Website defacement
is an attack on a website that changes the visual appearance of the site or a webpage. These are typically the work of system crackers, 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, although recently it has become a means to spread messages by politically motivated "cyber protesters" or hacktivists.
Common methods
The most common method of defacement is using SQL injections which allows gaining administrative access. Another method of defacement is through FTP once the username and password are obtained.
Defacements usually consist of an entire page. This page usually includes the defacer's pseudonym or "Hacking Codename." Sometimes, the Website Defacer makes fun of the system administrator for failing to maintain server security. Most times, the defacement is harmless and is only done to show off a system cracker's skills or for Hacktivism; however it can sometimes be used as a distraction to cover up more sinister actions such as uploading malware or deleting essential files from the server.
Common targets of defacement
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 sites on the Internet
and they often seek to take measures to protect themselves from
defacement or hacking in general. Web sites 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, sometimes for
an extended period of time, causing expenses and loss of profit and
value.
