Longitudinal criminological studies greatly improved our understanding of the longitudinal patterns of criminality. These studies, however, focused almost exclusively on traditional types of offending and it is therefore unclear whether results are generalizable to online types of offending. This study attempted to identify the developmental trajectories of active hackers who perform web defacements. The data for this study consisted of 2,745,311 attacks performed by 66,553 hackers and reported to Zone-H between January 2010 and March 2017. Semi-parametric group-based trajectory models were used to distinguish six different groups of hackers based on the timing and frequency of their defacements. The results demonstrated some common relationships to traditional types of crime, as a small population of defacers accounted for the majority of defacements against websites. Additionally, the methods and targeting practices of defacers differed based on the frequency with which they performed defacements generally.
While traditional crime rates are decreasing, cybercrime is on the rise. As a result, the criminal justice system is increasingly dealing with criminals committing cyber-dependent crimes. However, to date there are no effective interventions to prevent recidivism in this type of offenders. Dutch authorities have developed an intervention program, called Hack_Right. Hack_Right is an alternative criminal justice program for young first-offenders of cyber-dependent crimes. In order to prevent recidivism, this program places participants in organizations where they are taught about ethical hacking, complete (technical) assignments and reflect on their offense. In this study, we have evaluated the Hack_Right program and the pilot interventions carried out thus far. By examining the program theory (program evaluation) and implementation of the intervention (process evaluation), the study adds to the scarce literature about cybercrime interventions. During the study, two qualitative research methods have been applied: 1) document analysis and 2) interviews with intervention developers, imposers, implementers and participants. In addition to the observation that the scientific basis for linking specific criminogenic factors to cybercriminals is still fragile, the article concludes that the theoretical base and program integrity of Hack_Right need to be further developed in order to adhere to principles of effective interventions.
ENGLISH: A vast and growing body of research has shown that crime tends to run in families. However, previous studies focused only on traditional crimes and research on familial risk factors for cyber offending is very scarce. To address this gap in the literature, the present study examines the criminal behavior of the family members of a sample of cyber offenders prosecuted in the Netherlands. The sample consists of 979 cyber offenders prosecuted for computer trespassing between 2001 and 2018, and two matched groups of 979 traditional offenders and 979 non-offenders. Judicial information and kinship data from Dutch Statistics were used to measure criminal behavior among family members. Both traditional offenders and cyber offenders were found to be more likely to have criminal fathers, mothers, and siblings than non-offenders. Additional analyses, however, showed different patterns between cyber offenders who were only prosecuted for cyber offenses and those who also committed traditional crimes. While the former group of cyber offenders were similar to non-offenders in terms of family offending, the latter group of cyber offenders were more similar to traditional offenders. Overall, these results suggest that the traditional mechanisms of intergenerational transmission of crime can only partially explain cybercrime involvement. NEDERLANDS: Uit een groot en groeiend aantal onderzoeken blijkt dat criminaliteit vaak in families voorkomt. Eerdere studies richtten zich echter alleen op traditionele misdrijven en onderzoek naar familiaire risicofactoren voor cybercriminaliteit is zeer schaars. Om deze leemte in de literatuur op te vullen, onderzoekt deze studie het criminele gedrag van familieleden van een steekproef van cyberdelinquenten die in Nederland worden vervolgd. De steekproef bestaat uit 979 cyberdelinquenten die tussen 2001 en 2018 zijn vervolgd voor computervredebreuk, en twee gematchte groepen van 979 traditionele delinquenten en 979 niet-delinquenten. Justitiële informatie en verwantschapsgegevens van het Centraal Bureau voor de Statistiek werden gebruikt om crimineel gedrag onder familieleden te meten. Zowel traditionele daders als cybercriminelen bleken vaker criminele vaders, moeders en broers en zussen te hebben dan niet-daders. Aanvullende analyses lieten echter verschillende patronen zien tussen cyberdelinquenten die alleen werden vervolgd voor cyberdelicten en degenen die ook traditionele delicten pleegden. Terwijl de eerste groep cyberdelinquenten vergelijkbaar was met niet-delinquenten wat betreft gezinsdelinquentie, leek de tweede groep cyberdelinquenten meer op traditionele delinquenten. In het algemeen suggereren deze resultaten dat de traditionele mechanismen van intergenerationele overdracht van criminaliteit de betrokkenheid bij cybercriminaliteit slechts gedeeltelijk kunnen verklaren.
