Bradesco announces 53,000 customer data leaks

A new data leak may expose data from around 53,000 Brazilians. Banco Bradesco reports that its subsidiary Bradesco Financiamentos has detected an incident that may have allowed unauthorized access to client contract data.

The bank said in a statement to Reuters that “all necessary measures have been taken to resolve the incident, as well as communication with customers and the competent authorities.”

The bank also reported that the potential leak did not jeopardize the integrity of access to customer transaction systems.

It should be noted that last month, Banco Pan reported that it had recently discovered a “vulnerability” in the technology provider’s platform, which is used in the card chip customer service center, which allowed customer information to be leaked.

This allowed, according to the financial institution, the unauthorized copying of registration data, available limit and debt balance “without disclosing full card data, passwords or any data with direct financial risks to the customer and the bank.”

So far the number of clients that have been revealed has not been reported. The financial institution, according to its press office, has about 17 million active customers.

In February of this year, the Central Bank reported a leak of data of a “registration nature” relating to PIX to clients of the financial institution Logbank Soluções em Pagamentos S/A.

According to BC, the registration data associated with 2,112 PIX keys, which contains the username, CPF, relationship institution and account number, has been leaked.
