I've had two WordPress blogs hacked into previously. That was at a time when I was doing virtually no internet advertising, and until I found time to handle the situation (weeks later), these sites were penalized in the major search engines. They weren't eliminated, however the ratings were reduced.
I back my blogs frequently using a plugin WP DB Backup up. If anything happens I will restore my website to the last settings. I use my site to be scanned by WP Security Scan plugin that is free regularly and requests that are suspicious-looking to be blocked by WordPress Firewall to how to fix hacked wordpress.
You can search. If your site is hacked by hackers, you can easily restore your website by find more info means of your files and change everything that has to be changed.
This is quite useful plugin, protecting you against brute-force password-crack strikes. It keeps track of the IP address of every failed login attempt. You can configure the plugin to disable login Get More Info attempts when a certain number of failed attempts is reached.
Note that you should try this step for new installations. If you would like to do it for existing installations, you have to change the table names within the database.
However, I recommend that you install the Login LockDown plugin in place of any.htaccess controls. From being allowed after three failed login attempts from a specific IP address for an hour, login requests will stop. You can access your admin panel while and yet you still have good protection against hackers if you do that.
