Swift, the interbank messaging system embroiled in a global bank-hacking controversy, said it will start sending daily reports to clients that will allow them to verify payment instructions and quickly identify anomalies.

The new reports, which will be introduced in December, are aimed at one of the prongs of an attack by hackers used when they stole $81 million from the Bangladesh central bank in February. In that case, the hackers disabled the printing of message confirmations, delaying discovery of the theft.

The new reports will be sent through a separate channel to banks' payments and compliance staff in order to ensure clients get the information, Swift said in an emailed statement.
