Critical Infrastructure Attacks

Critical infrastructure — the power grids, water systems, financial networks, telecommunications, transportation, and healthcare systems that underpin modern civilization — has become the primary battleground for state-sponsored cyber operations. Unlike espionage or financial crime, attacks on critical infrastructure carry the potential for mass civilian impact, making them a red line issue in cyber policy.

The threat is multi-dimensional. Russian APTs (Sandworm) have demonstrated willingness to cause real outages — Ukraine's power grid was attacked in 2015 and 2016, leaving hundreds of thousands without heat in winter. China's Volt Typhoon has been pre-positioning in US water, energy, and telecommunications networks — not for immediate attack, but to hold capabilities ready for a future crisis over Taiwan or another flashpoint. Iranian actors have targeted Israeli and US water treatment systems. The Colonial Pipeline ransomware attack demonstrated that criminal actors can cause fuel supply crises affecting an entire US region.

The convergence of IT and OT (operational technology) systems — driven by industrial digitization and IoT adoption — has dramatically expanded the attack surface of critical infrastructure. PLCs, SCADA systems, and industrial sensors designed decades ago for isolated environments are now internet-connected, creating systemic vulnerability that is extremely difficult to remediate without operational disruption.
