On the other hand the ridiculous response is moronic. Someone needs to loose their job over that. Repeating a canned answer that fails to answer the question is the height of arrogance and adds nothing to the conversation.
If they don't know then they need to say that it is being dealt with by another team and the information will be available at a (defined) later date. In the mean time people can rest assured that their money is secure and CBA will guarantee it against these and other threats.
What a way to turn a great feature (their security guarantee) into a negative by treating people as mushrooms.
Changed my password anyway, like I did with every other service I use.
