Which version of Wordpress and modules you were using? Do you have logs of the incident? I am including RBC to this 
email as they probably are interested of the details. There might be other similar phishing pages active.

www1.royalbank.com has address 142.245.40.233
www.royalbank.com has address 142.245.34.203
royalbank.com has address 142.245.1.203
www.rbcroyalbank.com has address 142.245.1.15
rbcroyalbank.com has address 142.245.1.15

Reading this bug-raport http://core.trac.wordpress.org/ticket/17969 says to me that there is still possibility of 
vulnerability. I'll bet it is in one of the modules as well.
