Disclosure context

About N0n

N0n is a ransomware group first observed in September 2026 with an apparent financial motivation, having claimed at least 9 victims across a geographically diverse target set spanning Vietnam, the United States, Luxembourg, Brazil, and Argentina. Given the recency of their emergence and the limited volume of publicly documented activity, no verified attribution regarding country of origin, affiliation with known threat actors, or operational infrastructure has been established by CISA, the FBI, Mandiant, or other reputable security research organizations at this time. Their targeting pattern suggests an opportunistic rather than narrowly focused operational approach, with victims identified across the financial services, education, healthcare, government and defense, and general industry sectors, indicating a broad victim selection methodology rather than sector-specific specialization. No specific initial access vectors, malware tooling, encryption methods, or extortion tactics have been publicly attributed to this group in open-source intelligence reporting, and no major high-profile campaigns, record ransom demands, or law enforcement actions have been publicly documented against them. As of the time of this profile, N0n remains a nascent and poorly understood threat actor warranting continued monitoring given their cross-continental targeting scope and presence in sensitive sectors, though the low victim count and absence of corroborating technical reporting limit definitive characterization of their capabilities or long-term operational intent. The group has been linked to 92 public disclosures across our corpus. First observed on a leak site on September 18, 2026; most recent post October 12, 2026. The operation is currently active.

If your organisation is affected

A listing by N0n means Tsuneishi / Kambara Kisen (shipbuilding and ship management) 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, JPCERT/CC (Japan), as required for your jurisdiction.
Monitor for the data appearing on N0n'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.
