WordPress Malware: The Most Common Infections We See in 2026

Common WordPress Malware Types in 2026

1. JavaScript Injection

Attackers inject malicious JavaScript into your theme files or database. This code runs in visitors’ browsers and can steal credentials, redirect to phishing sites, or mine cryptocurrency.

2. PHP Backdoors

Hidden PHP files that give attackers remote access. Common filenames include wp-tmp.php, wp-feed.php, or files with base64-encoded code.

3. SEO Spam Injection

Hidden links and pages injected into your site to boost the attacker’s search rankings. Often targets pharmaceutical, gambling, or adult content keywords.

4. Database Malware

Malicious code stored in WordPress post content, options table, or widget areas. Harder to detect because it lives in the database, not in files.

5. Redirect Chains

Your visitors are redirected through a series of URLs before landing on a malicious site. Often triggered only for mobile users or specific search engine referrers to avoid detection.
