Brazil's investment bank BTG Pactual announced on March 23 that it has started gradually restoring payment operations conducted through the Pix instant transfer system after proactively suspending the service following a hack attack. Approximately 100 million reais were transferred by hackers after the network attack on March 22, with over half of the transferred funds already recovered.

While the bank did not disclose the specific percentage of funds recovered, it mentioned that efforts are ongoing to recover the remaining amount transferred by hackers (estimated to be between 20 million and 40 million reais). The interruption of the Pix instant transfer service occurred after abnormal activity was detected by the system, triggering the institution's security mechanisms. The immediate suspension of the Pix service was a preventative measure taken in response. The bank stated that the issue stemmed from internal processes and did not impact the overall structure of the payment system.

The Central Bank of Brazil confirmed the anomaly and clarified that the Pix system itself and the central bank's instant payment infrastructure were not compromised. The incident was identified as an internal issue confined to the systems of BTG Pactual bank. BTG bank emphasized in its statement that customer accounts were not breached in this incident, and there was no leakage of personal banking data. The bank stated that information security remains a top priority and will continue to provide support and explanations to customers through various service channels.
