Anon Coders has hacked my site. Can someone help me restore my site as it should be? I have a backup from yesterday (that I exported from my site when it was fine), but not sure, how to go about getting them out of my site and I don’t want to totally screw everything up. Advice from keeping this from happening again in the future would be appreciated. I had protection plugins installed, but they managed to get around them.
This is the discussion part of the site. Delete everything that you have on the hosting and reupload the scripts, theme, bare minimum of plugins and create a fresh database with your backup. You have backed up all your uploaded files too, right? Something on your site wasn't secure, so check your directory settings and check the plugins that you use... are they reputable?
If you still have access to FTP, download a complete backup of the hacked site as well - that way, you can go through the files and find (perhaps) the culprit, where they got in. If you have a reputable host, they should be able to do this for you. Have you upgraded all plugins and Wordpress itself whenever there is an update available? Should be checked more or less daily (although Wordpress itself will normally auto-update). As sarahk said, wipe the whole site, including database, and reupload ONLY wordpress and database - then go through the plugins you had installed, see if you need all of the, and only install those you're 100% sure you need. And if you're unsure about the quality or if any of the plugins haven't been updated in the last ~3 months, get rid of them.
