nozelesn is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 1 public victims claimed by this operator between December 17, 2018. **Nozelesn** is an obscure ransomware group that first emerged in December 2018 with apparent financial motivations, though limited public documentation exists about their operations. The group's origin and affiliations remain largely unknown, with no confirmed country of origin or established links to other ransomware families documented by major security firms or law enforcement agencies. Their attack methodology and technical capabilities are not well-documented in public threat intelligence reports, with no detailed analysis available from CISA, FBI, or prominent security researchers regarding their initial access vectors, encryption methods, or whether they employ data exfiltration tactics. Based on available data, the group has targeted at least one victim in the United States government facilities sector, though no major high-profile campaigns or significant ransoms have been publicly reported by security researchers. The current operational status of nozelesn remains unclear due to the limited intelligence available about this group's activities beyond their initial emergence period.
How we know this. Operator profiles on Darkfield are built from continuous monitoring of every leak site the group is known to operate, cross-correlated with community-curated feeds (RansomLook, ransomware.live, RansomWatch, MISP-galaxy). Status flips from active to inactive when no new disclosure appears for 60 days. MITRE ATT&CK mappings shown in the interactive section below are sourced from CISA, vendor analysis, and the MITRE community catalog — we attribute each technique back to its source. Aliases reflect operator re-brands and affiliate splits.
