By announcing to the world the version of Wordpress you are running, you greatly simplify the work of a hacker. Peter Westwood’s post documents how to suppress output of the Wordpress version number in feeds and blog posts. I’ve packaged his code in a very rudimentary Wordpress plugin which will hide the version number in blog and rss feeds. The plugin only suppresses the Wordpress version information automatically inserted by Wordpress 2.4+.
You may still need to remove any hard coded version information in your theme. Look for a line like this:
<meta name="generator" content="WordPress <?php bloginfo('version'); ?>" /> <!-- leave this for stats -->
and remove it.
Installation:
- Download the plugin
- Unzip it to your plugins directory
- Activate it
Use at your own risk.
