Critical Infrastructure Under Attack: What Recent Cyber Incidents Have in Common
Recent cyberattacks against critical infrastructure reveal a troubling pattern: attackers are repeatedly exploiting Internet-exposed devices, weak remote-access controls, legacy technology, and insufficient OT visibility to move closer to physical operations. From automatic tank gauges and network routers to water utility control systems, these incidents demonstrate why critical-infrastructure organizations must strengthen segmentation, authentication, monitoring, asset inventories, and operational resilience.
