Bangladesh Central Bank heist probe info to be held to avoid tipping off 'foreign perpetrators': Report
Bangladesh's central bank has said it is withholding findings of investigations into the cyber theft of $81 million from its account at the Federal Reserve Bank of New York to avoid tipping off the "foreign perpetrators" of the hack.
Bangladesh authorities had said earlier they were considering suing the Reserve Bank over the loss of the funds.
Investigators probing the cyber heist of $81 million from the Bangladesh central bank connected it on Friday to the hack at Sony Corp's film studio in 2014, while global financial network SWIFT disclosed a previously unreported attack on a commercial bank.
