Electric Vehicle Fast Charging Stations Face Critical Vulnerability

Researchers at Oxford University and Switzerland's Armaruisse Federal Security Procurement Agency have discovered a hacking method that can be used to remotely cut off communication between electric vehicles and chargers. Alev Akkoyunlu, Operations Director of Laykon Bilişim, said that this attack method, called Brokenwire, threatens approximately 12 million electric vehicles in use today, as it enables wireless connection to the Combined Charging System (CCS), which is widely used in electric vehicles.

A new attack method has been discovered against the Combined Charging System (CCS), used in 12 million electric cars today, that allows third parties to remotely interrupt the charging process. Researchers from Oxford University and Switzerland's Armaruisse Federal Security Procurement Agency called the hacking method Brokenwire, which can cut communication between electric vehicles and chargers from a distance of 47 meters. Laykon IT Operations Director Alev Akkoyunlu stated that the attack method is not only limited to cars, but also threatens electric ships, aircraft and heavy-duty vehicles. The Combined Charging System (CCS), which has been hacked, stands out as one of the most used DC fast charging technologies today.

Electric Vehicle Charge Can Be Cut Off From An Upstairs Of The Apartment

The newly discovered hacking attack, called Brokenwire, can be carried out from a distance of 47 meters from electric vehicles. While this distance almost coincides with different floors of a building, it has been proven that it is possible to carry out the attack while driving by the charging station. Laykon IT Operations Director Alev Akkoyunlu also stated that the attack can only be used to interrupt the charging session and will not cause any damage to the targeted systems. Akkoyunlu, one of the most worrying aspects of the attack; emphasized that it can affect a large fleet at the same time as well as individual users. The attack renders the station unusable until the transmitter is found and disabled. Therefore, after the attack has stopped, it must be manually reconnected with the charger.

“Can Be Done With Minimum Technical Knowledge”

It is a known fact that the mobile phone feature leaves many electric cars vulnerable today, but it was discovered with this research that charging technologies are also a target. Researchers have revealed that attacks that disable the connection of electric vehicles with charging stations can be carried out with ready-to-use hardware and minimal technical knowledge. In addition, this attack method not only puts electric cars at risk, but also affects electric ships, aircraft, heavy-duty vehicles. The method, which can also affect critical public vehicles such as electric ambulances, may interrupt the charging process and lead to life-threatening dangers. The detailed findings of the study were shared with the relevant manufacturers, but have not yet been made public until a counter-method has been developed to prevent abuse. Only DC fast chargers are included in the report. Therefore, those using AC charging are not affected by the vulnerability.
