My blog is built up with wordpress 2.92, from the build up to now suffered two hacker attacks to modify my home, I do not know how it is, leave contact "Digital boy"
Well, Did It have some Valuable or extablished Content? I mean, Was the blog well established? If No, Simply reinstall, Make sure all things are right, And Go Safe! I recently got a Work to disinfect 5 Wordpress Sites from BUXP (thats his username Here! You can ask him about me!) His some sites were well established! So restoring posts should be done perfect making sure that there are no injections! Good Luck! ~Exp~ Want me to do it? I can, If You Pay!
Sounds like you suffered from a xss. That's the trouble with older versions of WP. They're vulnerable. http://www.google.com/search?&q=xss+wordpress+2.9
