A defacement attack is a kind of "vandalism»A website, where hackers penetrate the website and replace its content with their own messages. It is usually used to cover something bigger, in the background, and the messages may convey a political or religious message, inappropriate content, or a notice that the site has been compromised.
Content alteration is usually achieved by using SQL injection and logging into the administrator account.

A defaced website, in order to return, will have to log off in order to take the necessary recovery actions, while visitors will feel that there is not enough security and that the page is not able to be protected.
In the circle of hackers there are even online contests that highlight who will do the most defacement in a certain period of time.

Usually, such attacks are guided, and can often be combined with other types of attacks and data interception.
