A major security breach hit Brazil's banking infrastructure, resulting in a loss of $140 million.
The breach occurred through an insider threat where hackers purchased employee log-in credentials for $2,700.
Hackers targeted C&M Software, a key service provider connecting the Central Bank of Brazil to local financial institutions, leading to significant financial losses.
Experts suggest that decentralized blockchain technologies could provide better protection against such breaches as centralized systems become more vulnerable to cyber attacks.
