I am a graduate student in cybersecurity and purchased this book for research about the psychological profiling of cyber intrusion actors in the Human Aspects of Cybersecurity course I was taking. So many reformed hackers have objected to the term, "hacker," being used across the board, so the politically correct term used today is "actor." Referring to actors in the nomenclature allows for a discussion of an intrusion without needing to prematurely address cybercriminal subtypes.
This book discusses a taxonomy for profiling intrusion actors. Historically, the psychological profiling of criminals was adapted for cybercrime. Psychological profiling is not well suited to theoretical concepts since it is a practical application of psychology and cannot encompass the entire range of human functioning. For instance, Costa and McCrae's Five Factor Theory includes numerous factors tethered to personality and properties reliant on it, however, certain aspects of criminal behavior such as modus operandi are excluded. Such limitations in differing approaches exacerbate the schism that exists in profiling cybercriminals.
This book relies on the research conducted during the Hacker's Profiling Project (HPP) (which is still ongoing) that seeks to add other dimension(s) to profiling. Promoters of the HPP assert that further exploration is needed in profiling actors since such an undertaking is more multifaceted than previous models reveal. Rather than use a taxonomy that segregates actors by skills, knowledge, and motive, HPP adds both deductive methods (crime "scene" observations) and inductive methods (compiling data from biographical, questionnaires) as well as interviews of both former and current actors.
I recommend this book to anyone who is seeking to learn more about the hurdles in profiling cyberspace intrusion actors.
