But if you use the same login info for multiple sites including a financial site, other non-financial sites may have been affected. And it is a long list of sites that were vulnerable including popular social media sites: Facebook, Instagram, Pinterest, Tumblr, Twitter, Google, Yahoo, Gmail, Yahoo Mail, GoDaddy, Dropbox, Minecraft (I told my kids this last one was evil!).
So to protect sensitive financial information you should consider changing your financial institution login information. If another non-financial external site has been affected, this will ensure your financial website information and services cannot be compromised.
