WordPress Hacked

Hi there,

quick question to those in the know, my website was hacked recently, I was using the most recent version, before the snoopy.php update, my webhost shut down my site until the attacks stopped.

It seemed someone created a folder called /mydomain.com/ser and was using my site as a proxy so somone with an IP in Irian could look at porn….

Can someone tell me if the flaw found in the version before snoopy.php 2.6.2 was the cause – or the possible cause, as I am very worried it could be something else on wp causing it. I asked if it could be a wp plugin and host support said no…

Any ideas?
