Iran-Linked Hackers Disrupt U.S. Critical Infrastructure via PLC Attacks

Federal agencies reported that Iran-linked hackers are manipulating programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) systems to disrupt U.S. critical infrastructure across multiple sectors. The attacks have caused operational disruptions, raising concerns about broader targeting of operational technology (OT) environments. No specific dates, technical indicators, or affected organizations were disclosed in the notice. The activity underscores heightened risks to industrial control systems (ICS) from state-sponsored threat actors. The warning highlights the potential for further escalation in OT-focused cyberattacks.
