Background for this topic.
Defacement is a cyberattack where an attacker gains unauthorized access to a website and alters its visible content, often replacing original pages with messages, images, or propaganda. This attack targets vulnerabilities in web servers, content management systems, or web applications to modify web pages without permission.
Defacement poses risks beyond visual disruption: it can damage an organization’s reputation, erode user trust, and sometimes mask deeper intrusions like data theft. Defending against defacement requires timely patching of web software, restricting administrative access, and monitoring for unauthorized changes using file integrity tools or web application firewalls to detect and prevent unauthorized content modifications.
