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 117 public disclosures across our corpus. First observed on a leak site on April 28, 2025; most recent post May 20, 2026. The operation is currently active.
