title: My Wordpress plugins folder was hacked by placing a file that sent out spam emails how to I prevent that from happening?
body: <p>Hackers placed a file named trimite.php in our Wordpress plugins folder that sent out spam emails.  We have a hardware firewall.  We only have one Wordpress login and just a couple of plug-ins.  We have Wordfence and Security Ninja Lite installed also and usually try to keep things up to date.</p>
  
  <p>Any advice would be very helpful, this email hack has stopped a lot of servers from accepting emails from us and that isn't good because in order to register on our website we send a confirmation email.</p>
