In December, hackers tried to steal 55 million roubles from Russian state bank Globex using the SWIFT system, and digital thieves made off with $81 million from Bangladesh Bank in February 2016.

 

Unknown hackers stole 339.5 million roubles ($6 million) in an attack on the SWIFT international payments messaging system in Russia last year, the Russian central bank said on Friday. The disclosure, buried at the bottom of a central bank report on digital thefts at Russian banks, is the latest in a string of attempted and successful cyber heists using fraudulent wire-transfer requests.

The central bank said it had been sent information about “one successful attack on the workplace of a SWIFT system operator. “The volume of unsanctioned operations as a result of this attack amounted to 339.5 million roubles,” the bank said.

The central bank declined to provide further details. A spokeswoman for SWIFT, whose messaging system is used to transfer trillions of dollars each day, said the company does not comment on specific entities.

“When a case of potential fraud is reported to us, we offer our assistance to the affected user to help secure its environment,” said the spokeswoman, Natasha de Teran.
