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.

De twitterende wijkagent en het veiligheidsgevoel van de burger

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2016
Trefwoorden Twitter, police, safety perceptions, communication, social media
Auteurs Imke Smulders, Wilbert Spooren en Emile Kolthoff
SamenvattingAuteursinformatie

    This article reports on a conceptual model that provides insight into the relationship between Twitter use by community policing officers and citizens’ safety perceptions. The model has been tested using data from a relatively large-scale survey study and these results are supporting the model. Furthermore, a small impact of Twitter use has been found on feelings of safety and judgments about the police. To confirm these findings, further research on a larger scale is necessary. To find out more about the exact positive and negative effects of Twitter use by community policing officers, a more experimental design is required.

Positieve veiligheid. Een theoretische analyse van een omstreden begrip

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2015
Trefwoorden Positieve veiligheid, geschiedenis, begripsanalyse, kritiek, ethiek
Auteurs Gerben Bakker
SamenvattingAuteursinformatie

    The concept of positive security appears more and more often in academic and public discussions. It presents a normative agenda for a non-repressive approach of security. In the article, it is claimed that the concept and its implications lack fundamental clarity. First of all, it is illustrated that the meaning of positive security primarily develops on the renouncement of negative security. Second, a historical comparison between the discipline of international relations and criminology discloses that different meanings have been assigned to positive security that seem at times at odds with each other. These frictions substantiate the view that it is problematic to accept positive security as an unequivocal recipe for change. Finally, the consequences of the disseminated structure of meaning are discussed in relation to the ambition of reform that positive security represents. For example, advocates of positive security do not seem eager to commit themselves to very clear normative views. This makes it difficult to really pin down what the suggested changes underlying positive security, are truly implying. Moreover, positive security invites us to extend the horizon of security politics to include various kinds of positive needs and values. But doesn’t this take us back to the initial criticism that the reach of the security concept has extended too much, covering virtually every aspect of life?

De ene graffiti is de andere niet

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2012
Trefwoorden graffiti, perceptie, overlast, visuele methoden, verwijderingsbeleid
Auteurs Gabry Vanderveen en Funda Jelsma
SamenvattingAuteursinformatie

    Graffiti has been linked in empirical studies to disorder, fear of crime, avoidance behavior, vandalism and delinquency. In most of those studies, graffiti is treated as an abstract and uniform concept: no distinctions are made between one graffiti or another. Policies based on this assumption hold a zero tolerance approach, meaning all graffiti is deemed undesirable and is or should be removed. This has been criticized by several (theoretical) studies. On the other hand however, ethnographic studies present graffiti as a multifaceted phenomenon, serving as a means of communication, resistance and protest or as an art form. The current study investigates the assumption that graffiti is perceived as a homogeneous and undesirable environmental feature. This article examines whether graffiti is actually perceived uniformly by Dutch citizens, and if not how people distinguish between different graffiti; which types of graffiti are perceived as disorder and whether different types of people exist based on their attitudes towards graffiti. An extensive questionnaire was designed, based on a thorough analysis of the literature and empirical pilot studies. A nationally representative sample responded to general questions with respect to graffiti and judged eighteen specific examples of graffiti on a reliable scale that measured perceived disorder. Results indicate that people vary enormously in their ideas and attitudes. Also, not every graffiti is the same, meaning graffiti is not a homogeneous, uniform phenomenon. Both type of graffiti and the location on which the graffiti is situated relate to the degree of perceived disorder. For example, tags, small scribbles, were considered a public nuisance more than pieces, large colorful images. Also, graffiti on a house or car is perceived much more as disorder than graffiti in a skatepark. The diversity in views necessitates a normative

Agenten volgen via Twitter bevordert positieve beeldvorming, stimuleert de meldingsbereidheid en verandert de veiligheidsbeleving

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2012
Trefwoorden Twitter, community policing, transparency, perception, willingness to report
Auteurs Leon Veltman, Marianne Junger en Roy Johannink
SamenvattingAuteursinformatie

    Since November 2009, the regional police of Groningen facilitated their community officers with Twitter. According to the principles of community policing, they are enabled to shorten the distance between the police and citizens by giving them a direct connection. Such a connection should stimulate interaction, while at the same time it should make people feel more safe. In addition, Twitter also creates possibilities for the police to be transparent. Sharing of information should alter citizens’ perception towards the police.
    A comparison has been made, by using an online questionnaire, between followers and two kinds of non-followers. The effects of following twittering community officers have been demonstrated by using statistical analyses, taking into account relevant control variables. On the basis of these analyses it has been demonstrated that following a twittering community officer did not positively or negatively alter the perception of safety of their followers. However, an enhanced information position has made followers much more aware of local disorder and crime. Thanks to shared information about police actions to sustain and improve local safety and livability, followers’ perception of safety has not been altered negatively.
    Followers’ perception towards the police organization has been positively altered, thanks to the twittering community officers. Especially the sharing of information and involving citizens into local policing helps the police to alter the perception of citizens towards their organization. In addition, it has been shown that followers’ willingness to report has been improved. Thanks to the ease of use of Twitter and the shortened distance between the police and citizens, followers do frequently contact the police or a community officer to share some information, or to report some crime or disorder. However, it has been shown that Twitter should just be presented as complementary to existing ways to contact the police.

Identificatie van Nederlandse jongeren die risico lopen op internet

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2012
Trefwoorden Youth, internet use, online victimization, risk profile, risk factors
Auteurs Joyce Kerstens en Johan van Wilsem
SamenvattingAuteursinformatie

    This article describes the findings of a national representative survey on online victimization. The survey was conducted in the Netherlands in 2011 amongst youth aged 10 to 18. Purpose of this research is to identify various risk factors related to cyber bullying, online sexual activities and online financial crime (e.g. e-fraude and commercial deceit). More than 9 percent of the youths had negative experiences with cyber bullying, about 5 percent with e-fraude and over 11 percent with commercial deceit. Also unwanted online sexual solicitations (6%) and unwanted exposure to sexually explicit internet material (12%) occurred with some regularity.
    This research complements earlier research on youth victimization in two important respects. First, we paid explicit attention to determine whether the youngster experienced the online incident as negative, neutral or positive. Our strategy to address negative experiences ensures the identification of actual victims. Secondly, we made it possible to identify and compare risk factors on various types of online crime. Girls are more likely to be cyber bullied, to receive unwanted sexual solicitations and to be unwantedly exposed to online pornography, whilst boys are more at risk to be commercially deceived or scammed.
    Internet use and behaviour are significant risk factors to comprehend online victimization. Above average use of instant messaging and clicking on (advertising) hyperlinks without restraint, are important predictors for online victimization. Finally, online disinhibition - a loosening of social restrictions during interactions with others on the Internet - and low self-control, turn out to be significant risk factors.
    It is difficult to accept certain risks, especially when youth are involved. However, children have to learn themselves to assess risks, to deal with them and to learn from them. It is important youths built up resilience to adequately react on negative online incidents and to reduce online vulnerability.

Slachtofferschap van online oplichting nader onderzocht

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.
