4 Best Plugins to Scan WordPress Theme for Malicious Code

I always recommend my readers to purchase only premium themes. People ask me why buy a premium theme when you can get a free (or nulled) theme easily on the net. Using a recognized free theme from WordPress repository is fine. But, getting themes from unverified sources can cost you a lot. The answer is pretty obvious: “Possibility of malicious code in the theme files”.  This malicious code can be in the form of Trojan, botnet, link to third-party malicious sites or worse, a backdoor. The attacker using this code can potentially harm your website in a way you can not even imagine. With the increase in daily WordPress attacks, I decided to write a blog post to suggest some best plugins to scan WordPress Theme for malicious code.

Before you dive into the list of plugins, it’s important to know how this malicious code can get into your theme files in the first place.

1. Theme Authenticity Checker (TAC)

Theme authenticity checker, commonly known as TAC is one of the best WordPress plugin to scan theme files for malicious code. It 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. Although this plugin has not been updated for over 2 years, it still works well enough.

TAC also search for static links and displays the list of sites to which your theme is linking to.
