BusinessDay understands the matter is under police investigation, with CommBank issuing replacement cards from yesterday afternoon to about 8000 customers who might have been affected.

ABC News also reports on the breach:
All major banks have blocked, restricted or cancelled what totals thousands of credit cards in response to a potential security breach.
All four major banks and St George have confirmed to the ABC that some customers’ cards have been cancelled, blocked or restricted due to fears they had been compromised and would be open to fraud.

CBA says a merchant EFTPOS terminal used by some of its customers was not secure, and there is a possibility customer information was ‘skimmed’.
