Websites or blogs using shared hosting are more easily to get compromised rather than websites running on dedicated server. It is probably due to server configuration flaws or other few possible causes.

10. Always backup your WordPress blogs daily

Pro hackers will always find a way to break a system no matter how secure it is. However, you can always backup your WordPress database daily and restore them in case your blog database has been compromised and deleted, damaged or altered by the attackers.
