MIT HJERTE Listed by nova Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
MIT HJERTE was listed by the nova ransomware group on June 20, 2026, after internal files were exfiltrated in a ransomware attack. Individuals connected to the organisation should check whether their information was exposed and take steps to protect themselves.
On June 20, 2026, the ransomware group nova listed MIT HJERTE on its leak site. The listing states that internal files were exfiltrated during a ransomware attack against the organization, which operates the patient-focused platforms mit-hjerte.de and mit-hjerte.dk. The number of people affected has not been disclosed.
What happened
The incident centers on a ransomware operation in which files were removed from MIT HJERTE systems. Nova’s listing asserts that the data were taken and offers to supply a directory listing along with sample files. The group states it will decrypt one file as a demonstration if the organization contacts its support channel. No further details on the timing of the intrusion, the volume of data, or the encryption status of remaining systems have been made public.
Inside nova
Nova is a ransomware group that publishes victim names on a dedicated leak site when negotiations fail. Its standard practice includes exfiltrating data before encryption and then releasing samples or directory trees to demonstrate possession. The group’s listing of MIT HJERTE follows this pattern; the claim that files were removed remains unverified by independent sources at this time.
MIT HJERTE and its sector
MIT HJERTE provides a digital service that delivers individualized information to patients diagnosed with heart disease. The platforms are used in Denmark and Germany. Organizations in this sector routinely process clinical correspondence, medication details, appointment records, and other health-related communications addressed to named individuals.
What was likely exposed
The only data type named in the listing is “internal files.” The precise categories of information contained in those files have not been disclosed. Healthcare platforms of this kind commonly store patient identifiers, treatment histories, and contact details, yet the exact contents removed in this case remain unconfirmed.
The real-world impact
Exposure of internal files from a patient-communication service could affect the privacy of individuals receiving cardiac care. Potential consequences include unauthorized access to personal health information and possible follow-on fraud or targeted scams. For the organization, the incident adds operational costs for investigation, notification, and system restoration, though the scale of those costs is not yet known.
What to do if you're exposed
Individuals who receive services from MIT HJERTE should monitor their email and postal addresses for unusual activity and review any financial or insurance statements for discrepancies. Changing passwords on associated accounts and enabling multi-factor authentication where available are immediate steps. Readers can run a free exposure scan of their email address to check whether their information appears in known breach data sets.

Publicly posted by nova — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
