C&M Software Hacked, $140M Stolen from Six Brazilian Banks
Initial Breach and Funds Stolen
Brazilian service provider C&M Software, a central hub connecting Brazil’s Central Bank to local banks and financial institutions, was compromised in a hack on Wednesday, resulting in the theft of 800 million Brazilian reais ($140 million USD).
The incident unfolded after an alleged C&M employee sold login credentials to a threat actor for approximately $2,700, according to São Paulo newspaper. This allowed the hackers to infiltrate the software system, gaining access to reserve accounts of six central bank-connected institutions to drain funds.
Funds Laundered via Cryptocurrency
Onchain investigator ZachXBT reported that an estimated $30 million to $40 million of the stolen funds were converted into Bitcoin (BTC), Ether (ETH), and USDT (USDt). The threat actor laundered these cryptocurrencies through various Latin American exchanges and over-the-counter (OTC) trading platforms before attempting to integrate them into the broader traditional economy.
Systemic Vulnerability and Expert Analysis
While details surrounding the final disposition of the majority of the stolen Bitcoin and wallets involved remain under investigation, the attack underscores the escalating risks posed to centralized financial technology systems.
According to Chainalysis data cited in the report, attacks on centralized services surged significantly during Q3 and Q4 2024. The current C&M incident exemplifies the vulnerability inherent in centralized systems – single points of failure where compromising one element can lead to catastrophic outcomes for multiple interconnected institutions.

AI Amplifies Centralized System Risks
Experts have highlighted that centralized systems are increasingly attractive targets as artificial intelligence refines hacking capabilities. The pitch for decentralized blockchain solutions grows louder in this context.
Eran Barak, CEO of Shielded Technologies, emphasized that privacy-focused tools are becoming essential against AI-driven threat actors. He noted that central repositories containing vast amounts of sensitive financial data or capital offer massive returns compared to targeting individual components.
Decentralized blockchain technologies like zero-knowledge proofs (ZKPs) make systems less attractive to hackers – the ROI would be significantly lower when only individual wallets are vulnerable rather than entire databases. Cybercriminals are likely to move on.
