Finance messaging giant SWIFT plans new measures to help banks combat fraud, after a gang broke into Bangladesh’s central bank in February and stole £57 million pounds—and were only caught because one of them made a typo in a £15 million transfer.

The banking communications network, which allows financial institutions across the world to send each other secure messages about their transactions, is introducing “Daily Validation Reports,” which it bills as a mechanism to help customers detect unusual patterns in their message flows, and give them more of a chance “to identify possible fraud attempts and improving the likelihood they can cancel any fraudulent transfers.”
