1. A method for determining a probability that a suspected domain name associated with a suspected domain, accessed using a universal resource locator (URL) entered as a character string into a browser associated with a client in a network environment, is a counterfeit of a legitimate domain name, the method comprising:

  • parsing a first character string entered into the browser, the first character string associated with the suspected domain name, to identify one or more predetermined characters in the suspected domain name having a known likelihood of being deceptively substituted for a corresponding one or more legitimate characters associated with the legitimate domain name;

    generating an alternate domain name by substituting at least one of the one or more predetermined characters with the corresponding one or more legitimate characters; and

    attempting to resolve an alternate domain associated with the alternate domain name,wherein if the alternate domain name is successfully resolved, a non-zero probability is assigned to the suspected domain name as being the counterfeit of the legitimate domain name.
