Two new security weaknesses discovered in several electric vehicle (EV) charging systems could be exploited to remotely shut down charging stations and even expose them to data and energy theft.

The findings, which come from Israel-based SaiFlow, once again demonstrate the potential risks facing the EV charging infrastructure.

The issues have been identified in version 1.6J of the Open Charge Point Protocol (OCPP) standard that uses WebSockets for communication between EV charging stations and the Charging Station Management System (CSMS) providers. The current version of OCPP is 2.0.1.
