Iranian hackers are targeting American critical infrastructure, US agencies warn

U.S. agencies warn Iran-backed hackers are escalating attacks on American critical infrastructure.

A joint advisory by the FBI, NSA, CISA and DOE was published Tuesday.

Targets include water and wastewater utilities, energy systems, and local government facilities.

Hackers targeted programmable logic controllers and SCADA devices, causing operational disruption and financial loss.

Agencies say hackers can alter device displays and configuration files; escalation may be linked to the U.S.-Israel war with Iran that began February 28.
