A cyber security attack in which an attacker makes unauthorised changes to the content of a website. These attacks usually result in changes that are visible to visitors to the website, such as changing the address of the page, adding news or messages, or even replacing the entire content of the page. Attackers often exploit vulnerabilities such as weak passwords, poorly updated software or security flaws in the content management systems of websites.
