1. Brute Force Attacks
WordPress brute force attacks refer to the trial and error method of entering multiple username and password combinations over and over until a successful combination is discovered. The brute force attack method exploits the simplest way to get access to your website: your WordPress login screen.
WordPress, by default, doesn’t limit login attempts, so bots can attack your WordPress login page using the brute force method. Even if a brute force attack is unsuccessful, it can still wreak havoc on your server, as login attempts can overload your system. While you’re under a brute force attack, some hosts may suspend your account, especially if you’re on a shared hosting plan, due to system overloads.
2. File Inclusion Exploits
After brute-force attacks, vulnerabilities in your WordPress website’s PHP code are the next most common security issue that can be exploited by attackers. (PHP is the code that runs your WordPress website, along with your plugins and themes.)
File inclusion exploits occur when vulnerable code is used to load remote files that allow attackers to gain access to your website. File inclusion exploits are one of the most common ways an attacker can gain access to your WordPress website’s wp-config.php file, one of the most important files in your WordPress installation.
3. SQL Injections
Your WordPress website uses a MySQL database to operate. SQL injections occur when an attacker gains access to your WordPress database and to all of your website data.
With an SQL injection, an attacker may be able to create a new admin-level user account which can then be used to login and get full access to your WordPress website. SQL injections can also be used to insert new data into your database, including links to malicious or spam websites.
4. Cross-Site Scripting (XSS)
84% of all security vulnerabilities on the entire internet are called Cross-Site Scripting or XSS attacks. Cross-Site Scripting vulnerabilities are the most common vulnerability found in WordPress plugins.
Malware, short for malicious software, is code that is used to gain unauthorized access to a website to gather sensitive data. A hacked WordPress site usually means malware has been injected into your website’s files, so if you suspect malware on your site, take a look at recently changed files.
Although there are thousands of types of malware infections on the web, WordPress is not vulnerable to all of them.
