Disclosure context

About nova

Based on the limited available data, Nova is a recently emerged ransomware operation first observed in April 2025 with an apparent financial motivation, having targeted approximately 95 victims in its brief operational period. The group's origin and potential affiliations remain undocumented by major security firms, though their targeting pattern suggests a broad opportunistic approach rather than geopolitically motivated attacks. Nova's attack methodology and specific technical capabilities have not been publicly detailed by established threat intelligence sources, though their victim distribution across the United States, France, Brazil, Singapore, and the Netherlands indicates either automated widespread targeting or access to diverse initial compromise vectors. The group has demonstrated a preference for targeting healthcare, technology, manufacturing, and education sectors, suggesting they may focus on organizations with critical operational dependencies that increase pressure for ransom payment. Given the group's recent emergence and limited public documentation by major security researchers, Nova's current operational status, organizational structure, and long-term threat trajectory remain largely uncharacterized in established threat intelligence reporting. The group has been linked to 170 public disclosures across our corpus. First observed on a leak site on April 28, 2025; most recent post June 20, 2026. The operation is currently active.

If your organisation is affected

A listing by nova means MIT HJERTE appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Report the incident to your national CERT, CFCS (Denmark), as required for your jurisdiction.
  • Monitor for the data appearing on nova's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
