Website defacement
 | This article needs additional citations for verification. (December 2012) |
Website defacement is an attack on a website that changes the visual appearance of a website or a web page. These are typically the work of defacers, who break into a web server and replace the hosted website with one of their own. Defacement is generally meant as a kind of electronic graffiti and, as other forms of vandalism, is also used to spread messages by politically motivated "cyber protesters" or hacktivists[1]. Methods such as a web shell may be used to aid in website defacement.
Common targets
Religious and government sites are regularly targeted by hackers in order to display political or religious beliefs, whilst defacing the views and beliefs of others. Disturbing images and offensive phrases might be displayed in the process, as well as a signature of sorts, to show who was responsible for the defacement. Websites are not only defaced for political reasons; many defacers do it just for the thrill. For example, there are online contests in which hackers are awarded points for defacing the largest number of web sites in a specified amount of time. Corporations are also targeted more often than other websites on the World Wide Web and they often seek to take measures to protect themselves from defacement or hacking in general. Websites represent the image of a company or organisation and these are therefore suffer significant losses due to defacement. Visitors may lose faith in sites that cannot promise security and will become wary of performing online transactions. After defacement, sites have to be shut down for repairs and security review, sometimes for an extended period of time, causing expenses and loss of profit and value.
