Banco de Costa Rica

Hackers gained access to the network of Banco BCR, the state-owned Bank of Costa Rica, and stole 11 million credit card credentials along with other data.

This attack was conducted by the operators of the Maze Ransomware.

Of these credit cards, 4 million are stated to be unique and 140,000 allegedly belong to people from the USA.

As proof of this theft, Maze posted what they say are 240 credit card numbers, with the last four digits removed, along with expiration dates and credit card verification codes (CVC).
