Operator dossier

Sabbath is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 17 public victims claimed by this operator between November 22, 2021 and February 28, 2022. Sabbath is a relatively obscure ransomware group that emerged in November 2021, operating with apparent financial motivations and targeting a limited number of victims across telecommunications and education sectors. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, with no confirmed details about their operational structure or whether they operate as an independent entity or part of a broader ransomware-as-a-service ecosystem. With only 17 known victims primarily concentrated in the United States and United Kingdom, Sabbath appears to focus on telecommunications and education sectors, though specific details about their initial access vectors, encryption methods, or use of double extortion tactics have not been extensively documented by major security firms or government agencies. The group has not been associated with any widely publicized high-profile attacks or significant law enforcement actions, suggesting a lower operational profile compared to major ransomware families. Current intelligence indicates limited visibility into Sabbath's ongoing activities, with insufficient public documentation to definitively assess whether the group remains active, has ceased operations, or has undergone rebranding.

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.
