Een risico voor hacken en persoonsgerichte cyberdelicten?

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2013
Trefwoorden cybercrime, victimization, hacking, cyber stalking, cyber threats
Auteurs Jurjen Jansen MSc, Rutger Leukfeldt MSc, Dr. Johan van Wilsem e.a.
SamenvattingAuteursinformatie

    The number of Internet users who reported they have come into contact with cybercrime is substantial. This article examines three forms of cybercrime, namely: hacking, cyber stalking and cyber threats. Because cybercrime is relatively extensive in the life of Dutch citizens, it is important to gain insight into factors that influence victimization. By means of a secondary analysis of data from the first Dutch national cybercrime victim survey (N=9,161), it is assessed to which extend online behaviours affect victimization. In particular, online behaviours involving the use of communication applications affect victimization of the three aforementioned cybercrimes. The article provides suggestions for further research into cybercrime victimization.

Financiële schade bij slachtoffers van onterechte bankafschrijvingen

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2013
Trefwoorden unauthorized cash withdrawal, bank account, identity fraud, financial damage
Auteurs Dr. Johan van Wilsem, Dr. Nicole van der Meulen en Dr. Maarten Kunst
SamenvattingAuteursinformatie

    Identity fraud is a rapidly growing problem, as shown by recent volume estimates from victim surveys. Little is known however about the amount of financial damage among victims of this crime, especially in the Dutch context. This article studies victims of unauthorized cash withdrawal from their bank account, which is one of the most common forms of identity fraud. For this, we use data on 180 victims from the representative LISS panel. The results show that the financial implications of this type of crime experience vary widely between victims. While many victims are disadvantaged for only a small amount of money (for almost 40 per cent is about less than 50 euros ), a quarter of this group suffers from substantial money loss of more than 500 euros. Nevertheless, the vast majority (85 per cent) are completely reimbursed by their banks. Eventually, only in rare cases victims suffer significant permanent money loss. Remarkably, the low educated are significantly less often reimbursed by their banks.

De wegen die werknemers bewandelen bij verschillende typen misstanden op het werk

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2012
Trefwoorden whistle-blowing, safety, employee, report, wrongdoing
Auteurs Doris van van Dijk, Marijke Malsch, Gezinus Wolters e.a.
SamenvattingAuteursinformatie

    In the Netherlands whistle-blowing regulations are still unbalanced and ineffective in the protection of whistle-blowers and the prevention of misconduct at work. This article focuses on the question how whistle-blowing behaviour is influenced by the type and severity of the wrongdoing. The study also examines to whom employees would report (internally and/or externally), if they would report anonymously, and why they would do that or not. As far as the authors know, this is one of the first studies on whistle-blowing behaviour that systematically investigates the characteristics of the wrongdoing by using vignettes. In a two by two design, two kinds of wrongdoing (safety problem or embezzlement) at two levels of severity are plotted against each other. When confronted with severe wrongdoing, respondents intend to blow the whistle more often (externally) than with mild wrongdoing. Of the four cases, the difference between mild and severe embezzlement is most pronounced. Internally, a difference is found between the vignettes in reporting anonymously. Most respondents prefer to report to their direct supervisor, especially when a mild safety problem occurs. With severe embezzlement however, respondents prefer to report to a confidential adviser within the company. Outside the company, reporting to one’s trade union is most popular. Nearly all respondents would only report externally after an internal report has not yielded any results, or they would not report outside the company at all. They often argue that it is an internal problem and that the company could be harmed if the wrongdoing would be disclosed. This argument is used in all vignettes. Anonymity is still considered important by the majority of the respondents. It is recommended in this article that policymakers specify whistle-blowing regulations that are adaptable to the specific characteristics of the wrongdoing and the reporting employee(s).

Access_open Aan tafel met André Köbben

Tijdschrift Tijdschrift over Cultuur & Criminaliteit, Aflevering 2 2012
Trefwoorden André J.F. Köbben, primitive law, reseach ethics, scientific fraud, ethnographic research
Auteurs Lodewijk Brunt
SamenvattingAuteursinformatie

    André Köbben’s academic career spans sixty years and he’s still going strong – just because he likes it so much. Doing research by himself, which took him for longer periods to Ivory Coast and Surinam apart from studying conflicts in the Netherlands, but also analysing research by others. He has always been interested in questions of ‘rule’ and ‘reality’: the discrepancy between what people say they do and what they actually are doing. He probed tribal disputes among the Agni, the Bete and the Djoeka, but also conflicting interests between managers ordering research and researchers producing unwelcome results. He is preparing a book on academic fraud.

Slachtofferschap van cybercrime in kaart gebracht

Hacken, e-fraude, identiteitsfraude en voorschotfraude

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2012
Trefwoorden cybercrime, hacking, online fraud, identity fraud, victim survey
Auteurs Miranda Domenie, Rutger Leukfeldt, Johan van Wilsem e.a.
SamenvattingAuteursinformatie

    This article discusses the results of a Dutch study that focuses specifically on victimization of various forms of cybercrimes among civilians. The survey addresses the cybercrimes hacking, fraud through selling and auction websites, identity theft and fraud and advanced fee fraud. The results are based on a validated questionnaire which was posted amongst a representative sample of 21,800 citizens, the response rate was 10,314 (47 per cent). In this article of each of these cybercrimes the prevalence is shown. Concerning prevalence, the victim survey shows that in the twelve months preceding the survey 4.3 percent of all Internet users were victims of hacking, 2.4 percent were victims of online scams (by paying for a good or service but not receiving them), 0.8 percent were victims of identity fraud and 0.2 percent of advanced fee fraude. Of all victims, 11.9 percent was victim of more than one of the cybercrimes we studied for this article. If we compare this with figures of offline crime we see that in the Netherlands in 2010, 1 percent were victims of assault, 1.2 percent of burglary and 1.5 percent of sexual offenses. In comparison with these offline crimes, the cybercrimes in our study have significant numbers of victims. Among Internet users, we see that victims of hacking and fraud by auction or selling sites are more often youngsters than older people (for hacking 15 till 35 years in fraud 15 till 25 years), people without a partner are at higher risk than people with partners and people with indicated that their most recently completed education were low are more at risk than people with high education. Especially with the online fraud this is remarkable, because it appears that people who make the most purchases over the Internet are higher educated and mostly in 25 till 45 years old.

