Domain hijacking
Domain hijacking or domain theft is the act of changing the registration of a domain name without the permission of its original registrant, or by abuse of privileges on domain hosting and registrar software systems. This can be devastating to the original domain name holder, not only financially as they may have derived commercial income from a website hosted at the domain or conducted business through that domain's e-mail accounts, but also in terms of readership and/or audience for non-profit or artistic web addresses.
