WordPress Blog: How to Keep WordPress Secure
[Posted September 6, 2009 by corbet]
Here's
an entry on the WordPress Blog on keeping installations secure - a topic WordPress administrators should be especially concerned about at the moment. "
Right now there is a worm making its way around old, unpatched versions of WordPress. This particular worm, like many before it, is clever: it registers a user, uses a security bug (fixed earlier in the year) to allow evaluated code to be executed through the permalink structure, makes itself an admin, then uses JavaScript to hide itself when you look at users page, attempts to clean up after itself, then goes quiet so you never notice while it inserts hidden spam and malware into your old posts."
