This term is derived from the term hi jacking. In these kinds of offences the hacker gains access and control over the web site of another. He may even change the information on the site. This may be done for fulfilling political objectives or for money. E.g. recently the site of MIT (Ministry of Information Technology) was hacked by the Pakistani hackers and some obscene matter was placed therein. Further the site of Bombay crime branch was also web jacked. Another case of web jacking is that of the ‘gold fish’ case. In this case the site was hacked and the information pertaining to gold fish was changed.
