When your WordPress website gets hacked for the second time, it’s normally because of a backdoor created by the hacker. This backdoor allows hackers to bypass the regular procedures for getting into your website, getting authentication without you figuring it out. In this newsletter, I’ll explain how to discover the backdoor and fix it on your WordPress website.
So, what’s a backdoor?
A “backdoor” is a term referring to the method of bypassing normal authentication to get into your website, thereby gaining access to your web page remotely without you even realizing it.

Others have an entire person interface (a “UI”) that offers them the potential to send emails from your server, create SQL queries, and many others.
Where is the backdoor located?
For WordPress websites, backdoors are usually placed in the following places:

Because you’ll not often ever take a look at through all of these folders, you wouldn’t discover the suspicious malware.
4. Wp-config.Php File –
This is one of the default files hooked up with WordPress. It’s one of the first places to appearance whilst you’ve had an assault, as it’s one of the most, not unusual documents to be hit using hackers.
5. The Includes folder –
Yet another commonplace listing because it’s routinely installed with WordPress; however, who checks this folder regularly?
Hackers also occasionally plant backups of their backdoors. So while you can get easily out one backdoor… There can be others dwelling on your server, nested away thoroughly in a listing you by no means observed. Smart hackers also hide the backdoor to seem like a normal WordPress record.
