WordPress users can use a free scan tool to find these codes like SiteCheck. We will go through some of the ways you can prevent these in our WordPress security steps further below.
2. Cross-Site Scripting (XSS)
84% of all security vulnerabilities on the internet are known as Cross-Site Scripting (XSS) attacks. Cross-Site Scripting Vulnerability is the most common vulnerability found in WordPress plugins and themes.
3. Denial of Service Attacks
Probably the most dangerous of all current threats, ddos exploits bugs and fixes in the code to take up all the system memory. Hackers work with millions of websites and take millions of dollars from exploiting outdated versions of wordpress with ddos attacks. Although they are less susceptible to attacks on small sites, they are used to mobilize attacks on large enterprise sites.
Even if you have used the latest version of wordpress, it is not certain that you will avoid ddos attacks, but you will be able to limit or avoid being used to participate in attacks by financial institutions and cybercrime.
4. Website infected with malicious code
One of the most common website security errors is an Injection vulnerability, also known as a malicious website call. This is an error that occurs when the input data is not carefully filtered, leading to malicious code that can “hide” into the server.
These malicious codes can leak website data or take control of the website. The simplest way to prevent this website security error is to check the input data source, check the SQL query process and protect the server using the framework.
5. Brute Force Attacks
Brute-force – Attempts to login admin page by trying multiple passwords is how attackers try to login using scripts to exploit weak passwords and gain access to your webstei. Two-factor authentication, access restriction, unauthorized access monitoring, IP blocking, and strong passwords are some of the easiest and most effective ways to prevent brute-force attacks. According to statistics, users often ignore this problem, on average, more than 30000 websites are attacked by this method a day.
6. Pharma Hacks
Pharma Hacks exploit by inserting fake codes into your wordpress sites or old version plugins, because when searching on search engines it will return an ad for pharmaceutical products on one page. web from search results that have been compromised. This vulnerability is often more dangerous than traditional malicious spam threats, once a website is infected search engines will block these websites and report them as spam.
7. File Inclusion Exploits
Another vulnerability related to PHP (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 a 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 taking control of your website.
8. SQL Injections
Your WordPress site uses a MySQL database to function. SQL Injections happen when an attacker gains access to your WordPress database and all your website data.
With SQL Injections, an attacker can create a new admin-level 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 often occur due to programmers when the theme code, plugins have errors and do not carefully filter the data before inserting them into the database.
