How Iranian Cyber Operations Target the Hidden Infrastructure Behind U.S. Military Power
Iranian cyber operations are increasingly targeting the interconnected civilian infrastructure that supports U.S. military operations, including commercial railroads, ports, utilities, and defense contractors. Rather than pursuing catastrophic single attacks, Iranian threat groups are conducting persistent, volume-based campaigns across multiple smaller targets to strain response capabilities and disrupt military logistics chains. Recent attacks on water utilities across 12 states and a four-day power plant outage in the UK demonstrate this strategy of imposing cumulative operational strain rather than seeking headline-grabbing breaches. This threat model reflects Iran's adaptation to prolonged conflict scenarios, where creating sustained disruption across military-supporting infrastructure becomes more strategically valuable than traditional espionage or single-point failures.
