The web installer writes configuration data into that file. It needs write access for that. I don’t think this was your backdoor. There was probably a plugin or an old theme with timthumb that had a vulnerability.
WPMU Ldap Authentication was causing the incorrect URL issue. Disabling the plugin allowed users/sites to be created correctly. This site has a fix for the plugin that allows it to run properly in WP 3.5.2: http://www.fotan.net/wpmu-ldap-plugin-fixes/
You need to have the table prefix set in the wp-config.php file. It must be matching the same value in tables of your database, the default value is “wp_” but if you used a customized value for your tables to enhance security which is a good practice, you need to update your $table_prefix = ‘wp_’; … Read more
Guess it needs to be said first – it is a bad idea in general to just let anyone that succeeded to trick you into uploading his PHP onto your server to actually be able to write to your code directories. It is double problematic if you let him access to your root credentials and … Read more

I am not aware of a WordPress function to do this. But have a look at this search and replace tool: https://interconnectit.com/products/search-and-replace-for-wordpress-databases/ This achieves what you want by reading in the wp-config file and scanning through it.

I don’t think there is a good reason to actually do this, but you can simply use what’s in your config to point to another host. Right from the codex page. define(‘DB_HOST’, ‘mysql.example.com:3307’);
I accidentally stumbled into the answer today when I forgot to turn on my MAMP managed mysql server. At this juncture it pointed me to the critical difference. This answer is phrased for anyone running MAMP but potentially has broader applicability (certainly LAMP, WAMP, etc.); if you’re experiencing the same problem in an non-MAMP environment … Read more
