Earlier this month, hackers using credentials purchased from a C&M employee were able to generate unauthorised PIX transactions on client banks and steal at least BRL$ 500 MM, and maybe as much as BRL $ 5 BN, so it's definitely not fool proof.

    That's an interesting claim - how do you know my values and concerns?
