Just a heads-up for any Wordpress users. I was hit by this on the 20th of June and just found out today (although it's been out a while). I've got quite a few WP sites, so I need to check over them all, but I think it just affected one.
I'm still reading through this lot to find out how it happened and what to do to fix it fully and stop it happening again.
