Digital security is a growing concern in an increasingly connected world, and recently a new incident has drawn attention. In the context of an era in which financial transactions are predominantly conducted online, such as PIX, data leaks can generate significant apprehension, both for institutions and their customers.
The recent case involving Banco BTG Pactual highlights how technical failures can compromise the privacy of information. Even if these failures do not involve sensitive data.
Data Leak Details
On August 15, the Central Bank (BC) announced an incident that affected the security of data linked to 8,032 Pix keys. At the time, they belonged to Banco BTG Pactual customers. The information was exposed due to specific failures in the institution's systems between July 23 and August 5 of this year. Despite the seriousness of the situation, the BC assured that sensitive data, such as passwords, information on financial transactions and balances, were not compromised. The leaked information was of a registration nature, with usernames, masked CPF, financial institution, branch, account number and type.
The measure adopted by the Central Bank to notify affected customers was specific. People whose data was exposed will be informed exclusively through the institution's app or internet banking. The BC chose not to use other communication channels, such as messaging apps, phone calls, SMS or email. All this to ensure the privacy and security of notifications.

Bank Measures and Response
BTG Pactual responded to the incident and stated that the leak was the result of specific queries made with CPFs that were obtained outside the banking system. According to the bank's official statement, these queries allowed viewing only data related to the branch and the checking account associated with these CPFs. The bank assured that it immediately restricted access to this information and reinforced that there was no hacking of the institution's internal systems. The statement also highlighted that sensitive data, such as password information and confidential financial data, were not exposed.
BTG Pactual emphasized that information security is a priority for the institution and assured that it is available to answer any questions from customers through its service channels. The note also reiterated that the entity has taken the necessary measures to investigate the incident in detail and that it will apply current regulations as necessary.
Security and Impact Overview
This incident is part of a growing pattern of data breaches in the financial sector, with eight similar incidents recorded this year alone. The Central Bank maintains a dedicated page to record and track these incidents, highlighting the importance of monitoring and mitigating security risks. Although the breach in this particular case did not involve critical data, it serves as a reminder of the continued need for vigilance and improved cybersecurity measures.
Transparency by financial institutions in reporting and responding to these incidents is crucial to maintaining customer trust and ensuring the integrity of banking systems. The BTG Pactual situation highlights the importance of robust systems and effective security practices to protect sensitive data and prevent future incidents. With the increasing digitalization of finance, information security will continue to be a central issue in risk management and the protection of customer data.
