Exploring the use of encrypted evidence in serious and organised crime cases

Prosecutors and law enforcement representatives from the Western Balkan and the Eastern Partnership countries met this week in The Hague for a workshop focused on the use of encrypted communication evidence in organised crime cases. The activity was organised by Eurojust’s Western Balkans Criminal Justice (WBCJ) project and CEPOL’s WB PaCT and TOPCOP projects, in partnership with Europol.
The workshop addressed one of the most pressing challenges in today’s fight against serious and organised crime: how to effectively use evidence derived from encrypted communications in criminal investigations and court proceedings. As highlighted by the EU Serious and Organised Crime Threat Assessment (EU-SOCTA), criminal networks increasingly rely on advanced technologies and secure communication tools to evade detection, creating new challenges for investigators, prosecutors and courts alike.
Against this background, the workshop provided a platform for practitioners to exchange experiences and examined recent developments across Europe and partner regions. Discussions focused on operational support for decryption, the use of decrypted communications in cross-border investigations, and recent court developments concerning the admissibility of evidence and challenges raised by the defence.
“The workshop provided valuable insight into how large-scale encrypted communication data can be analysed and turned into actionable intelligence, while also allowing us to share our experience on analytical work and the handling of such evidence in court,” said Rafayel Poghosyan, Armenian National EMPACT Coordinator.
Representatives from the EMPACT network also took part, underlining the workshop’s relevance to the EU’s co-ordinated response to serious and organised crime.
By bringing together key actors from different regions and professional backgrounds, the workshop contributed to a shared understanding of how to address increasingly complex criminal investigations involving encrypted communications. It also reinforced cooperation between operational and judicial authorities, helping partners respond more effectively to technology-driven crime threats.
