In 2021, Colonial Pipeline, a critical fuel supplier for the U.S. East Coast (45% of regional fuel), fell victim to a **ransomware attack** targeting its **IT billing network**. The attack forced a **complete shutdown of pipeline operations** for several days, triggering fuel shortages, panic buying, and regional economic disruption. The incident was not a direct OT breach but demonstrated how IT compromises can cascade into **physical operational paralysis**—a hallmark of Industry 4.0 risks. The company paid a **$4.4 million ransom** (partially recovered later) to restore systems. The attack exposed vulnerabilities in IT-OT convergence, where cyber threats transcend data theft to **disrupt physical infrastructure**, aligning with broader trends of adversaries weaponizing digital access to cripple critical services. The downtime cost exceeded **$2.3 million per hour** in lost revenue and secondary economic impacts, underscoring the strategic threat to national infrastructure.
