As is often the case, however, the short answer only tells part of the story. The whole story helps to shed a lot more light on internet security.

How is a website defaced?

Website defacements are primarily orchestrated by unskilled actors using automated applications to test vulnerabilities of websites, such as SQL injection attacks. These attacks are often opportunistic; when a probing tool is successful they will initiate an attack.

What is defacement in cyber security?

What it is. Website defacements are the unauthorized modification of web pages, including the addition, removal, or alteration of existing content.

The MCA-DRB hacker group was responsible for 5,530 website defacements across all five continents, many of them targeting government sites. In 2019, Georgia, a small European country, experienced a cyber attack in which 15,000 websites were defaced, and then knocked offline.
