4,000 US Industrial Devices Exposed

4,000 US Industrial Devices Exposed

Nearly 4,000 Rockwell Automation programmable logic controllers operating inside U.S. critical infrastructure networks remain exposed to the internet, constituting the primary attack surface targeted by Iranian-linked threat actors in ongoing operations against industrial systems.

PLCs of this type govern physical processes in energy, water, and manufacturing sectors. Internet-exposed industrial controllers represent a structural vulnerability: devices designed for isolated operational environments but connected to public networks without adequate segmentation or authentication controls.

Iranian-affiliated groups have demonstrated sustained focus on U.S. operational technology infrastructure. Targeting Rockwell hardware specifically indicates adversary familiarity with the vendor's deployment footprint across high-value sectors.
