The Bangladesh Bank BangSwift heist used authenticated SWIFT messages and custom malware tailored to SWIFT Alliance Access and an Oracle database environment to hide or manipulate transaction records, with reporting describing attempted transfers of roughly $951 million and about $101 million stolen. BAE Systems, Symantec, and Anomali connected the SWIFT malware to a wider bank-targeting toolset through shared wiping routines, Trojan.Banswift, Backdoor.Contopee, and Lazarus-associated Operation Blockbuster code overlaps, supporting the existing Bluenoroff attribution for a financially motivated DPRK-linked banking operation.
