Abstract
Embodiments of the present invention provide a method and system for determining a probability that a suspected domain name of a domain accessed using a universal resource locator (URL), which can be entered as a character string into a browser associated with a client in a net environment, is a counterfeit of a legitimate domain name. Characters in the suspected domain name can be identified as known as likely to be deceptively substituted for corresponding legitimate characters of a legitimate domain name. An alternate domain name is generated by substituting predetermined characters with the corresponding legitimate characters. An attempt can be made to resolve alternate domains of the alternate domain names. If the names are successfully resolved, a non-zero probability is assigned to the suspected domain name as being counterfeit.
