Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Sinobi on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.
