Recent attempt by a third party to obtain customer information via our New Payments Platform (NPP) PayID service.

Westpac recently detected the misuse of our PayID functionality, which triggered preventative action.


As a customer registering to use the PayID service, you consent to your PayID name and phone number being visible to other users when they make payments to your PayID. It is also helpful to prevent any payments going to the wrong recipient.


We were recently targeted by a third party using an automated program to search random mobile phone numbers in the NPP database of PayIDs to identify customer names that correspond with those mobile numbers. The third party only accessed the information displayed on the NPP Register, being the PayID name and mobile number.


Westpac takes the protection of customer data and customer privacy extremely seriously and we have taken actions to help prevent the PayID service from being misused in this way through Online Banking.


Since we implemented preventative action, there has been no further inappropriate activity of this nature detected. As an additional precaution, we have also put in place enhanced monitoring across our New Payments Platform PayID service.


For those individuals who have had their mobile phone numbers matched with their PayID names, we wish to assure you that no financial information was accessed.


Any Westpac PayID registered customer who has been impacted by this incident has been contacted.
