US and UK infrastructure targeted in suspected Iran-linked's
Overview
Since the late‑July 2026 intrusion that knocked a Minnesota water plant offline, coordinated attacks on internet‑exposed Rockwell Automation/Allen‑Bradley PLCs have been reported in at least twelve U.S. states, including Michigan, Georgia, New Jersey, and South Dakota. Utilities have lost monitoring and control, experienced pressure drops, localized flooding and, in some cases, boil‑water advisories, though no drinking‑water contamination has been confirmed. The FBI, EPA and CISA issued a joint advisory warning that the campaign, suspected to involve Iranian‑linked actors, may exploit the Modbus‑TCP denial‑of‑service flaw CVE‑2017‑16740 to enable unauthenticated reprogramming.
Recent developments indicate the scope of Iranian-linked activity may extend beyond U.S. water utilities. In the United Kingdom, a small power generator was reportedly forced offline for four days in July 2026, though officials stated there was no threat to the national power supply. In the U.S., attackers have reportedly gained remote control over pumps and valves in states such as Arkansas, forcing utilities to switch to manual operations.
The situation has escalated alongside physical military tensions. Following U.S. military strikes near the Strait of Hormuz—described by President Donald Trump as a response to Iranian sea mines and missile attacks on a U.S. base in Jordan—the confrontation has expanded into cyberspace. Hackers linked to Iran have reportedly attempted to penetrate critical U.S. infrastructure, including water, energy, and telecommunications. While these attempts represent a shift toward targeting civilian-facing physical processes, they have not yet caused major service disruptions. Separately, the FBI continues to investigate an opportunistic data breach at Kansas-based Micro‑Comm, which remains distinct from the broader infrastructure campaign.
