Abstract:
Methods for identifying potentially harmful, malicious, or unwanted content based upon associations with known offenders are provided. Executable content associated with a domain is identified. The executable content URL and the domain are compared to URLs/domains known to be associated with malicious content. If the URL and/or the domain has been identified as associated with offending code, the remaining domain contents and any available associated information are examined to identify any referencing domains, referenced domains, linking domains, affiliated entities, etc. Each identified domain, affiliate, etc. is subsequently examined in a similar manner to identify any domain, entity, etc. having an association with malicious content. Each identified domain, entity, etc. is assigned a suspicion level based upon proximity to the source of the offending code. If desired, relationships among the domains, entities, and the like may be relationally mapped to render associations easier to identify.
