Brazil's financial system has been hit by a cyber attack, and the central bank has urgently intervened in the investigation

On July 2 local time, at least six Financial Institution Groups in Brazil suffered cyber attacks. Hackers took advantage of system vulnerabilities of third-party payment service providers to initiate large-scale illegal transfers. At present, the Central Bank of Brazil has not released the specific amount involved and the list of affected Financial Institution Groups. According to an investigation by the Central Bank of Brazil, the entrance of this attack is not the bank's own system, but its authorized payment service provider C & M Software. At present, the Brazilian Federal Police and the Sao Paulo State Police have been involved in the investigation. The Central Bank of Brazil has urgently interrupted the system interface of the service provider and asked relevant institutions to suspend the transfer operations initiated by the service provider. At the same time, the Financial Institution Group was ordered to comprehensively check the qualifications of the third-party service provider.
