SWIFT warns of new successful cyber thefts against banks

Cyber attacks targeting banks using the global transfer service SWIFT have successfully stolen funds in the months following February’s Bangladesh central bank heist, according to a recently discovered letter sent to banks in November.

In the letter, sent on the 2 November to banks worldwide and uncovered today by Reuters, SWIFT warned that due to increasingly sophisticated attacks, there was an escalating threat against banks’ systems. It read: “The threat is very persistent, adaptive and sophisticated – and it is here to stay.”
