Situation Report: Heightened Threat Environment – Potential Retaliation by Iranian Threat Actors Following U.S. Strikes on Iran (Updated March 26, 2026)

(TLP:AMBER+STRICT) The U.S.-Israeli conflict with Iran is now in its fourth week. U.S. and Israeli forces are continuing to conduct strikes across Iran, as Iranian forces persist in their retaliatory missile and drone attacks on regional countries, albeit at a reduced tempo. Despite media reports of potential negotiations between the warring parties, additional military personnel are currently enroute to the region, suggesting that the conflict could endure for at least a few more weeks. Since the last Iran update, WaterISAC has received additional reports concerning both ongoing cyber and physical security risks to critical infrastructure entities in relation to the conflict.
