Iran-aligned hackers have exploited and disrupted operational technology control systems embedded in multiple U.S. critical infrastructure sectors, targeting equipment manufactured by Rockwell Automation, according to an advisory issued Tuesday. The hackers have set their sights on the company’s Allen-Bradley line of programmable logic controllers, or PLCs, which are digital computers that interface with operational equipment to monitor and automate industrial processes like water treatment, power generation and manufacturing. The cyber intrusions have, in some cases, resulted in operational disruption and financial loss, according to the assessment signed by the Cybersecurity and Infrastructure Security Agency, FBI, NSA, EPA, the Department of Energy and U.S. Cyber Command’s Cyber National Mission Force. The disruptions occurred by manipulating data on human-machine interfaces and on supervisory control and data acquisition, or SCADA, displays, as well as harmful interactions with project files, it adds.
