As I was running Wordpress 2.2 until five minutes ago, this post at techcrunch caught my eye:

Due to its popularity as a blogging platform, Wordpress has become a prime target for hackers looking to take over blogs for search-engine optimization (SEO) of other sites they control, traffic-redirection and other purposes. Recently there have been a spate of automated attacks which take advantage of recently discovered security vulnerabilities in Wordpress.

To date, Wordpress has been keeping up with the security holes by releasing updates within a few days of new exploits being found, but in the past few days new exploits have appeared that nobody seems to have answers for.

If you are currently not running the latest version of Wordpress then there is a very high chance that your site has already been compromised.

So I quickly updated wordpress and thought that you would like to know about this.

Also, it means that my awe inspiring plug in has now been tested on two versions of wordpress!
