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.

De film Project X en de rellen in Haren (2012)

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1 2016
Trefwoorden Film, public imagination, public safety, Riots, Youth
Auteurs Heidi de Mare
SamenvattingAuteursinformatie

    On September 21th 2012, a sweet sixteen party in Haren (a Dutch village), announced on Facebook as PROJECT X Haren, turned into a riot in which youngsters clashed with the police. The blame was put on the film Project X (2012) that would have inspired adolescents to become aggressive and violent. However, like other adolescent comedies, this movie offers an insight in the adolescent state of mind, the role of humor and their lack of risk assessments. Much violence is (harmless) slapstick-like, boundaries are exceeded (sex, alcohol, drugs) and transgression is often directed against parents, teachers and the police. What is tested in the adolescent imagination is the public order. Film functions as a symbolic rite of passage, with carnivalesque inversions. Reacting in Haren on this adolescent state of mind with an administrative prohibition (‘there is no party’) confirmed the juvenile joke. Acting as if it is not a party but a huge disaster (by enlarging police forces) contributed to make the riot a reality that the youngsters themselves never imagined. The commission of inquiry recommends taking serious film and other forms of public imagination, because they contribute to our understanding of reality, especially concerning the perceptions of societal actors.

Uitbuiting uit zicht?

Getuigenverklaringen van gesmokkelde migranten nader bekeken aan de hand van indicatoren voor mensenhandel

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2012
Trefwoorden human trafficking, migrant smuggling, irregular migration, exploitation, illegal employment
Auteurs Joanne van der van der Leun en Anet van van Schijndel
SamenvattingAuteursinformatie

    Human trafficking means exploitation; human smuggling is associated with illegal labour and a connection with exploitation is absent. Where a victim of human trafficking can appeal for legal protection, a smuggled migrant (illegally residing or with vulnerable legal status) overall has little rights because of the formal absence of the aspects of exploitation and coercion in human smuggling. In this article, the empirical analysis based on file analysis demonstrates that in several files of cases framed as human smuggling indications are found for exploitation of migrants, although this has not been recognised as such. Theoretically the authors tie this to the trend of crimmigration. Measures designed to combat human trafficking and smuggling are often concentrated on (criminal) law enforcement and criminal punishment, to the detriment of a human rights-based approach. The tension between immigration policy and the combat against human trafficking deserves more attention.

Terroristische netwerken en intelligence: een sociale netwerkanalyse van de Hofstadgroep

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2009
Trefwoorden sociale netwerkanalyse, terrorisme, Hofstadgroep
Auteurs Dr. Renée C. van der Hulst
SamenvattingAuteursinformatie

    Radicalization and terrorism remain areas of special interest in terms of security policies. It’s common knowledge that most of the activities related to radicalization and terrorism heavily rely on the involvement of multiple actors. Therefore, an increased understanding of the underlying social structures is considered to offer important leads for the development of effective countermeasures (in particular when related to demographic, cultural, psychological and other social factors). Yet, the number of empirical network studies in this domain (at least those openly available) that incorporate arithmetic tools known as Social Network Analysis (SNA) remain extremely scarce. In this paper the author presents an exploratory Social Network Analysis of the Hofstad network based on publicly available data. Members of the Hofstad network, a radical Islamist network in the Netherlands, were active recruiters for the violent jihad, spreaded radical propaganda, some attended training camps in Pakistan, and the network was suspected of planning several terrorist attacks on strategic objects and prominent people in the Netherlands. One of the members, Mohammed B., was sentenced to life in prison for murdering the Dutch filmmaker Theo van Gogh in November 2004. Although the Hofstad network was considered by trial as a terrorist organization in the first instance in 2006, the judgment was reversed on appeal in 2008 when most members were acquitted. As is characteristic of home-grown networks, our analysis indicated that the Hofstad network (N=67) was relatively sparse and decentralized and evolved around a more cohesive core of key players (N=13). The key players were identified based on their central network position and a hierarchical clique analysis. Mohammed B., who had been considered a marginal player by the secret service, turns out to be the most central actor of the network. Although the analysis clearly suggests that quantifying network structures provides actionable intelligence, more research is needed to validate the results.
