How to Detect Malicious Code in your WordPress Themes

Detect malicious code – Malicious code is everywhere. They can also infect a website, a server, or even a WordPress theme. It could be a Trojan, botnet, or, even more dangerously, a backdoor or web shell.

So it’s important to do a routine scan on your WordPress themes, especially if you get them from unknown sources (nulled?). Here is a plugin review that can help you to check WordPress for Malicious code.

How to Detect Malicious Code in WordPress Themes

Here’s how to detect malicious code in WordPress themes:

1. Theme Authenticity Checker (TAC) Plugin

TAC stands for Theme Authenticity Checker. TAC searches the source files of every installed theme for signs of malicious code. If such code is found, TAC displays the path to the theme file, the line number, and a small snippet of the suspect code.

2. Theme-Check Plugin

The theme check plugin is easy to test your theme and ensure it’s up to spec with the latest theme review standards. With it, you can run all the same automated testing tools on your theme that uses for theme submissions.

3. WP Change Tracker

WP Changes Tracker is not a malware checker. It highlights the changes that have been made to the WordPress database, plugin files, and theme files.

This plugin will keep track of all changes made to your WordPress structure: core, network, plugins, and options.

4. Wordfence Security

Wordfence is one of my favorites. It starts by checking if your site is already infected. We do a deep server-side scan of your source code, comparing it to the Official WordPress repository for core, themes, and plugins.

It’s 100% free but offers a Premium API key that gives you access to premium support and features.

5. Sucuri Online Scanner

Sucuri, one of the leading internet security firms, offers a free online scanner that checks websites for known malware, blacklisting status, website errors, and outdated software.

The scanner is available for free, but you can also choose to pay for a premium plan or feature. Sucuri’s online scanner is one of the best available and is definitely worth trying.
