WordPress is a popular platform for building websites, but its widespread use also makes it a prime target for malicious attacks. One common issue website owners face is dealing with malicious code that can disrupt operations, steal data, and even jeopardize the trust of users. If your WordPress site has been compromised, knowing how to respond effectively is crucial to minimize damage and secure your website for the future.
How Can Malicious Code Cause Damage?
Understanding how a malicious code can cause damage to your website is the first step in protecting yourself. Malicious code is typically injected into your website by hackers through vulnerabilities in plugins, themes, or outdated software. Here are some of the ways this code can harm your site:
