Programmable Logic Controllers (PLCs) are field-level devices in OT/ICS/SCADA systems that read sensors, execute logic and drive real machinery. Compromise a PLC and you can overspeed a pump, slam a valve shut or make a safety interlock ignore a fault. In this workshop you will hunt down and exploit 5 security issues straight out of real-world PLC deployments. Requirement: Laptop with Wi-Fi and Ubuntu 24.04 VM (amd64/arm64).
