WordPress Security: Common Attacks and Defense

WordPress is the world's most popular content management system, which also means it's a favorite target for hackers. But don't panic! Most attacks can be prevented with a few basic security measures. Learn about the most common forms of attack so you know what to defend against.

1. Brute Force Attack

What is it? The attacker uses automated software to try hundreds or thousands of password combinations per second on your login interface (wp-admin) until they find the correct one. Weak, easily guessable passwords (e.g., "123456", "admin") are the most vulnerable.

Defense: Use a strong, unique password! Install a security plugin (e.g., Wordfence) that limits the number of login attempts and temporarily bans trying IP addresses. Two-factor authentication (2FA) is also essential.

2. Vulnerabilities in Outdated Software

What is it? Outdated versions of the WordPress core, themes, and plugins may contain known security holes. Hackers constantly scan the internet for such vulnerable sites.

Defense: The most important thing: update everything regularly! Keeping WordPress, themes, and plugins up to date is the most effective protection. Turn on automatic updates where possible, or entrust maintenance to a professional.

3. SQL Injection

What is it? The attacker tries to "inject" malicious SQL code through your website's forms (e.g., search, comments) to access your database, steal user data, or take control of the site.

Defense: A good security plugin (Web Application Firewall - WAF) can detect and block these malicious requests. Additionally, it is important that the website code is properly handled by the developer.

4. Cross-Site Scripting (XSS)

What is it? Similar to SQL injection, but here the attacker targets your website's visitors, not the database. They place malicious JavaScript code on your site (e.g., in a comment), which runs in other visitors' browsers and can steal their data.

Defense: A Web Application Firewall (WAF) helps here too. Additionally, it is important that your website properly "sanitizes" user-inputted data before displaying it.

Security is not a one-time setting, but an ongoing process. Regular maintenance and common sense are the best defense.
