SWIFT on Monday rejected allegations by officials in Bangladesh that technicians with the global messaging system made the nation's central bank more vulnerable to hacking before an $81 million cyber heist in February.

The comments were in response to a Reuters story that cited Bangladeshi police and a central bank official as saying that SWIFT technicians introduced security holes into the bank's network while connecting SWIFT to Bangladesh's first real-time gross settlement (RTGS) system.

"SWIFT was not responsible for any of the issues cited by the officials, or party to the related decisions," the Brussels-based bank-owned cooperative said in a statement posted on its website.

"As a SWIFT user like any other, Bangladesh Bank is responsible for the security of its own systems interfacing with the SWIFT network and their related environment – starting with basic password protection practices – in much the same way as they are responsible for their other internal security considerations," the statement said.

Reuters has not been able to independently verify the allegations by Bangladeshi officials about the SWIFT technicians.