Gewone beroepen en georganiseerde criminaliteit

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2011
Trefwoorden organized crime, occupations, opportunity, concealment
Auteurs Henk van de Bunt, Krista Huisman en Karin van Wingerde
SamenvattingAuteursinformatie

    There is a large – and still growing – body of criminological literature on the relationship between crime and work. However, the exact nature of that relationship often remains diffuse. In this article we explored the relationships between organized crime and work. Based on analysis of the forty most recent cases of the Organized Crime Monitor we distinguished between two types of relations connecting organized crime and work. First, crimes can be based in the occupation of the offender when the occupation provides concrete opportunities to offend or facilitates the crimes of others. Secondly, the occupation of the offender can also be used as a shield concealing the illegal behavior or identity of the offender.

Vrouwen en witteboordencriminaliteit

Theorieën en hypothesen over sekseverschil

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2010
Trefwoorden Gender, Witteboordencriminaliteit, Vrouwelijke delinquenten, Feminisme
Auteurs Wim Huisman
SamenvattingAuteursinformatie

    White-collar crime is mostly committed by men. It remains to be seen if this will stay this way. Increasing numbers of women succeed in attaining management positions in organizations. Could we therefore expect an increase in female white-collar crime?Criminological theories on female crime and on white-collar crime lead to contradicting hypotheses.Research on white-collar and organizational crime predominantly produces a situational hypothesis explanation according to which we could expect that the rise of women in organizational hierarchies will also bring more female white-collar crime.Research on female delinquency might lead to an opposite gender-difference hypothesis that would predict less white-collar crime, because they have a lesser tendency to show risky behavior.In this article, both assumptions will be elaborated for further research, against the background of possible gender bias in the relation between women and white-collar crime.

Slachtofferschap van online oplichting nader onderzocht

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2010
Trefwoorden Online oplichting, Slachtofferschap, Slachtofferenquête, Lage zelfcontrole
Auteurs Johan van Wilsem
SamenvattingAuteursinformatie

    Consumer fraud seems to be widespread, yet little research is devoted to understanding why certain social groups are more vulnerable to this type of victimization than others. The present paper deals with internet consumer fraud victimization, and uses an explanatory model that combines insights from self control theory and routine activity theory. The results from large-scale victimization survey data among the Dutch general population (N=6,201) reveal that people with low self-control run substantially higher victimization risk, as well as people performing ‘risky’ routine activities, such as online shopping and participation in online forums. Though a minority share of the self-control-victimization link is indirect – because people with low self-control are more involved in risk-enhancing routine activities – a large direct effect on internet fraud victimization remains. This suggests that, within similar situations, people with poor impulse control respond differently to deceptive online commercial offers.

De stilte rondom Madoff

Tijdschrift Tijdschrift voor Criminologie, Aflevering 1 2010
Trefwoorden Fraude, Madoff, Oplichting, Verenigde Staten
Auteurs Prof. dr. Henk van de Bunt
SamenvattingAuteursinformatie

    This article focuses on the Madoff case which came to light at the end of 2008. Remarkable for this case is that Madoff could go on with his scam for a very long time. Failing supervision was not the only reason for this. Madoff’s qualities – disguising the illegal activities and his social stature – cannot explain the whole puzzle. The social network, a ‘secret society’ and the fact that people involved went on with it, even when knowing that ‘it was too good to be true’ are explained in this article.

De rol van de Nederlandse overheid in het blokkeren van kinderpornografische websites

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2009
Trefwoorden filteren, internet, kinderporno, politie
Auteurs Rutger Leukfeldt, Wouter Stol, Rik Kaspersen e.a.
SamenvattingAuteursinformatie

    The distribution of child pornography on the internet is observed as a major social problem. In the Netherlands a lively political-social discussion has emerged concerning the manner in which this can be prevented. The discussion moves between two polarities. On the one hand the dangers of internet censure are emphasised and on the other hand the need for a clamp down in which every measure seems to be justified. The present government wants to combat child pornography and by doing so answer the moral indignation of society. A means that the Dutch government, and on her behalf the police, uses, is blocking websites with child-pornographic content. The possibilities of the Dutch government to filter effectively, however, are restricted. The accuracy of existing filters is low and it is easy to get around filters. In addition, opportunities are restricted by constitutional rights. A filter that stops all websites with child pornography is bound to stop legal internet traffic too. That is at odds with the constitutional rights of freedom of expression and freedom of information gathering. The realisation of a filter that respects fundamental rights and still is able to block child pornography requires a lot of police manpower. This comes at the expense of the tracking down of criminals who produce and distribute child pornography. Furthermore, it is unknown whether the use of the child-pornography filter leads to the purposes for which they are deployed, such as hindering the sale of child pornography or reducing the abuse of children. The police, therefore, is assigned to a task that requires a considerable amount of time, but the benefits of which are unclear.
