Gomes:** This situation poses complex legal and ethical issues. Legally, customers could be held accountable for withdrawing funds they were not entitled to, as they may be considered unauthorized withdrawals. Ethically, it raises questions about exploiting a system flaw. Most importantly, customers should be cautious about taking advantage of such glitches, as financial institutions have the right to pursue corrective action.
**Editor:** Nubank has stated that they are investigating the issue. What steps should companies take to prevent such incidents in the future?
**Dr. Gomes:** Companies must prioritize robust testing before deploying updates, as well as continuous monitoring of their systems. They should also have emergency protocols in place for quick responses when such bugs are identified, including communicating with customers promptly. Additionally, implementing stronger validation checks for transactions could help prevent unauthorized withdrawals.
**Editor:** what should consumers do in situations like this when they notice a technical glitch in their banking applications?
**Dr. Gomes:** Consumers should report the glitch to the bank immediately and avoid using it to make unauthorized transactions. Transparency is key in these scenarios. Continuing to use a known loophole can lead to penalties or being blacklisted by the bank. It’s crucial for consumers to be responsible and ethical in their banking practices.
**Editor:** Thank you, Dr. Gomes, for your insights on this significant issue. We’ll be following the developments closely as Nubank continues their investigation.
**Dr. Gomes:** Thank you for having me. It’s essential to keep the conversation going around security and responsibility in financial technology.
