The European Commission has called for improved capacity of the EU and its Member States to attribute cyber-attacks. In its joint communication to the European Parliament, the European Council and the Council, "Increasing resilience and bolstering capabilities to address hybrid threats", the Commission emphasised the importance of attribution to deterring potential aggressors and holding the culprits accountable. Member States were encouraged to continue their work on attribution of cyber-attacks and the practical use of the cyber diplomacy toolbox to step up the political response to cyberattacks. The Commision also urged the European Parliament and the Council to swiftly agree on the proposed legislation on gathering electronic evidence, as it would significantly enhance the ability of law enforcement to investigate and prosecute cybercrime.
