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.

New enemy for fast charging stations; Brokenwire
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.
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.
