Project Robus is a search for vulnerabilities in ICS/SCADA protocol stack implementations. Most research and commercial tools to date have focused on the PLC/RTU/controller (server). Project Robus tests both the RTU server and the master (client) sides of DNP3 and Modbus protocol stack implementations. Attacking the DNP3 master in the control center can eliminate the ability to monitor and control an entire SCADA system, such as an entire electric transmission or distribution system … all from accessing a serial or IP connection in one unmanned substation.
