The trend caught the eye of researchers at a top government cybersecurity lab, who have embarked on a multiyear project to learn how hacking a charging station might disrupt the quality and flow of power through a local grid. In a video, Rohde approached a charging station and ran an attack on the human machine interface (HMI), which affects the charging process by communicating with a control system. He executed a spoofing command to trick the charging station into thinking the vehicle was 90-percent charged when it was really at a third of its power. “If we can get a foothold on the HMI, then the way this system is currently architected is that HMI has full control of everything in the [power] cabinet” that is central to the charging station, Rohde told CyberScoop. By commandeering the charging station, Rohde’s hacking demo ramped up the total harmonic distortion of the power flowing through the station.
