I'm running the latest version of WordPress and am using 1and1 as my Web Hosting Company. Recently I've had problems where my index.php and several other files get hacked...
The hack basically injects a very long string that looks like code, but I haven't the slightest clue as to how to decode this string or what it's doing.
I did some research online and it sort of looks like a base64 attack, however, the part of code that appears to distinguish itself as this specific attack "<?php eval(base64_decode('" is not present.
Thanks in Advance!!
Here is a copy of my index.php file:
