Sabbath

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.
