$140M Crypto Laundering: Brazil’s Central Bank Uncovers Massive Cyber Heist
On June 30, a cyber theft occurred, with hackers making off with an estimated $140 million (R$800 million) by exploiting the reserve accounts of six Brazilian financial institutions using software infrastructure provided by C&M. Now, the Central Bank of Brazil is taking proactive steps to retrieve the stolen funds following their discovery of the culprit.
Central Bank’s Immediate Action Against the Crime
Following the uncovering of the robbery and the perpetrator, the central bank promptly announced a short-term halt in operations for C&M Software. By midweek, the company was back in operation on a limited scale, under close watch.
The Federal authorities have initiated an investigation at the Cybercrime Unit in Brasilia, focusing on the recovery of stolen funds and halting any further money laundering. At present, they are examining a number of queries regarding the individuals behind the hacking incident, as well as other parties who might have benefited from the fraudulent scheme.
Discovery of Brazil’s Cyber Theft of $140 Million
Around 140 million dollars were illegally obtained through hacking C&M software, a service linking Brazil’s central bank with local banks and financial institutions. It is known that at least 30 to 40 million of these stolen funds were transformed into cryptocurrencies like Bitcoin, Ethereum, and Tether.
In this scenario, the conversion from traditional fiat currency to cryptocurrency was facilitated through over-the-counter brokers and digital exchanges in Latin America. Brazilian authorities are investigating whether this process may be linked to a money laundering scheme connected to Brazil’s PIX payment system, a central bank initiative for instant transactions.

The Grand Theft Stemming from Internal Compromise
According to Brazilian authorities, the security breach originated within the company C&M, where an insider, named João Nazareno Roque, confessed to illegally selling internal access credentials to a hacker for approximately 5,000 Brazilian Real (R$).
As a researcher delving into this case, I discovered that my first interaction with the perpetrator, in question, took place in March. At this time, it was alarming to note that the suspect possessed intricate details about my professional role. Subsequently, an unusual transaction transpired where I was covertly remunerated R$10,000 to carry out a series of sophisticated commands within our system, which ultimately resulted in a grand theft.
Final Thought
The large-scale cyber theft of $140 million has sparked a wide range of conversations about fintech security, potential risks from third-party providers, and regulatory supervision. As the investigation continues, Brazilian authorities aim to eradicate such cybercrimes entirely.
