Hacked

[baldidiot]

I had a site (not wordpress) taken down repeatedly a couple of weeks ago - still no idea how they were doing it.

Nothing like a good hacking to get you to go through and back up/update all your sites!

You can protect against manual SQL insert with this:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_METHOD} ^(HEAD|TRACE|DELETE|TRACK) [NC]
RewriteRule ^(.*)$ - [F,L]
RewriteCond %{QUERY_STRING} \.\.\/ [NC,OR]
RewriteCond %{QUERY_STRING} boot\.ini [NC,OR]
RewriteCond %{QUERY_STRING} tag\= [NC,OR]
RewriteCond %{QUERY_STRING} ftp\: [NC,OR]
RewriteCond %{QUERY_STRING} http\: [NC,OR]
RewriteCond %{QUERY_STRING} https\: [NC,OR]
RewriteCond %{QUERY_STRING} (\<|%3C).*script.*(\>|%3E) [NC,OR]
RewriteCond %{QUERY_STRING} mosConfig_[a-zA-Z_]{1,21}(=|%3D) [NC,OR]
RewriteCond %{QUERY_STRING} base64_encode.*\(.*\) [NC,OR]
RewriteCond %{QUERY_STRING} ^.*(\[|\]|\(|\)|<|>|ê|"|;|\?|\*|=$).* [NC,OR]
RewriteCond %{QUERY_STRING} ^.*("|'|<|>|\|{||).* [NC,OR]
RewriteCond %{QUERY_STRING} ^.*(%24&x).* [NC,OR]
RewriteCond %{QUERY_STRING} ^.*(%0|%A|%B|%C|%D|%E|%F|127\.0).* [NC,OR]
RewriteCond %{QUERY_STRING} ^.*(globals|encode|localhost|loopback).* [NC,OR]
RewriteCond %{QUERY_STRING} ^.*(request|select|insert|union|declare).* [NC]
RewriteCond %{HTTP_COOKIE} !^.*wordpress_logged_in_.*$
RewriteRule ^(.*)$ - [F,L]
</IfModule>

I also just found out that Wordpress will still work even if you move the wp-config.php one lebel ABOVE the root, so put it outside the publically accessible webspace on your server.

So instead of:

~/home/user/public_html/wp-config.php

Simply FTP into your server, and then move wp-config.php above the public_html directory so that it is located in:

~/home/user/wp-config.php

Another good defensive strategy: don't host a Wordpress-powered site on a server that also has other critical sites on it. That way, if they hack Wordpress only that site will get taken down.

There's a lot of debate though with this about whether it's more or less secure to move the config file a folder above.

Can't see it'd make a whole lot of difference in the grand scheme of things myself.

I can't see that making a difference, I'm looking into implementing a open_basedir for each install, more to limit php to the root of the install so it can hopefully contain an infection from spreading.

Amazing how many sites are hacked and used by spammers and people don't even realise:

Google reveals tons of others.
