How Source code injection works & ways to remove it?

When you download pirated theme or plugin. the cracks leaves php backdoor,

Mostly the code in index.php.

When the user visited the website they  place ads from different ad networks. or requesting user to download a software like flash player by a popup page on your website. (incase of adsense they may change publisher id & ad code but adsense not allowed this on unverified sites.)

They download other software instead of flash player.

Scan with wordfence or other tools or edit manually all files and remove the code.

NOTE: Don’t use all Features unless you know what you doing. (less resources consumption)

adds lot of rules to your .htaccess file but it slows down your wp-admin access. maybe it slows your website performance.

the best feature is Disabling brute force attack by custom URL login page and custom keyword with string to store a cookie on your pc with a secret word. all other trying to access they will redirect where you want.

google Authenticator plugin

Add step 2 verification WordPress login: you can use google Authenticator plugin. for that you have t o install google authenticator app on mobile.

You can login with wordpress.com username & password if you installed jetpack plugin.

How to prevent WordPress brute force Attacks Login lockdown?

Login Lockdown by IP Address banning really not works for brute force attacks, because hackers use lots of ip address.

 

Don’t expose wp-login.php

Protect wp-admin directory with .htaccess password.

 

Always check the error log in WordPress directory.

Block brute force attack by XML -RPC.php

try to rename xml-rpc.php but we can get errors in access logs.  but we can protect it by .htaccess

<FilesMatch “xmlrpc.php”>
Order Deny,Allow
deny from all
</FilesMatch>

 

Block XML RPC & anonymous referees

Block No referer request by .htaccess apache

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_METHOD} POST
RewriteCond %{REQUEST_URI} .(wp-comments-post|wp-login)\.php*
RewriteCond %{HTTP_REFERER} !.*chagewithyour.com.* [OR]
RewriteCond %{HTTP_USER_AGENT} ^$
RewriteRule (.*) http://%{REMOTE_ADDR}/$1 [R=301,L]
</ifModule>

 

You can block post requests to avoid injecting malicious script.

evasis 20 apache module blocks XML RPC.php

 

ip based login — wordpress without any securing plugins

Allow login from only from your workstation if your isp provides a static ip. if dynamic IP you can add isp hostname or you can check hostname by ip address online with this word on google host to ip. or subnet mask of ip.  to know your id just do search as what is my ip.

 

add this .htaccess file

<FilesMatch “wp-login.php”>
Order Deny,Allow
deny from all
allow from 8.8.8.8
</FilesMatch>

subnet ip address are start with same address but last few digits different

Allow from dynamic ip

<FilesMatch “wp-login.php”>
Order Deny,Allow
deny from all
allow from .isp.example.com
</FilesMatch>

Limited Access to Wp-admin folder

add the same code in wp-admin .htaccess folder.

 

.htaccess password protecting wp-login.php without any wordpress security plugins

<Files ~ “^\.ht”> Order allow,deny Deny from all </Files>

<Files wp-login.php>
AuthUserFile ~/.htpasswd
AuthName “Private access”
AuthType Basic
require user green
</Files>

 

Authorization file can be located anywhere in the directory. but you have to give the exact path.

create a New file called .htpasswd and paste the htaccess password there.

you have to generate htacess password using one of many available tools like Cpanel, ssh.

USE Cloudflare and Select security level medium or high based on your requirement.
