The Central Bank of Brazil has acknowledged the exposure of data belonging to approximately 150 PIX keys, a popular instant payment system in the country. The bank has emphasized that the breach did not involve financial transactions or personal information, but rather the exposure of technical data related to the keys.

The bank has initiated an investigation into the incident and is working to mitigate any potential risks. Users are advised to remain vigilant and monitor their accounts for any unauthorized activity. The bank has also recommended that users change their PIX keys as a precautionary measure.

The PIX payment system has gained widespread adoption in Brazil, with over 130 million users. The system allows users to make instant payments using their mobile phones, without the need for bank account numbers or other sensitive information. The exposure of PIX keys could potentially compromise user accounts and facilitate unauthorized transactions.
