On April 5th, the European Parliament, the European Commission and the EU Agency for cybersecurity (ENISA) in close cooperation with the EU Member States organised an exercise to test the EU’s response to and crisis plans for potential cybersecurity incidents affecting the EU elections. This report is divided into three (3) sections. In the first section, a summary of the national briefings is presented while in the second the results of the preparatory survey are presented together with some key conclusions. In the third section, the exercise scenario is presented together with the various incidents, injects and main takeaways from the players’ votes. Finally, in the Annexes we present anonymized responses to the injects and the satisfaction survey results.
