I found out that my wordpress 2.32. was hacked. The index.php file on the root directory was modified and changed to permission 555, and I wasn't able to change it or delete it. Besides that, there is also a file named wp-db.inc created under wp-includes directory. I can't delete the file. Whatever changes I made will revert back to permission 555 or files being recreated. Any one has this kind of problem also ?? Help !!
P/s: i upgraded to wordpress 2.3.3 and still having same problem.
