The second annual conference on the human factor in cybercrime was organized in October 2019 in The Netherlands. During this three day small-scale conference many well-known international researchers presented their latest work on the human factor in cybercrime. The small scale of the conference enabled us to make all sessions plenary. This resulted in lively discussions of the presented research and very useful feedback for the presenters. A large selection of the presented work is included as chapters in this book. This collection of chapters represents the state of the art of research on The Human Factor in Cybercrime. All chapters are based on high quality empirical research and contain a variety of disciplines and theoretical and methodological approaches, all related to human factors in cybercrime.
