I downloaded the latest version of cmsmadesimple-1.9.4.2-full and am confused why plugins/function.embed.php it includes an iframe that points to http://www2.romanianoffice.ro/forum/index.php. Does anyone know what the deal is? Here is the full code of the file:

Code: Select all

Thanks for the fast response. I guess I'm still wondering what it's doing there?

All of my CMS MS sites have recently been repeatedly hit with a Mass Meshing Injection and I'm just making sure I cover all my bases trying to protect against future attack.
