Unverified threat-actor claim — not a regulatory filing
Attribution, victim identity, and counts shown here derive from sabbath's public extortion-blog claims, aggregated by ransomware.live. They have not been validated by the victim or any regulator. Treat them as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.
According to ransomware.live, the group claims:
Sabbath (also known as 54BB47h, operated by UNC2190) is a ransomware group active from mid-2021 that emerged as a rebrand of the Arcane ransomware, targeting critical infrastructure in the US and Canada — particularly hospitals, schools, and natural resources — using double extortion, backup destruction, and affiliate recruitment on Russian-language dark web forums.
