A hacker has been targeting many SEO sites and has already successfully taken over many of them, including WolfHowl and Stuntdubl. I first noticed this on WolfHowl’s blog and I though it might be some sort of sneaky linkbait, but it seems to be legitimate. Here is the Hacker’s blog with his plan: http://fuckingpirate.wordpress.com/ (I won’t give him a link).
One of the tricks he was using was a WordPress security problem, which has since been fixed in version 2.0.7. If you use WordPress, I would recommend updating now. (Which I am about to do, hopefully this blog will survive the upgrade.)
There is a DigitalPoint thread on this topic.
Update: WordPress.com has now taken the hackers blog offline. Also, I successfully updated to WordPress 2.0.7
