Abstract
A method includes receiving a set of strings and applying one or more filters to generate a subset of strings that are determined to correspond to strings of interest. The method also includes retrieving domain name system (DNS) information associated with a first string of the subset. The method includes executing a rule-based engine to determine, based on application of one or more rules to the DNS information, whether to add the first string to a set of suspicious hostnames.
