WordPress Under Attack, Upgrade To 2.8.4 ASAP

wordpress-attackStatutory Warning : If you have not upgraded your WordPress hosted blog to version 2.8.4 then do it right away. WordPress versions below 2.7 are highly venerable to this attack. Matt Mullenweg founder of Wordpress has responded in the WordPress Blog saying

“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.”

How to check whether your blog is attacked ?

1). Addition of keywords like “eval” and “base64_decode” in your permalinks.

2). An additional Administrator is created. Check your dashboard for an unknow user.
