Being the primary mechanism for users to access services on the Internet, domain names became a valuable part of any brand with an Internet presence.

We postulate that combining judiciously chosen detection tools with novel domain registration policies can make the vast majority of current malicious domain name registrations economically nonviable, and can decrea
