1. A method for preventive filtering of network traffic data, the method comprising:
receiving historical network traffic data and a domain classification list;
generating a unique domain names list based on the historical network traffic data;
generating a bad domains list based on the unique domain names list and the domain classification list;
modifying the unique domain names list by replacing each entry of the unique domain names list that appears in the bad domains list by a common classification label; and
learning a respective vector representation for each entry of the modified unique domain names list.
