High tech crime, high intellectual crime? Comparing the intellectual capabilities of cybercriminals, traditional criminals and non-criminals
In our highly digitalized society, cybercrime has become a common crime. However, because research into cybercriminals is in its infancy, our knowledge about cybercriminals is still limited. One of the main considerations is whether cybercriminals have higher intellectual capabilities than traditional criminals or even the general population. Although criminological studies clearly show that traditional criminals have lower intellectual capabilit…
Repeat victimization by website defacement
Repeat victimization has been widely studied from the perspective of environmental criminology for several decades. During this period, criminologists have identified a set of repeat victimization premises that are observed for many crimes; however, it is unknown whether these premises are also valid for cybercrime. In this study we rely on more than 9 million Zone-H data records from 2010 to 2017 to test whether these premises apply for the cybe…
The Hybridization of Street Offending in the Netherlands
Based on the results of two research projects from the Netherlands, this paper explores how street-oriented persons adapt and use digital technologies by focussing on the changing commission of instrumental, economically motivated, street crime. Our findings show how social media are used by street offenders to facilitate or improve parts of the crime script of already existing criminal activities but also how street offenders are engaging in cri…
Cybercriminal Networks, Social Ties and Online Forums
To gain insight into these questions, we analysed 18 criminal investigations into phishing and malware networks and developed four models of growth. Social ties still play an important role in the origin and growth of the majority of networks. Forums, however, also play a significant role in a number of networks, for example, to find suitable co-offenders or to get into contact with enablers. Criminals with access to forums are able to increase c…
Child pornography, the Internet and juvenile suspects
An example of a recurrent issue in communities is the legal system's struggle to process problems of young offenders. The main focus of this article is juvenile suspects of crimes considering child pornography. Two topics are discussed: the nature of these crimes and the characteristics of suspects. An analysis of 159 Dutch police files on child pornography shows that almost a quarter of the suspects are under 24 years of age. Of that group, 35% …
