I am not doing anything to my wordpress site but the disk space usage shown in the cPanel is growing simultaneously, growing hour by hour. (my site is 2xxmb in size for a long time, because each blog is about 3 mb to 5 mb, But the site was 3xxmb last night and is >440mb at this moment)
The stuff which is growing are:
1. MySQL database (from about 15mb to 60mb)
2. this directory: ".cagefs"
What should I do, I think I maybe hacked.
