SCADA Malware Demo Kit test 1

Worked on part of a demo kit showing PLC malware and how to prevent it. There is a Nano 10 PLC hooked up to a green and red LED, a buzzer and a FAN. All operating on 24VDC. I wrote a HMI that talks Modbus TCP to the Nano 10. The HMI is running on a raspberry PI. The operator can use the HMI to turn the individual coils on in the nano 10. My malware turns the operator PC into an attack box and makes the PLC go crazy. We use a Check Point 2200 to detect and block the malware from attacking the PLC while allowing the legitimate HMI traffic through.
