Le capital virtuel : entre compétition, survie et réputation

Les avancées technologiques liées à l’internet ont permis une démocratisation des outils de communication et une transformation des relations interpersonnelles. L’impact de ces changements s’est ressenti autant dans la sphère légitime que dans les marchés criminels. Ces derniers ont migré, au cours des dernières années, vers des plateformes en ligne qui leur permettent de mieux gérer les risques associés avec leurs activités illégales. Cette thèse s’intéresse à l’impact de l’internet sur la criminalité et sur l’adaptation des criminels à cet environnement virtuel. Ces derniers forment maintenant des communautés en ligne et gardent le contact entre eux à l’aide de salles de clavardage et de forums de discussions. Nous nous intéresserons dans cette thèse à trois formes particulières de crime soit la fraude de propriété intellectuelle (la scène des warez), le piratage d’ordinateurs (les botnets) ainsi que la fraude de données personnelles et financières (le carding). Chacune de ces formes de crime sera analysée à l’aide d’un article publié ou présentement en évaluation. L’article sur la scène des warez décrit l'organisation sociale ainsi que la distribution de la reconnaissance dans la communauté des pirates informatiques. Les systèmes de délinquance (Sutherland, 1947) et l’individualisme réseauté (Boase & Wellman, 2006) sont utilisés pour théoriser l'organisation sociale et la distribution de la reconnaissance dans la scène warez. L’article sur les botnets tente de comprendre la distribution de la réputation dans une communauté de criminels. En utilisant les données d’un forum de discussion où des botmasters louent et achètent des biens et services illégaux, cette recherche modélise les facteurs qui permettent d’augmenter le niveau de réputation de certains acteurs. Finalement l’article sur le carding mesure le lien entre la réputation telle que développée par Glückler & Armbrüster (2003) et la performance criminelle. Notre thèse démontre que l’internet a eu un effet transformateur sur la criminalité à six niveaux : 1) l’augmentation de la facilité à trouver des co-criminels; 2) l’augmentation de la compétition entre les criminels; 3) l’augmentation du nombre de victimes; 4) la diminution des risques d’arrestation; 5) l’augmentation du taux de réussite des criminels et; 6) les changements dans l’équilibre entre criminels, victimes et protecteurs. Elle nous permet également de démontrer l’importance de la réputation, le capital virtuel, dans les marchés criminels en ligne.Technological advances related to the Internet have led to a democratization of the tools of communication and transformation of interpersonal relationships. The impact of these changes is felt both in the legitimate sphere as well as in criminal markets. These markets have migrated in recent years to online platforms that allow them to better manage the risks associated with their illegal activities. This thesis focuses on the impact of the Internet on crime and criminal adaptation in this virtual environment. These individuals now form online communities and keep in touch with each other using chat rooms and forums. We focus in this thesis on three specific forms of crime: intellectual property fraud (the warez scene), the hacking of computers (botnets) and fraud of personal and financial data (carding). Each of these forms of crime will be analyzed in an article that has either been published or is currently under review. The article on the warez scene describes the social organization and the distribution of recognition in the hacker community. Crime behavior system (Sutherland, 1947) and networked individualism (Boase & Wellman, 2006) are used to theorize social organization and distribution of recognition in the warez scene. The article on botnets aims to understand the distribution of reputation in this community for offenders. Using data from a forum where botmasters rent and buy illegal goods and services, this research models the factors that increase the level of reputation of some actors. Finally the article on carding measures the link between reputation as developed by Glückler & Armbruster (2003) and criminal performance. Our thesis demonstrates that the Internet has had a transformative effect on crime at six levels: 1) increase of the ease of finding co-offenders; 2) increased competition between offenders; 3) increase in the number of victims; 4) decrease in the risk of arrest; 5) increasing the success rate of criminals and; 6) changes in the balance between offenders, victims and protecteurs. It also allows us to demonstrate the importance of reputation, the virtual capital, on online market criminals

