My site was just hacked by Amin Safi

Hey,

I just found one of my sites hacked and defaced by this Amin Safi guy.

I then noticed all the other directories on my domain had this OwNeD.php in them which is what he used to deface my other site, although he hadn’t redirected any other sites to it, just put it in each directory within my public_html folder. – he did over the test domains too.

I have since deleted any copies of this php file, deleted unncessary files.

I then increased security on my other sites as much as possible with various plugins, changed passwords of user accounts, changed ftp account passwords.

Is there anything I can do to make sure this doesn’t happen again though?

Or does anyone know what vulnerability this hacker exploits?
