US Patent 9253208 System and method for automated phishing detection rule evolution

System and method for automatically developing phishing detection rules. Based on detected phishing indicia, a quantitative score is computed for each of a plurality of predefined parameters, with each of the parameters relating to at least one of the phishing indicia. A requirement for evolving a phishing detection rule is assessed, and a new phishing detection rule is generated based on selected parameter scores meeting the rule evolution criteria and on corresponding content of the phishing indicia relating to those selected parameter scores. New phishing detection rules are applied recursively to detect phishing indicia, and more new rules can be further evolved in recursive fashion.
