On February 28, 2026, the United States and Israel launched Operation Epic Fury (U.S.) and Operation Roaring Lion (Israel), a coordinated military and cyber campaign targeting Iranian military installations, IRGC leadership, and government infrastructure. U.S. Cyber Command was designated the “first mover,” with cyber operations beginning before any kinetic weapons were deployed. In the first 48 hours, U.S. and allied forces struck more than 1,250 targets across Iran, while Israel conducted what has been described as the largest cyberattack in history, collapsing Iran’s internet connectivity to 1-4% of normal levels through multi-layered attacks on BGP routing, DNS infrastructure, and SCADA/ICS systems.
