Hi ! I am using the latest version of wordpress. Someone has hacked my website. I am able to access my hosting account so I changed all the passwords. But something is surprising here. DB is changed. it is having more than 30 tables whereas WordPress should have 19 tables. I tried to change the password of admin from the DB, but that didn't work for me. I haven't yet re-installed the blog because I want to understand that how someone was able to do this thing.
