Vasileios Mavroeidis

Vasileios Mavroeidis is an Associate Professor in Digital Security at the Department of Informatics, University of Oslo (UiO). He specializes in security automation and orchestration (SOAR) and cyber threat intelligence (CTI) representation, reasoning, and sharing. He actively contributes to European cybersecurity initiatives, including Horizon Europe, Connecting Europe Facility, and the European Defense Fund, and serves as the primary representative of UiO at the OASIS standards development organization since 2017.

• Role: Associate Professor
• Department: Digital Security (SEC), University of Oslo
• Standardization Involvement: Chairman of OASIS Threat Actor Context (TAC), Leading Contributor to CACAO and OpenC2
• Projects: Concordia, CyberHunt, JCOP (Joint Cyber Security Operations Platform), Oslo Analytics, P4C (Partnership for Cybersecurity)

His research focuses on cyber threat intelligence (CTI), exploring its taxonomies, sharing standards (STIX, CACAO), and ontologies, with contributions to the European Union Agency for Cybersecurity (ENISA) Cybersecurity Playbooks task force. He analyzes quantum computing's impact on cryptography, develops automated threat detection systems using machine learning (e.g., recurrent neural networks for malware-generated domains), and investigates privacy issues under GDPR.

Recent publications highlight his work on LLMs for code stylometry, neurosymbolic AI for cyber defense, and knowledge management systems for CACAO playbooks. His articles span 2017–2025, emphasizing formal verification, biometric data protection, and incident response automation.

He collaborates with organizations like OASIS (Threat Actor Context, CACAO, OpenC2) and FIRST (Traffic Light Protocol), and participates in European research projects. His work includes standardization efforts in cybersecurity playbooks, MITRE ATT&CK representation, and quantum-resistant cryptography.
