Slachtofferschap van cybercrime in kaart gebracht

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.

Politieonderzoek in open bronnen op internet

Strafvorderlijke aspecten

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2012
Trefwoorden criminal investigation, surveillance, OSINT, investigation powers, legal basis
Auteurs Bert-Jaap Koops
SamenvattingAuteursinformatie

    Analysing large amounts of data goes to the heart of the challenges confronting intelligence and law enforcement professionals today. Increasingly, this involves Internet data that are ‘open source’ or ‘publicly available’. Projects such as the European FP7 VIRTUOSO aim at developing platforms for open-source intelligence by law enforcement and public security, which open up opportunities for large-scale, automated data gathering and analysis. However, the mere fact that data are publicly available does not imply an absence of restrictions to researching them. This paper investigates one area of legal constraints, namely Dutch criminal-procedure law in relation to open-source data gathering by the police. Which legal basis is there for this activity? And under what conditions can foreign open sources be investigated?
    After sketching the context of the VIRTUOSO project and legal constraints of open-source intelligence in general, this paper discusses provisions of the Dutch Police Act 1993 and the Code of Criminal Procedure to determine which is the correct legal basis for gathering data from openly accessible and semi-open sources. Next, cross-border gathering of data is discussed on the basis of article 32 of the Cybercrime Convention. The paper draws the conclusion that investigating open sources by the police will often go beyond what is allowed on the basis of the general task description of the police (art. 2 Police Act 1993); hence, an order from the Public Prosecutor for systematic observation or intelligence is required. Moreover, the tools used must meet the non-manipulability and auditing requirements of the Dutch Decree on Technical Devices in Criminal Procedure.

Downloaders van kinderporno

Een overzicht van de literatuur

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2010
Trefwoorden Kinderporno, Downloaden, Zedencriminaliteit, Literatuurstudie
Auteurs Anton van Wijk
SamenvattingAuteursinformatie

    Unlike the physical abusers of children, little is known about downloaders of child pornography. The key questions in this article are: who are the downloaders, what are their backgrounds, why and how they download child pornography, how they behave offline and online and what types of downloaders can be distinguished? A simple answer to these questions is currently impossible to give. There is more, preferably longitudinal, research needed on risk factors for downloading child pornography and the various types of downloaders. Combating the downloaders requires a lot of the police in terms of international cooperation and up to date knowledge and expertise. This also served the treatment practices, which is partly dependent on a properly conducted police investigation.

Slachtofferschap van online oplichting nader onderzocht

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.

Additioneel seksueel gedrag van kinderpornodownloaders

Onderzoek naar additioneel seksueel gedrag met kinderen in een groep van 38 kinderpornodownloaders met behulp van gecombineerde zelfrapportage en polygrafie (Sexual History Disclosure Polygraph Examinations)

SamenvattingAuteursinformatie

    This article presents a study on Post-Conviction Polygraphy in the Netherlands. Importantly, it exclusively focuses on cybercrime offenders. The study was designed to systematically address the different child sexual behaviours exhibited by 38 subjects who were in treatment for possessing child abuse images. The results gave indications that post-conviction polygraphy can provide additional data to inform the development of theory in this area and contribute to the treatment, supervision and more effective containment of offending behaviour, and the reduction of future victimization.
