The Polish DPA has fined mBank EUR 940,000. The bank had suffered a data breach in which an employee of the controller sent documents containing customer data to the wrong recipient. The documents contained information such as names, account numbers, dates of birth and ID card numbers. Although the documents were returned to mBank, the envelope had been opened , meaning that third parties may have had access to the documents. During its investigation, the DPA found that, although the controller informed the DPA of the incident, it failed to notify the data subjects in a timely manner.
