5 common WordPress security issues

[vakafx]

The goal of hackers is to gain unauthorized access to your WordPress site at the admin level, from the interface (your WordPress dashboard) or server side (by inserting malicious scripts or files ).

Here are the 5 most common WordPress security issues you should know:

1. Brute Force Attacks
BruteForce attacks refer to password detection method. Bruteforce attack is the simplest way to gain access to your site. To better understand BruteForce, you can refer to more information about Bruteforce on Wikipedia

By default, WordPress does not limit the number of wrong logins, so hackers can attack your WordPress login page with a bruteforce attack until you find the correct login information.

2. File Inclusion Exploits
After Bruteforce attacks, another PHP-related vulnerability (the source code used to write WordPress) is File Inclusion Exploits which is also the next common security issue that can be exploited by hackers.

The File Inclusion vulnerability allows hackers to gain unauthorized access to sensitive files on the web server or execute malicious files using the "include" function.

Through this vulnerability, an attacker can read the wp-config.php file and know the database connection information, thereby hijacking your website.

3. SQL Injections

Your WordPress site uses a MySQL database to work. SQL Injections occurs when an attacker gains access to your WordPress database and all your website data.

With SQL Injections, an attacker can create a new administrator user account, which can then be used to log in and gain full access to your WordPress site. SQL Injections can also be used to insert new data into your database, including links to malicious or spam websites.

SQL Injections usually happen by programmers when the theme code, plugins are wrong and do not filter data carefully before inserting them into the database.

4. Cross-Site Scripting (XSS)

84% of all internet security vulnerabilities are called Cross-Site Scripting (XSS) attacks Cross-Site Scripting vulnerability is the most common vulnerability found in WordPress plugins and themes.

The basic mechanism of Cross-Site Scripting works like this: an attacker seeks to make a victim load websites with unsafe javascript scripts. These downloaded scripts are then used to steal data from the user's browser.

5. Malware
