I am a full professor of Cyber Security and Business Continuity at the University of Twente. I started my career at the Research and Documentation Centre (WODC) of the Ministry of Justice in 1981. I worked as a Senior Researcher at the Netherlands Institute for the Study of Criminality and Law Enforcement (NSCR – in Leiden) (1992-2000) and as an Associate professor at the Department Developmental Psychology - Utrecht University (2002-2008). I am a member of the Scientific Advisory Council (WAR) of the Dutch Defense Academy.  I founded the Crime Science journal together with Pieter Hartel and was an associate-editor for 6 years (https://crimesciencejournal.springeropen.com/).

My research interests are in the field of (online) crime, fraud and aggression and various forms of (online) fraud risk behavior. My aim is to improve prevention and provide tools for law enforcement. Together with colleagues I work to develop interventions that will help to protect users against social engineering, crime victimization and to increase compliance. 

My present research investigates the human factors of fraud and of cybercrime, more specifically in victimization, fraud, online disclosure and privacy issues. Why do users trust phishing emails or fraudsters?  Why do they comply or not comply to safety rules, why do they disclose so easily personal information and how can they be helped to become more vigilant users in order to protect themselves?

Current projects

Looking at DDoS and Phishing

Aim: We study phishing campaigns and DDoS attacks in a first attempt to investigate whether there are relationships between these two phenomena. Collaboration: Team Hight-Tech Crime and the FraudHelpDesk Funding provided by Politie en Wetenschap Principal Investigator: M. Junger Together with Abhishta Start: January 2018

Nudging and Improved Form Design (NIFOD)

The aim of this study is to improve information quality on manure that farmers provide to the Ministry of Economic Affairs and Climate Policy, via a so called ‘Aanvullende gegevens’ digital form. In the present study we propose a client-centred approach that focuses on prevention. It has two broad objectives: 1. Simplification and improvement of the form. The ‘Aanvullende gegevens’ digital form is somewhat complicated. A set of studies on how the form is filled out by farmers will lead to suggestions for form improvement. 2. Improvement of information quality. In a second part of the study we aim to improve the quality and veracity of the information. To increase honest behavior by farmers (or their representatives) when filling in the form, we will develop persuasive nudges (primes) that will increase honest reporting and decrease intentional fraud. Funding provided by Ministry of Economic Affairs and Climate Policy, RVO Principal Investigator: M. Junger Together with dr Joris van Hoof and Dr Erik Tews Start: January 2018
