    Hi. I´m not sure if got it it right.

    This will happen only when I´m printing the boleto from a web page or also when I´m typing in the Bank´s payment page ?

    • Changing of data as it is submitted is an older type of fraud. The news we reported in this article was about changing the information as it was being printed on screen. Both types exist.

      Please notice that both frauds are technically different. When the trojan modifies a boleto number typed during payment, the confirmation page should change this number back to the original one for the fraud to remain undetected. When the boleto itself was changed, this is not required as the user never had access to it in the first place.
