U.S. cybersecurity agencies warn that threat actors are using AI-generated scripts to exploit Siemens S7 Series programmable logic controllers (PLCs) in U.S. critical infrastructure.
PLCs are industrial computers used to automate and control machinery and physical processes in factories and other critical infrastructure.
The NSA, CISA, FBI, Department of Energy, and Environmental Protection Agency issued the joint advisory Wednesday, saying the attacks are ongoing.
"This advisory relates to an active threat to Siemens S7 Series programmable logic controllers (PLCs)," reads the advisory.
"However, ongoing PLC targeting activity is broader than Siemens PLCs. All PLC owners and operators should apply relevant mitigations to reduce the risk to their devices and systems."
