Wordpress and its 64 million blogs are currently under attack by a botnet 'tens of thousands' of computers strong.
Your many and varied musings on the world around you are most at risk if you've kept your Wordpress blog username as 'admin', as the botnet is tirelessly trying thousands of possible passwords to get in and mess things up.

He also recommends using two-factor authentication if you're using WP.com, as well as making sure you're on the latest version of WordPress.
