ZachXBT: Brazil's Central Bank service provider C&M Software was attacked, resulting in a loss of 140 million USD.

ChainCatcher news, encryption detective ZachXBT shared in his personal channel that "one of the most outrageous cases that happened in 2025 is undoubtedly the recent cyber attack on Brazil's Central Bank service provider C&M Software, with losses amounting to approximately $140 million (800 million reais). 6 financial institutions were unauthorizedly accessed on June 30, 2025, with attackers breaching their reserve accounts at the Central Bank. The hackers then converted fiat currency into BTC, ETH, and USDT through over-the-counter (OTC) traders and cryptocurrency exchanges in the Latin American region. It is estimated that at least 30 to 40 million dollars were converted into encryption. According to subsequent reports from Brazilian law enforcement agencies, the hacker paid only about $2,760 (15,000 reais) to buy the company login account and password from an employee of C&M Software. I have been assisting in tracking the funds, freezing accounts, and identifying unmarked over-the-counter traders. When it can be made public, I will disclose the addresses related to this theft. Currently, this incident has received almost no attention in the media outside of Brazil.
