On June 20, 2026, the Danish health platform mit-hjerte.de and mit-hjerte.dk appeared on the leak site of the nova Ransomware Group. The company, which provides personalised information to patients with heart disease, is claimed to have had internal files exfiltrated during a ransomware attack. Nova provided a tree of stolen data and sample files, offering to decrypt one file if the organisation contacts their support department.
Already exposed?
You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows
Public reporting indicates that nova exfiltrated internal files from the Mit Hjerte platform. The exact number of patients or records affected remains unknown. The leak site lists both the .de and .dk domains and shows a directory structure of the stolen material. As of the publication date, the group had not published the full dataset but was using the partial leak and decryption offer as leverage.
June 20, 2026 marks the date the incident was listed. The platform’s purpose is to deliver targeted medical information to individuals living with cardiac conditions, which means the compromised files could contain sensitive health-related records, contact details, and personal identifiers.
Why This Matters for You and Your Family
If you or a family member has used Mit Hjerte services, your personal health information may now sit in the hands of criminals. Health data is especially damaging when exposed because it can be used for identity theft, insurance discrimination, or targeted fraud. Even if you were not a direct patient, the breach highlights how everyday medical platforms can become entry points for broader data leaks that eventually reach you.
