I have had two WordPress blogs hacked into previously. That was in 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 were not eliminated, however the ratings were reduced.
Finally, fix hacked wordpress site will tell you that there is not any htaccess in the wp-admin/ directory. You may put a.htaccess file if you desire, and you can use it to control access to the wp-admin directory from IP address or address range. Details of how to do that are available on the net.
It is not unusual for blogs to be hacked by a person today. In fact, even entire domains get hacked. If you aren't a developer or Extra resources a programmer, there is not any way you will understand anything about programming languages or codes. This is the reason why some of the people who do not know anything about codes end up if there are any ways thinking.
Fortunately, keeping your WordPress website up-to-date is one of the most easy things you can do. For the last few versions, WordPress has included the ability to set up updates. A new update becomes available.
You can even get an SSL Encyption Security to your WordPress blogs. The SSL Security makes secure and encrypted communications with your blog. You may even keep history of communication and the all the cookies so that all transactions are recorded. Make sure that all your sites get SSL security for protection from hackers.
However, I advise that you set up the Login LockDown plugin in place of any.htaccess controls. From being permitted after three failed login attempts from a certain IP address for one hour, login requests will stop. You may get into your panel whilst and yet you still have good protection against hackers if you do that.
