Good news, you’ve not been hacked.
It appears that the folks at ModeRoom.com provide plugins for wordpress that allow users to show Daily Quotes on their sites. The feed for these quotes comes directly from the moderoom.com domain.
The moderoom.com domain has expired and is now a parked page. It’s very typical of a parked page not to allow itself to be framed in another window so when your page attempts to load the moderoom.com quote plugin, the parked page coded busts the frame and redirects to their page.
To fix this issue, simply login to your wordpress site, deactivate or uninstall the plugin and all is back to normal.
