The Banco Central do Brasil has reported a data breach affecting 1,500 individuals who participated in a survey about the Pix payment system. The breach was confirmed on December 5, 2024, and has raised concerns regarding the security of personal information collected by the institution. In a related issue, over 2,000 companies in São Paulo have had their state registrations suspended due to suspected fraud involving the Pix system. These companies reportedly used names similar to public agencies and retail networks, with only one company requesting reinstatement of its registration. The situation highlights ongoing challenges related to the security and integrity of digital payment systems in Brazil.
