Sabrina Medeiros was invited as a speaker in the international event “Threats in the Network: Organized Crime, Terrorism and Violence”, held at Universidad Complutense de Madrid on March 23, 2026.
The event brought together scholars and experts from several European institutions, including Universidad Complutense de Madrid, Universidad Camilo José Cela, and UDIMA, fostering an interdisciplinary discussion on contemporary challenges in cybersecurity.
In her talk, “Digital Sovereignty and Cyber Power: Rethinking Security Beyond the Virtual”, Sabrina Medeiros examined cybercrime as a structured global economy, highlighting its transnational value chains, market dynamics, and implications for international governance.
The presentation emphasized three key dimensions:
• the increasing economic sophistication of cybercrime, including models such as ransomware-as-a-service
• the limitations of fragmented regulatory responses in addressing agile global illicit economies
• the need to strengthen multilateral governance frameworks, including greater inclusion of Global South perspectives
The event also featured contributions on pharmaceutical trafficking and illicit markets in the dark web, cyber fraud, and terrorism in cyberspace, offering a comprehensive overview of emerging threats.
The event was organized by Professors Concepción Anguita Olmedo, Carolina Sampó, and Carmen Jordá, to whom we extend our appreciation for the invitation and excellent academic coordination.
