Een exploratieve studie naar de ambiguïteit van betrouwbaarheid van cocaïnedealers op Telegram Messenger

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden drug dealing, trust, signaling theory, social media, netnography
Auteurs Robby Roks en Joëlle Hendriksen
SamenvattingAuteursinformatie

    In order to advance our understanding of digital drug markets on social media, this article examines the trustworthiness of cocaine dealers on Telegram Messenger. Based on an exploratory netnography, we illustrate that digital dealers on Telegram Messenger use a number of sales tactics to attract potential customers, emphasizing the quality of the goods and service and (competitive) pricing strategies. These sales tactics include various signals that seem intended to appear as trustworthy as possible to potential customers. Seen from the perspective of signaling theory, our study highlights the ambiguity of these signals that, depending on the online observer, could both signal trustworthiness and untrustworthiness.

Een kijkje achter de schermen: een kwalitatieve studie over het ontstaan van cybercriminele carrières

Tijdschrift Tijdschrift voor Criminologie, Aflevering 1 2021
Trefwoorden cybercrime, cyber offenders, criminal careers, online disinhibition, pathways
Auteurs Sifra Matthijsse, Wytske van der Wagen, Elina van ’t Zand e.a.
SamenvattingAuteursinformatie

    This qualitative study examines how criminal careers in cybercrime start and can be explained. Based on offender and expert interviews, the authors conclude that traditional factors linked with the initiation, such as a maturity gap (for juvenile offenders) and opportunism (for adult offenders), in combination with different types of (online) disinhibition – social, technical, situational and psychological – can explain the start of a criminal career. Features of the digital context appear to play a major role in the development of a criminal career and this requires more online supervision and education about – among other things – legal alternatives and the risks and boundaries of the online environment.

Online jeugdcriminaliteit en ‘verkeerde vrienden’: wanneer is de samenhang het sterkst?

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2-3 2020
Trefwoorden cyber delinquency, cyber offenders, peer deviance, social network
Auteurs Yaloe van der Toolen MSc, Dr. Marleen Weulen Kranenbarg en Prof. dr. Frank Weerman
SamenvattingAuteursinformatie

    This article investigates whether cyber delinquent behaviour of school friends, other offline friends and online contacts is related to cyber delinquent behaviour of individuals, and whether this relation differs for cyber dependent, cyber enabled and traditional crime. We used both direct and indirect measures of cyber delinquency of friends. We employed data from the first wave of a large-scale study on the causes of online delinquency among Dutch juveniles (n=889; mean age=16.8 years). The results suggest that both direct and indirect measures of levels of friend delinquency were related to levels of individual cyber offending. However, indirect measures had a stronger association with individual online delinquency than direct measures. This suggests that respondents make incorrect estimates of their friends’ levels of online delinquency. Moreover, no differences were found in the strength of the relation between individual online offending and indirect measures of online offending of school friends, offline friends and online friends. This suggests that friends of different types all play an important role in individual online offending.

Het succes van social engineering

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1-2 2018
Trefwoorden Awareness, E-mail phishing, Social Engineering, Telefoonfraude
Auteurs Jan-Willem Bullée, Lorena Montoya, Marianne Junger e.a.
SamenvattingAuteursinformatie

    Social engineering is the usage of social manipulation and psychological tricks to make the targets assist offenders in their attack. This paper aimed to discuss the success of social engineering attacks and interventions in an organisational setting. Three kinds of social engineering experiments were discussed, each using a different modality (i.e. face-to-face (f2f), email and telephone). In each experiment, the targets (i.e. participants) were persuaded to perform actions that contribute to their victimisation.
    A portion of the participants in both the f2f and telephone experiment received an intervention to reduce victimisation. The conclusion is that awareness raising about dangers, characteristics and countermeasures related to social engineering proved to have a significant positive effect on protecting the target. The results of these experiments allow practitioners to focus awareness campaigns to maximise their effectiveness.

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.

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.

Georganiseerde misdaad in de 21ste eeuw

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2016
Trefwoorden organized crime
Auteurs Prof. dr. Toine Spapens, Prof. dr. Emile Kolthoff en Prof. dr. Wouter Stol
SamenvattingAuteursinformatie

    In the past decades, organised crime internationalised rapidly as a result of increasing mobility and ‘open’ borders. At the same time developments in information and communication technology have led to modernisation of existing types of crime and the introduction of novel ones. Finally, criminals have benefited from increasingly diversified migration streams. In the Netherlands and Belgium, organised crime appeared on the agenda in the 1990s. For a long time emphasis was on ‘trade crimes’ i.e. trafficking in drugs and humans, as well as human smuggling, followed by the production of synthetic drugs and cannabis. More recently the Low Countries are confronted by more visible manifestations of organised crime, for example rapid growth of outlaw motorcycle gangs. Criminals also try to utilise their capital to invest in businesses and real estate and to influence local politics.

De bestudering van criminaliteit op macroniveau: een inleiding

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2015
Trefwoorden macro criminology, theory, crime drop, punitive turn, micro-macro problem
Auteurs Dr. Frank Weerman, Dr. André van der Laan, Prof. Ineke Haen Marshall e.a.
SamenvattingAuteursinformatie

    In this introductory article we introduce the subject of our thematic issue on ‘macro criminology’, and illustrate it with a short historical overview and examples of ‘typical macro criminological’ research. Successively we address the recent decrease in crime in many Western countries (the ‘crime drop’), the increased tendency to punish more severely in the last decennia (the ‘punitive turn’), and historical developments in homicide (‘history of violence’). After that we address an important theoretical and philosophical problem with regard to macro criminology: the balance between micro and macro factors in explaining macro phenomena. Finally, the contributions of this thematic issue are introduced.

    The explosive growth of the Internet has led to countless new possibilities, and it opened the way for societal progress and an extensive globalization and digitization. However, the original ambition of the Internet as a free, open and neutral medium has also led to new possibilities in the field of crime. The current paper illustrates how governments dealt with the development of the Internet and it gives an explanation for why and how unintended side effects have manifested in society. Using the phenomenon of digital child abuse, this paper offers recommendations for an effective government response and for an effective detection of and fight against cybercrime.

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.

Virtuele ontmoetingsruimtes voor cybercriminelen

Tijdschrift Tijdschrift voor Criminologie, Aflevering 4 2012
Trefwoorden offender convergence settings, cyber crime, phishing, carding
Auteurs Dr. Melvin Soudijn en Eileen Monsma MSc
SamenvattingAuteursinformatie

    Felson introduced the concept of offender convergence settings in his articles on situational crime prevention. He refers to physical locations where criminals get together to relax, share information, fence stolen goods, plot new crimes, etc. Such places come in the form of restaurants and cafes that are in the hands of the ‘underworld’, but may equally well consist of deserted schoolyards where unruly adolescents gather. According to Felson, such settings facilitate the committing of crimes and enable the creation of structure and continuity in criminal networks.
    In this article the authors argue that virtual meeting places also exist that can be labeled as offender convergence settings. To demonstrate this, a case study regarding a so-called ‘carding’ forum is used. Carding is a term from the world of cybercrime and refers to the set of techniques by which personal financial information is acquired, traded and abused by criminals. Through a qualitative and a quantitative analysis of the carding forum, the possibilities for cyber criminals to come into contact with each other, co-offending, and the durability of the criminal network is analyzed.

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.
