Reports of additional attacks against banks that use SWIFT, the global financial transaction messaging network, came to light Wednesday. The attacks were reportedly persistent, sophisticated and in some cases successful, impacting an undisclosed number of financial institutions.
It’s the latest development since February when cybercriminals used SWIFT to steal $81 million in a Bangladesh Bank heist. Reports of the latest bank attacks come from a private letter obtained by the Reuters news agency sent by SWIFT to its clients informing them of the attacks and urging them to shore-up their cyber defenses.
The letter told clients that SWIFT customer “environments” have been compromised and that the possibility of a “threat is persistent, adaptive and sophisticated – and it is here to stay,” according to the Reuters.
