Comments made by a senior American intelligence official on Tuesday appeared to suggest that the North Korean government was behind an attempt to steal nearly $1 billion from a Bangladeshi bank last year. The heist took place in February of 2016, when a computer malware was used to issue several requests to transfer funds from Bangladesh Bank —the state-owned central bank of Bangladesh— using the SWIFT network. The hackers were able to transfer five separate sums of $101 million each to a linked Bangladesh Bank account at New York’s Federal Reserve Bank. However, when further requests were issued, Federal Reserve Bank employees contacted Bangladesh Bank and blocked further transactions. Eventually, most of the transferred funds, which neared $1 billion, were recovered; but the hackers managed to get away with approximately $81 million worth of funds.
Forensic investigators described the heist as technically advanced. The antivirus company Symantec said it identified a piece of code in the malware that is known to have been used by North Korean government hackers in the past. Not everyone agreed with the claim that Pyongyang was behind the bank heist. But those who did, said that it was unprecedented in scope and aggressiveness. Some even said that the heist showed that North Korea’s cyber capabilities were among the most sophisticated and powerful in the world.
Meanwhile the United States government did not comment on the matter. However, this past Tuesday the deputy director of the National Security Agency appeared to confirm reports that North Korea was behind the Bangladesh Bank heist. Rick Ledgett, a 30-year veteran of the NSA, who is due to retire in 2018, was speaking at a public event hosted by the Aspen Institute in Washington, DC. He reminded the audience that private researchers had connected the malware code used in the Bangladesh Bank heist with that used in previous hacking attempts launched by North Korea. “If that linkage […] is accurate”, said Ledgett, it “means that a nation state is robbing banks”. When asked by the moderator whether he believes that to be the case, Ledgett responded…
