BRASILIA, July 2 (Reuters) - Brazil's central bank said on Wednesday that technology services provider C&M Software, which serves financial institutions lacking connectivity infrastructure, had reported a cyberattack on its systems.
The bank did not provide further details of the attack, but said in a statement that it ordered C&M to shut down financial institutions' access to the infrastructure it operates.

C&M Software commercial director Kamal Zogheib said the company was a direct victim of the cyberattack, which involved the fraudulent use of client credentials in an attempt to access its systems and services.

C&M said critical systems remain intact and fully operational, adding that all security protocol measures had been implemented. The company is cooperating with the central bank and the Sao Paulo state police in the ongoing investigation, added Zogheib.
Brazilian financial institution BMP told Reuters that it and five other institutions experienced unauthorized access to their reserve accounts during the attack, which took place on Monday.
BMP said the affected accounts are held directly at the central bank and used exclusively for interbank settlement, with no impact on client accounts or internal balances.
