SwRI developed an adversary-in-the-middle device with a modified combined charging system to test the cyber resiliency of ISO 15118-compliant vehicle-to-grid, direct current fast charging systems. The high-voltage technology relies on power line communications (PLC) to transmit smart-grid data between vehicles and charging equipment. SwRI researchers exploited vulnerabilities in the PLC layer, gaining access to network keys and digital addresses on both the charger and the vehicle.
