CISA and the FBI jointly reported that state-sponsored hacking groups penetrated networks belonging to US water utilities, electrical grid operators, and financial market infrastructure at record rates in the first quarter of 2026. Many of the intrusions are characterized as pre-positioning rather than active attacks, with adversaries establishing persistent access that can be activated for disruption at a time of their choosing.
The threat has prompted a classified briefing cycle to critical infrastructure operators and a new federal initiative providing no-cost cybersecurity assessments to utilities serving small and mid-size communities that lack internal security capabilities. CISA Director Jen Easterly emphasized that the nation's critical infrastructure is operating on a threat level that requires treating cybersecurity as fundamental operational infrastructure rather than an IT department problem.
