Research Summary

As the adoption of electric vehicles (EVs) and connected car technologies accelerates, the cybersecurity of EV charging infrastructure and connected car networks has become a critical concern. These systems are integral to modern transportation, and their security is paramount to prevent disruptions, data breaches, and safety risks. This report delves into the various cybersecurity threats targeting EV charging infrastructure, their potential impacts, and the strategies to mitigate these risks.

Man-in-the-Middle (MitM) Attacks

MitM attacks pose a significant threat to EV charging infrastructure. Cybercriminals intercept communications between the EV charger and the network, potentially gaining unauthorized access to sensitive data such as payment information, user credentials, and operational data. This can lead to data theft and unauthorized control over the charging process. Implementing strong encryption and authentication mechanisms is crucial to mitigate these risks.

Malware and Ransomware

Malicious software, including ransomware, can disrupt EV charging operations, encrypt data for ransom, or exfiltrate sensitive information. Notable incidents like the "BrokenWire Hack" have demonstrated the vulnerability of EV charging stations to such attacks. Regular firmware updates and robust backup and recovery procedures are essential to defend against malware and ransomware threats.

Device Disabling and Overcharging

Cyber attackers can disable EV chargers or manipulate them to overcharge vehicles, potentially damaging batteries or causing fires. Such attacks can disrupt fleet operations and pose significant safety risks. Ensuring that administrative controls are secure and implementing physical security measures can help prevent these types of attacks.

Administrative Control Breaches

Weak or absent security measures, such as inadequate authentication and encryption, can allow hackers to gain access to a charger's administrative controls. This can lead to unauthorized changes in settings, disabling essential functions, and creating operational hazards. Regular security audits and the implementation of strong authentication protocols are necessary to protect administrative controls.

Data Theft and Unauthorized Access

Vulnerable charging stations can be exploited to steal sensitive corporate information or gain unauthorized access to broader networks. This can lead to extensive network attacks. Network segmentation and continuous monitoring of networked devices are effective strategies to mitigate these risks.
