With this plugin you can easily adjust your file permissions on Rackspace Cloud Sites hosting for a more secure installation. You can remove write permissions, and then revert when needed to allow upgrading, theme and plugin installation. Also includes a few extra tools to look for and eliminate other common exploits in the cloud, looking for hidden php files, non-core files, modified core files, auto loading options with malicious code, and posts/pages injected with javascript.

Apologies for the rough edges, but it's getting the job done. More to come.

PS - This plugin is for Rackspace Cloud Sites, do not use elsewhere.

Many thanks to donncha, duck_, ryan, azaozz, tott - authors of Exploit Scanner (http://wordpress.org/extend/plugins/exploit-scanner/) - for the file hashes.
