A live lab demonstrates a purchasable VM stack (Fortified graphical realism) that simulates a chemical plant, exposes Modbus traffic, and lets an attacker read and write registers via Wireshark captures, ARP spoofing from Kali, and a Metasploit modbus client; queries generated with ChatGPT plus Shodan find internet‑exposed HMIs; the demo changes setpoints and trips the simulated boiler—proof of concept works end‑to‑end and shows how trivial tooling maps to physical‑process impact.
