Iran-Linked Hackers Disrupt US Critical Infrastructure via PLC Attacks

Federal agencies have issued warnings that Iran-linked threat actors are actively targeting and disrupting U.S. critical infrastructure by directly manipulating programmable logic controllers (PLCs) and SCADA systems. These attacks have triggered operational disruptions across multiple critical sectors, marking a significant escalation in nation-state cyber operations against operational technology environments. The threat actors are leveraging their access to compromise industrial control systems, potentially causing physical impacts to power grids, water systems, and manufacturing operations. Security teams managing OT infrastructure should immediately review PLC configurations, implement network segmentation between IT and OT systems, enable logging and monitoring on all control devices, and conduct thorough assessments to detect any unauthorized modifications or anomalies indicative of compromise.

Federal agencies warn attackers are manipulating PLC and SCADA systems across multiple sectors, triggering operational disruptions and raising concerns over broader OT targeting. The post Iran-Linked Hackers Disrupt US Critical Infrastructure via PLC Attacks appeared first on SecurityWeek .
