WordPress sites can be vulnerable to various types of cyber attacks. Here are some common ones and how to protect against them:

File Inclusion Exploits: Attackers include malicious files in your site, often through vulnerable code. Validate and sanitize all user inputs to prevent this1.

Brute Force Attacks: Attackers try numerous username and password combinations to gain access. To protect against this, use strong, unique passwords and enable two-factor authentication1.

Cross-Site Scripting (XSS): Malicious scripts are injected into your site, which can steal user information or redirect users to harmful sites. Regularly update your plugins and themes, and use a WordPress firewall2.

SQL Injection: Attackers insert malicious SQL code into input fields, compromising your database. Use prepared statements and parameterized queries to safeguard against this2.

Malware: Malicious software can be injected into your site, often through outdated plugins or themes. Regularly scan your site for malware and keep everything updated2.

DDoS Attacks: Distributed Denial of Service attacks overwhelm your site with traffic, causing it to crash. Use a content delivery network (CDN) and a web application firewall (WAF) to mitigate these attacks1.
