Bottom line: The joint advisory highlights the increasing threat of AI-generated scripts to exploit Siemens S7 PLCs in critical industrial processes.
What's happening: U.S. agencies have identified a threat actor targeting Siemens S7 Series PLCs in the United States, Germany, and other countries, including the German power grid operator E.ON and the U.S. power grid operator Exelon. The advisory highlights an emerging threat actor using AI-generated scripts to manipulate Siemens S7 PLCs, which control industrial processes in critical infrastructure, such as power grids and water treatment facilities.
What to do: CISA and NSA recommend that security leaders implement NTP synchronization to detect anomalies in PLC behavior and follow up with regular security audits to ensure the integrity
