After your last post on this subject, I was thinking that it would be a good idea for Automattic to create a plugin that carries out all the checks you suggested people do to find out if they’ve been hacked…
At the time I wasn’t too optimistic about it but after thinking about the idea for a few days I came up with the WordPress Exploit Scanner which does most of what Donnacha wanted.
This WordPress plugin searches the files on your site for a few known strings sometimes used by hackers, and lists them with code fragments taken from the files. It also makes a few checks of the database, looking at the active_plugins blog option, the comments table, and the posts table.
It also allows the blog owner to search for whatever string they like which could come in handy when new exploit code is used in a hack.
You must be running WordPress 2.5.1 or higher to use this plugin. There’s not much point in finding exploited files if you’re running an old version of the software that can be broken into again.
Download the plugin from here: WordPress Exploit Scanner
Thanks to those who tested the plugin, especially Cathal Garvey who provided some great feedback!