Modeling Human Group Behavior In Virtual Worlds

Virtual worlds and massively-multiplayer online games are rich sources of information about large-scale teams and groups, offering the tantalizing possibility of harvesting data about group formation, social networks, and network evolution. They provide new outlets for human social interaction that differ from both face-to-face interactions and non-physically-embodied social networking tools such as Facebook and Twitter. We aim to study group dynamics in these virtual worlds by collecting and analyzing public conversational patterns of users grouped in close physical proximity. To do this, we created a set of tools for monitoring, partitioning, and analyzing unstructured conversations between changing groups of participants in Second Life, a massively multi-player online user-constructed environment that allows users to construct and inhabit their own 3D world. Although there are some cues in the dialog, determining social interactions from unstructured chat data alone is a difficult problem, since these environments lack many of the cues that facilitate natural language processing in other conversational settings and different types of social media. Public chat data often features players who speak simultaneously, use jargon and emoticons, and only erratically adhere to conversational norms. Humans are adept social animals capable of identifying friendship groups from a combination of linguistic cues and social network patterns. But what is more important, the content of what people say or their history of social interactions? Moreover, is it possible to identify whether iii people are part of a group with changing membership merely from general network properties, such as measures of centrality and latent communities? These are the questions that we aim to answer in this thesis. The contributions of this thesis include: 1) a link prediction algorithm for identifying friendship relationships from unstructured chat data 2) a method for identifying social groups based on the results of community detection and topic analysis. The output of these two algorithms (links and group membership) are useful for studying a variety of research questions about human behavior in virtual worlds. To demonstrate this we have performed a longitudinal analysis of human groups in different regions of the Second Life virtual world. We believe that studies performed with our tools in virtual worlds will be a useful stepping stone toward creating a rich computational model of human group dynamics

La réussite criminelle des participants à la fraude financière en ligne

Le carding est un phénomène cybercriminel de par lequel des cyberdélinquants (appelés carders) vont compromettre et utiliser frauduleusement des données financières et bancaires. De nombreuses entités privées ou publiques ont mis en évidence l'importance des pertes monétaires occasionnées par ce nouveau type de criminalité. D'un point de vu criminologique, peu de recherches académiques se sont penchées sur l'ampleur de ce phénomène et plus particulièrement sur la réussite criminelle des carders. Pour combler ce manque de connaissances, ce projet de recherche a pour objectif de comprendre la réussite criminelle des carders en observant l'impact de leurs caractéristiques personnelles et sociales sur leurs revenus criminels. Les différentes variables mobilisées relatent entre autres les activités marchandes ou encore les caractéristiques sociodémographiques des carders interrogés. Pour ce faire, un sondage en ligné, hébergé sur Tor, a été mené. Au total, 49 sondages complets ont été collectés pour être analysés. En s'attelant à décrire les caractéristiques personnelles et sociales des carders, ce travail a été en mesure de mettre à jour les connaissances préalablement acquises sur les carders et de répondre à des manques de consensus sur certains pans des activités de ces cyberdélinquants. L'ensemble des résultats révèlent que peu de carders affichent une réussite criminelle élevée et qu'une minorité d'entre eux gagnent de forts revenus. La réussite crimnelle des carders s'explique par le fait de disposer de compétences spécialisées, de bénéficier d'une bonne expérience, d'utiliser des forums de discussion en ligne ou encore d'occuper des rôles centraux sur les lieux de convergence virtuels. Outre le fait d'apporter des réponses quant à ces prédicteurs sur la réussite criminelle des carders, ce projet de recherche permet de constater les apports et les faiblesses de l'utilisation d'un sondage pour collecter des données dans une écosystème cybercriminel.Carding is a criminal phenomenon which consists of compromising financial data in order to do fraudulent transactions. Several private and public parties highlighted the size of the loss caused by this new form of criminality. From the criminological angle, little research is available in the size and scope of the phenomenon, particularly on the criminal achievement of this kind of online offenders (called carders). To fill this gap, this research project is aimed at understand the criminal achievement of carders by observing the impact of their personal and social characteristics on their criminal income. Theses variables relate among others to their market activities or their sociodemographic. To do so, an online survey, hosted on Tor, was conducted. A total of 49 completed surveys were collected to do our analysis. By describing these personal and social characteristics, this work has been able to update our knowledge about carders and to address gaps about certain part of what we known about carding. Overall, the results shown that few carders can claim a good criminal achievement and that a minority of them can earn large amounts of money. Experience, speciliazed skills, the use of online forums or play the role of broker explained the criminal achievement among carders.Apart from the fact that our study brings some answers about those predictors, this project highlights the strengths and weaknesses of using an online survey to collect data from a criminal ecosystem

