This website provides an overview of registered cyberattacks in Denmark in 2024. Denmark is located in Scandinavia, Europe. The chronological listing includes the date, the organization or company affected and the respective location. Our information is based on official notifications from companies as well as reports from newspapers and trade magazines. However, as not all incidents are made public, the actual number of successful cyberattacks is probably considerably higher.

Notes

  • The statistics are based on the known incidents listed here.
  • Since only some of the cases become known, the evaluations are not representative.
  • Industries where incidents are immediately visible due to public access (e.g. healthcare) are more represented than others.
  • An incident may be assigned to multiple countries or industries. Also, a country cannot always be assigned. So the totals shown on the charts may be different.
  • The graphics marked in this way may be reused according to the license Creative Commons Attribution 4.0 / CC BY 4.0, also for commercial purposes (Attribution: KonBriefing Research).
