History

Historical Context

In February 2016, hackers using the North-Korean Lazarus Group sent 35 fraudulent SWIFT messages from Bangladesh Bank’s New York Federal Reserve account, stealing $101 million—$81 million to the Philippines and $20 million to Sri Lanka—while the Fed blocked $850 million after a misspelled instruction. Earlier 2013-15 SWIFT breaches of Sonali Bank and a Vietnamese bank prompted SWIFT to impose mandatory security controls worldwide.
