Hello friends, My wordpress blog got hacked by paki hacker. If anyone can help me please let me know what should I do now. PM me or post here. thanks
first thing I think you should do is contact your host provider. Before doing so backup your WordPress mysql in cpanel first, if it hasn't got hack yet... http://codex.wordpress.org/Backing_Up_Your_Database Backup your theme also if you need to. http://johnlamansky.com/wordpress/backup-theme/
Can you access the admin dashboard? He likely just "defaced" it, try to reupload your theme files, and then change your admin pass and update Wordpress to the latest version.
If you haven't any option. Final solution is restore the back up that you have saved in your PC/remote server which is backed up before the hack. But you must change its administrator password to avoid being hacked again. Also you can get the necessary support from the web hosting provider.
