What is DNS Hijacking
0DNS hijacking or DNS redirection is the practice of redirecting the resolution of Domain Name System (DNS) names to rogue DNS servers, particularly for the practice of phishing, or to direct users’ HTTP traffic to the ISP’s own webservers where advertisements are served
Google+What is Domain Hijacking
0Domain hijacking or domain theft is the process by which registration of a currently registered domain name is transferred without the permission of its original registrant, generally by exploiting a vulnerability in the domain name registration system.
ICANN imposes a 60-day waiting period between a change in registration information and a transfer to another registrar; this is intended to make domain hijacking more difficult, since a transferred domain is much more difficult to reclaim, and it is more likely that the original registrant will discover the change in that period and alert the registrar. Extensible Provisioning Protocol is used for many TLD registries, and uses an authorization code issued exclusively to the domain registrant as a security measure to prevent unauthorized transfers.
