This was a sophisticated attack and it is likely the "phishing emails" that will be delivered to inboxes will also be very sophisticated and will look authentic.  Don't click on any email that requests that you verify your account, asks you to sign-in, re-register, approve your new password or any link that comes in an email.  As information become available this post will be updated.
