Banco BCR Credit Card Leaks by Maze Ransomware Operators – Part 2

As expected by Cyble’s researchers, the Maze ransomware operators released the second part of credit card leaks of Banco De Costa, which is one of the strongest state-owned commercial banks that operate in Costa Rica. 

The Banco de Costa Rica was being established on 20 April 1877. Banco de Costa Rica (BCR) is a state-owned commercial bank that operates in Costa Rica. With equity of $806,606,710 and assets of $7,607,483,881, the bank has established itself as one of the strongest banking companies in both Costa Rica and Central America. The bank began primarily as a private commercial bank until it was designated a currency issuer and exclusive manager of public revenues in the last decade of the 19th century. After the bank nationalization decree of 1948, Banco de Costa Rica became a financial entity with a major role in the development of the country. 

Just like previously, the Cyble Research Team has identified and verified this data leak, which consists of a CSV file of around 2GB containing details of various Mastercard and Visa credit cards. This data leak includes confidential details of around 5.8 million credit cards. It seems that the Maze ransomware operators have made this data leak due to the Banco de Costa not taking the previous data leak seriously. Along with that, if the scenario remains the same then the Maze ransomware operators would be publishing this type of leak every week. Here are some snapshots of the data leak from the large CSV file-:
