Maze ransomware operators claim to have breached Banco de Costa Rica and hold over 11 million credit card records (about 4 million unique, including ~140k US cards). Cyble verified the press release and posted evidence that the actors published encrypted/hidden samples; the group says this is the second breach of the bank in eight months and is pressuring the institution to improve security.
