There was a security flaw in v.4.7 and v.4.7.1 that allowed hackers to deface over 40,000 sites. They're not moving on to using those sites for more nefarious purposes.
The fix? Upgrade to 4.7.2, immediately.
Note that some hosts upgraded sites automatically once 4.7.2 was released. If you're not sure if you need to upgrade, look at the top of any tool page in the back end. A link will say that 4.7.2 is available.
Once you've upgraded, check your site's pages and posts to see if there was any damage done to it. Fix anything you find.
