11 WordPress Plugins To Detect Malicious Code In Your Site

Being one of the most popular platforms for creating websites, WordPress has become a lucrative target for hackers and potential abusers. They apply different techniques and follow different approaches to gain access to WordPress sites. In order to prevent their attack and save your website, you need a reliable security wall.

Additionally, some WordPress users use premium themes and plugins that are downloaded by illegal means. Almost all of these pirated themes or plugins have malicious code, loopholes or backdoors installed in them. If you use any pirated theme or plugin, you are in great danger of losing control of your website, data or reputation any day.
