If you have been a victim of WordPress defacement or hacking and have viruses or malware embedded in your site, or if you repeatedly find yourself in a similar situation, you may wonder where hackers are getting into your site.
In this article, we will explain how to find vulnerabilities in plugins and WordPress itself, which is one of the ways hackers can enter your site.

Three major methods of WordPress hacking infiltration

Hackers will use the following three main methods of infiltration in WordPress to tamper with the WordPress program

1. Capturing administrative privileges (user IDs, and passwords through brute force login attempts)

2 Intrusion from vulnerabilities in WordPress itself or plug-ins
3 Intrusion from server vulnerability

The number 2 method of targeting WordPress vulnerabilities has been increasing in recent years, and leaving vulnerabilities unchecked is considered increasingly dangerous.

How hackers find and attack vulnerable sites

There are various ways in which hackers find vulnerable sites. First, there is a method called Dork.
This method targets sites where a directory of vulnerable plugins has been picked up and indexed by search engines.
By searching the path of the vulnerable plugin in the search engine, you can easily find out which sites have the plugin.

Another method is to attack a site by using a program called MassExploit, which automatically detects dozens of vulnerabilities at once, by retrieving the URLs of WordPress sites from a collection of WordPress site links.

Check for vulnerabilities in WordPress and plug-ins

WordPress :Malware Scan & Security Plug-in [Malware and Virus Detection and Removal], developed by WordPress Doctor, will check your WordPress and plug-ins for vulnerabilities based on the vulnerabilities registered with NIST, an international organization based in the United States. WordPress and plug-ins can be checked for vulnerabilities based on the vulnerability database built by WordPress Doctor.

Once you have installed the plugin, go to the Administration page > Malware Scan > Vulnerability tab to run the vulnerability check.

The results of the scan will indicate whether or not WordPress itself and the plugin are free of dangerous vulnerabilities.
Dangerous vulnerabilities are those that allow a WordPress user to modify the site’s database or files without authentication from outside WordPress.

If a vulnerability is found, please remove or update the plugin and use the non-vulnerable version.
We recommend that you run this check every few months as the vulnerability database is updated daily.
