As electric vehicle (EV) charging infrastructure rushes to keep pace with the dramatic rise in sales of electric vehicles in the United States, cyberattackers and security researchers alike have already started focusing on security weaknesses in the infrastructure.

In February, researchers with energy-network cybersecurity firm Saiflow discovered two vulnerabilities in the Open Charge Point Protocol (OCPP) that could be used in a distributed denial-of-service (DDoS) attack and to steal sensitive information. And the Idaho National Laboratory recently found that every charger it examined — more formally known as Electric Vehicle Supply Equipment (EVSE) — was running outdated versions of Linux, had unnecessary services, and allowed many services to run as root, according to a survey of EV charging vulnerability research in the journal Energies.
