What happened
Brazilian electricity distributor Light S.A. reported a cyber incident while security researchers linked the intrusion to Sodinokibi/REvil ransomware and a multimillion-dollar extortion demand. Public evidence did not establish an outage, compromise of operational technology or effect on electricity delivery. The record is marked reported because the ransomware-family attribution and claimed data access were not fully confirmed in a detailed company disclosure.
When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
