16.05.2025 – As expected, DDoS attacks have been launched against various Swiss websites in connection with the Eurovision Song Contest (ESC). The DDoS attacks have so far not affected the Eurovision Song Contest’s operations. These attacks are aimed at attracting media attention and do not result in any data leakage.
As expected, before the final of the Eurovision Song Contest (ESC), denial-of-service attacks began targeting various organisations linked to the event. The aim of a DDoS attack is to overload websites and applications with targeted requests to such an extent that they are no longer or only partially accessible. The attacks are in line with our previous expectations and have so far had no impact on the ESC. No data leaks during such DDoS attack.
The NCSC expects such DDoS attacks to continue until the end of the Eurovision Song Contest. They are a popular means for attackers to draw attention to themselves. The NCSC has already warned the operators of critical infrastructures and organisations involved in the organisation of the Eurovision Song Contest about such attacks and called on them to take appropriate measures. The federal administration is continuously adapting security measures to current circumstances. The NCSC also liaises closely with national and international partners and with the operators of critical infrastructures.
Information for media representatives
With such attacks on the availability of websites and services, the perpetrators usually want to attract media attention in order to spread their ideology. The NCSC asks journalists to bear this in mind when writing their articles, so that the attackers receive as little attention as possible.
