Persoonlijkheidskenmerken van e-fraudeslachtoffers

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1-2 2018
Trefwoorden Online fraud, Big Five personality traits, Phishing, online marketplace fraud, cybercrime prevention
Auteurs Jildau Borwell, Jurjen Jansen en Wouter Stol
SamenvattingAuteursinformatie

    With the digitization of society, perpetrators gained new tools to commit crimes. Online fraud, also referred to as e-fraud, is one of the most common types of cybercrime. The present study focusses on two types of e-fraud: phishing and online consumer fraud. Although e-fraud always contains a digital component, the human is the weakest link in such crimes. Perpetrators deceive their victims to acquire sensitive data or to conclude a fraudulent sale, which makes victims unwillingly participate in the offence. However, not every person adheres to such fraudulent schemes. This raises the question what makes some people comply with these schemes and thus become a victim of cybercrime, while others do not. In this study, the differences between personality traits of e-fraud victims and the Dutch population were investigated. Personality traits influence the way people process information and react to situations, which also applies when people are confronted with e-fraud. Data were collected through an online survey, in which 224 e-fraud victims participated. The outcomes of the survey were compared with norm groups representative for the Dutch population. E-fraud victims, compared to the Dutch population, scored higher on extraversion, altruism and conscientiousness, and lower on neuroticism. Based on the findings, recommendations have been made for the development of targeted preventive measures against e-fraud.

Determinanten en motivaties voor intentie tot aangifte na slachtofferschap van cybercrime

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1-2 2018
Trefwoorden Cybercriminaliteit, Slachtofferschap, Aangiftebereidheid, Politie
Auteurs Lisanne Jong, Rutger Leukfeldt en Steve van de Weijer
SamenvattingAuteursinformatie

    This study focusses on determinants of willingness to report cybercrime to the police or to other organizations and motivations for (not) reporting victimization. In this study, a questionnaire containing vignettes is used. Vignettes are semi-experimental designs in which hypothetical situations are presented and certain factors can be manipulated between and within respondents. Factors that are measured within the vignettes are the type and seriousness of the offence, the relationship between offender and victim and which possibilities for reporting the offence are available.
    It is shown that the type of offence is an important determinant for willingness to report the offence, which is highest for fraud, followed by hacking and malware. Likewise, willingness to report is higher for more serious offences than for less serious offences. These results are comparable to results on willingness to report traditional crimes.
    With regard to psychological determinants, results are not in line with previous results on willingness to report traditional crimes. For the relationship between offender and victim, mixed results are found. If the offender is an acquaintance of the victim, willingness to report to the police increases, but willingness to report to another organization decreases, compared to the offender being unfamiliar to the victim. Another surprising result is that no correlation is found between attitudes towards the police and willingness to report offences. Also unexpectedly, it is found that respondents who have previously reported crime and were unsatisfied about this experience, were more willing to report offences than respondents who never reported crimes before.
    Regarding motivations for willingness to report, it is found that, in general, motivations for reporting cybercrime are strongly comparable to motivations for reporting traditional crime, however, differences in motivations are found between the different types of cybercrime.

Internetbankieren: veiligheidspercepties van gebruikers

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1 2017
Trefwoorden Risicoperceptie, Online bankfraude, Slachtofferschap, Informatiebeveiliging
Auteurs Jurjen Jansen, Nicolien Kop en Wouter Stol
SamenvattingAuteursinformatie

    In today’s society, full use is made of online banking. This makes safety and security of online banking an important issue. Two significant threats to users of online banking in The Netherlands are phishing and malware attacks. In this study, an end-user perspective is adopted to study customers’ perceptions regarding safety and security of online banking. A unique feature to this study is that we explore – besides other predictor variables – the relationship between online banking fraud victimization and risk perception. We have made a distinction between three types of victimization: 1) self-experienced victimization, 2) victimization of acquaintances, such as family and friends, and 3) having heard of stories in the media about online banking fraud victimization. Based on a secondary analysis of data from 1200 Dutch users of online banking, collected through an online survey, we conclude that participants perceive their risk of online banking fraud to be small. In general, participants have little experience with victimization, both themselves (2.3%) and in social settings (29.6%). Three quarters of the respondents (75.6%) are aware of victimization of online banking fraud by means of media coverage. Direct and indirect victimization, however, have almost no influence on risk perception regarding online banking fraud. Risk perception is mainly determined by perceived vulnerability, that is, the estimated probability of becoming a victim of online banking fraud. Furthermore, perceived severity or impact of online banking fraud and the degree of trust in online banking contribute to some extent to risk perception. In total, 64.0% of variance in risk perception was explained by the predictors perceived vulnerability, perceived severity, locus of control, trust in online banking, (in)direct experiences with victimization (self, acquaintances and media) and demographic variables (gender, age, educational level and work status). The results of this study may help to improve communication about risks regarding online banking.

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).

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.

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 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.