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

A social network analysis of Irish language use in social media

Statistics show that the world wide web is dominated by a few widely spoken languages. However, in quieter corners of the web, clusters of minority language speakers can be found interacting and sharing content. This study is the first to compare three such clusters of Irish language social media users. Social network analysis of the most active public sites of interaction through Irish – the Irish language blogosphere, the Irish language Twittersphere and a popular Irish language Facebook group – reveals unique networks of individuals communicating through Irish in unique and innovative ways. Firstly, it describes the members and their activity, and the size and structure of the networks they share. Then through focused discourse analysis of the core prolific users in each network it describes how the language has been adapted to computer-mediated communication. This study found that the largest networks of Irish speakers comprised between 150-300 regular participants each. Most members were adults, male, and lived in towns and cities outside of the language’s traditional heartland. Moreover, each group shared one common trait: though scattered geographically, through regular online interaction between core members they behave like communities. They were found to have shared histories, norms and customs, and self-awareness that their groups were unique. Furthermore, core users had adapted the language in new and innovative ways through their online discourse. This study is the first comprehensive audit of who is using the Irish language socially on the web, where they are forming networks online, and how they are adapting the language to online discourse. It makes a unique contribution in re-imagining what constitutes an Irish language community in the context of the Network Society. In the process, it contributes to the growing body of sociolinguistic research into globalisation and local identity on the web

Conceptualising Social Space in Cyberspace: A Study of the Interactions in Online Discussion forums

The study introduces an alternative analytic framework for the investigation of online discussion forums. It focuses on the social dynamics occurring in online discussion threads situated within a tertiary e-learning context, and advocated by social learning theories. Online discussion forums are perceived as conducive environments for the evolvement and support of collaborative and socio- constructivist learning. However, the literature reviewed, revealed a growing need for finding empiric frameworks for ascertaining the materialisation of these perceptions. Attempting to address the identified need, the study adopts ethnomethodological notions, complemented by Structural Analysis approach, to produce an alternative analytic frame called the Event Centre (EC) approach for the study of online discussion forums. The theoretical framework chosen in this study enables the investigation of online discussion forums as systems of relations rather than aggregations of individuals. The EC approach enables the visual representation of networks of people interacting with each other and at the same time presenting the content discussed in each interaction. Applying the EC approach to a set of 131online discussion threads, enabled the discovery of social dynamics occurring within the discussion threads. Preliminary investigations of these visually represented dynamics revealed two overarching patterns. One depicting uni directional interactions in which all participants referred to a single message and a second one depicting sequences of interactions organised in chain like patterns. The study suggests that these overarching patterns may imply different perceptions of knowledge as enacted by the participants, and hence possibly reveal different perceptions of teaching and learning through which it may be possible to detect collaborative and social constructivist processes. The study suggests that the visual patterns introduced should be perceived as abstractions of particular events, implying their generalisability and hence possible application to different data sets

Study on open science: The general state of the play in Open Science principles and practices at European life sciences institutes

Nowadays, open science is a hot topic on all levels and also is one of the priorities of the European Research Area. Components that are commonly associated with open science are open access, open data, open methodology, open source, open peer review, open science policies and citizen science. Open science may a great potential to connect and influence the practices of researchers, funding institutions and the public. In this paper, we evaluate the level of openness based on public surveys at four European life sciences institute
