Impact verdict
Medium impact. MEDIUM: Critical infrastructure cyber attack on a water utility serving 2 million customers is directly relevant to cyber insurance books, particularly those with coverage for operational technology (OT) disruption and business interruption. Liability exposure exists if public health is affected. Insufficient detail currently to confirm loss quantum or attack vector, but scale of affected population and EPA notification suggest potential for material claims. TRIA zone applicability possible if state-sponsored attribution is established.
