Rancoz is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 6 public victims claimed by this operator between May 5, 2023 and September 3, 2023. Rancoz is a relatively obscure ransomware group that emerged in May 2023, operating with apparent financial motivations and maintaining a low profile compared to major ransomware families. The group's origin and affiliations remain largely undetermined due to limited public documentation from major cybersecurity agencies and research organizations, with no confirmed information regarding their country of origin or whether they operate as a Ransomware-as-a-Service model. Based on available targeting data, Rancoz appears to focus primarily on manufacturing sector organizations within the United States, though their specific attack methodology, initial access vectors, and technical capabilities have not been extensively documented in public threat intelligence reports from established sources such as CISA, FBI, or major cybersecurity firms. With only six known victims documented since their emergence, the group has not conducted any widely-publicized major campaigns or attracted significant law enforcement attention that has been made public. Current intelligence suggests the group remains active as of recent observations, though their limited victim count and low public profile indicate they operate as a relatively minor threat actor within the broader ransomware ecosystem.
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.
