U.S. warns of AI-driven attacks on Siemens PLCs
🔒 U.S. cybersecurity agencies issued a joint advisory warning that threat actors are using AI-generated Python scripts to exploit Siemens S7 Series programmable logic controllers (PLCs) within U.S. critical infrastructure. The agencies—NSA, CISA, FBI, DOE, and EPA—noted ongoing activity that targets exposed PLCs by abusing vulnerabilities, outdated software, and weak authentication to gain read/write access and disguise tools as legitimate OT monitoring software. Operators are urged to inventory devices, apply updates, block internet access, and strengthen monitoring and access controls to reduce risk.
