Challenges and Opportunities in Digital and Multimedia Evidence
Netherlands Forensic Institute


Within Digital Evidence and Multimedia sections in forensic institutes there is a wide range of research and casework that is available. Often research for the casework has to be implemented, and validation will be required at the same time, unless it is equipment from other cases in a database. In this presentation an general overview will be given of the fields within digital evidence, such as embedded systems, examinations of phones, media analysis, data analysis, image processing and integrity of the evidence.

Interpretation of digital evidence and multimedia and conclusions that are drawn are discussed also in relation to the report of the National Academy of Sciences "Strengthening Forensic Science in the United States, a path forward". Possible solutions will be discussed such as having double blind cases, collecting databases for statistical analysis, open source software for validation, concluding by Bayes rules and how to communicate these findings to the court.

Benoît Gagnon

Who are they? Understanding computer hackers
Chaire du Canada en Sécurité, Identité et Technologie

Abstract: In February 2008, the Sûreté du Quebec uncovered a network of computer hackers from Quebec that were herding botnets for criminal purposes. Called Operation "Basique", this investigation went on for several months and collected an important quantity of information on their modi operandi. What can we learn from the data obtained in this investigation? This presentation will expose the results of our research exploiting this data. We will be able to see how the bot herders operate, how they conceive the World and how personal relationships influence their actions

Bio: Benoît Gagnon is a Ph.D. candidate in Criminology at the University of Montreal. He works as a research fellow at the Chaire du Canada en Sécurité, Identité et Technologie and at the Terrorism and Counter-terrorism Research Group on areas such as cybercrime, terrorism and security. M. Gagnon is a member of the Commission de l'Éthique de la Science et de la Technologie du Québec, the Computer Security Institute, the Canadian Association for Security and Intelligence Studies, the International Association for Counterterrorism and Security Professionals, and the American Society for Industrial Security (ASIS).
