Cognitive hacking and intelligence and security informatics describes research on cognitive and semantic attacks on computer systems and their users. In the near future, It is predicted that semantic attacks will be more serious than physical or even syntactic attacks. Semantic attacks directly target the human/computer interface, the most insecure interface on the Internet. Conversation hackers and trolls also influence a lot. Predictive modeling using the concepts of cognitive hacking and utility-theoretic information retrieval can be applied in two intelligence and security informatics settings which are mirror images of each other, i.e., the user's model of the system's document content and the system's model of the user as a potential malicious insider.
