A hacker acquired $140 million from Brazilian banks by spending only $2,760 to bribe an employee of C&M Software, a company facilitating connections to Brazil's central banking infrastructure. The breach allowed unauthorized access to the reserve accounts of multiple financial institutions on June 30, draining funds within hours. The compromised employee, João Nazareno Roque, sold his credentials and aided in creating software to facilitate the heist. Following the theft, criminals converted $30-40 million into cryptocurrencies like Bitcoin, Ethereum, and Tether. Law enforcement is investigating this incident as the largest digital heist in Brazilian history, highlighting vulnerabilities in the banking system despite previous cybersecurity investments. The attack exploited legitimate credentials, and authorities are working to trace cryptocurrency transactions linked to the crime while ensuring preventive measures against future breaches. The incident resulted in prompt actions from Brazil's central bank to mitigate damages and investigate further.
