Brazilian banking giant’s app bares customer data

Accidentally leaked credentials

On Dec. 9, Banco do Brasil clients who conducted mobile banking through iOS and Android apps could see information such as balance and statements from other, random account holders. The damage would have been greater, had not transfers and payments been password protected.

The bank is Brazil’s largest. The issue lasted for about an hour. Company officials took the mobile service offline “after the bank started to receive a barrage of complaints from hundreds of customers on Twitter,” ZDnet reports.

Bank officials told the publication there has been some "inconsistency and intermittence" of customer information during the updating process of the apps, but the bank said its security systems "remained active" and "no data has been at risk in the event of financial transactions."

The app page on Google Play indicates that between one and five million users have downloaded the Android app.
