Disclosure context

About Nitrogen

**Nitrogen** is an emerging ransomware group that first appeared in September 2024, operating with apparent financial motivations through targeted extortion campaigns primarily focused on North American and European organizations. The group has claimed responsibility for attacks against 46 documented victims across multiple sectors, with manufacturing companies representing their most frequent targets. Limited public information suggests the group operates independently rather than as a Ransomware-as-a-Service model, though their specific country of origin and potential affiliations with other cybercriminal organizations remain undetermined by major security research firms. Their attack methodology appears to focus on opportunistic targeting across diverse industries including manufacturing, business services, technology, and hospitality sectors, with the United States serving as their primary area of operations followed by significant activity in Canada, Portugal, India, and France. Due to the group's recent emergence and relatively low profile compared to established ransomware families, detailed technical analysis of their encryption methods, data exfiltration practices, and initial access vectors has not been extensively documented by major threat intelligence providers such as CISA, FBI, or Mandiant. Given the group's recent formation in September 2024, no major high-profile campaigns or significant law enforcement actions have been publicly reported, with their victim portfolio consisting primarily of small to medium-sized enterprises rather than critical infrastructure or Fortune 500 companies. Nitrogen appears to remain active as of current reporting, though their limited operational history and relatively small victim count suggest they are still establishing their presence within the broader ransomware ecosystem. The group has been linked to 56 public disclosures across our corpus. First observed on a leak site on September 30, 2024; most recent post May 13, 2026. The operation is currently active.
