SLAC-EV CHARGING (IMAGE)
Caption
SwRI identified security vulnerabilities in the Signal Level Attenuation Characterization (SLAC) protocol governing the connection process between a supply equipment communication controller (SECC) and electric vehicle communication controller (EVCC). SwRI developed a machine-in-the-middle (MitM) device to tap into the appropriate line in the charger cable. Researchers injected signals that led to full control over the communications channel. By spoofing a second charger with superior attenuation, an attacker can bridge the charger connection to intercept traffic.
