The Federal Bureau of Investigation (FBI) and Environmental Protection Agency (EPA) are issuing this Public Service Announcement (PSA) to warn critical infrastructure asset owners and operators that malicious cyber actors (MCAs) are conducting cyber attacks targeting Operational Technology (OT) devices, including Rockwell Automation/Allen-Bradley Programmable Logic Controllers (PLCs), specifically MicroLogix 1100 and 1400 series. Since 27 July 2026, Water and Wastewater Sector (WWS) utility companies in at least seven states have reported incidents to the FBI, and some of that activity degraded water operations. While the FBI has only observed this behavior with the referenced Rockwell PLCs, similar considerations should also be made with other branded PLCs.

    This is probably fake fear mongering propaganda from the feds designed to:

    1.) manufacture consent for their war of choice 2.) excuse problems from ever crumbling infrastructure here in the US

    That being said, Iran has every right to do this and worse, given what we keep doing to them.

      Its very possibly real. I work with a similar Rockwell PLC and advise all my customers not to allow WAN communication with the devices because of this very issue. The security in the PLC program widely varies depending on who programmed it and most places are not willing to change default passwords. Its a receipt for disaster.
