Hackers could target public EV charging stations or home chargers to steal data or execute a DoS or denial-of-service attack. The former could lead to more exploits like bank account information, credit cards, user IDs, and passwords. However, a DoS attack could shut down an entire EV charging network and disrupt services to millions of EV owners. Ukrainian hackers infiltrated Russian EV charging stations in 2022, displaying derogatory messages against Russian President Vladimir Putin and disabling services to all chargers from Moscow to St. Petersburg.
Unfortunately, there’s not much that users can do to ensure 100% protection against EV charging hacks. Unlike petrol cars that fill the fuel without connecting to the car’s system, an EV charger establishes a data connection with the vehicle, making it vulnerable to hacking by exploiting software vulnerabilities. The most that EV buyers could do is avoid installing cheaper EV home chargers from lesser-known brands that could have software flaws, subpar encryption, and weak authentication.
It’s also a good idea not to connect your home EV chargers to the internet to safeguard against potential hacking. Meanwhile, the Biden administration passed the Bipartisan Infrastructure Law in 2021, which includes up to $7.5 billion to expand EV charging networks and improve cybersecurity measures to safeguard against external threats. And in 2023, the Federal Highway Administration passed a ruling that requires states to implement specific cyber requirements for all new chargers funded under the Bipartisan Infrastructure Law.
