In a groundbreaking discovery, a team of researchers from Technische Universität Berlin in Germany managed to successfully jailbreak a Tesla Model 3, gaining access to in-car features that are usually paid upgrades. This feat was accomplished through a clever technique called “voltage glitching,” which involved manipulating the supply voltage of the AMD processor running the car’s infotainment system. While this hack required physical access to the vehicle, it has raised concerns about potential security vulnerabilities that could be exploited in the future.

The Hack

The three white hat hackers involved in this project achieved the jailbreak by exploiting a flaw in the Tesla Model 3’s hardware. By manipulating the supply voltage at the right moment, they were able to trick the CPU into executing their own code, thereby bypassing restrictions on certain in-car features. This allowed them to unlock access to features like heated rear seats without the need to pay for official upgrades.

Exploring the Possibilities

While the primary motive behind the jailbreak was to grant owners access to features they already had in their vehicles, the researchers went a step further and extracted the encryption key used to authenticate the car to Tesla’s network. With this key in hand, they were able to access critical personal information stored within the vehicle. The information included contact details, call logs, calendar appointments, visited locations, Wi-Fi passwords, and session tokens from email accounts.

The Potential Security Implications

Although the researchers claim to have extracted sensitive information from the car’s system, they acknowledge that this data could only be accessed by someone with physical access to the vehicle. However, the discovery raises concerns about potential security risks associated with hardware-based attacks. If hackers were to gain physical access to a Tesla Model 3, they could potentially exploit similar vulnerabilities to extract personal data from the vehicle.

Tesla’s Response

Upon learning of the researchers’ successful jailbreak, Tesla will likely be working diligently to address the issue. The most effective defense against such hardware-based attacks would be to replace the vulnerable hardware components in question. By eliminating the vulnerability at its source, Tesla can ensure a higher level of security for its vehicles and prevent unauthorized access to sensitive data.

Ethical Implications

While the researchers in this case were white hat hackers, meaning they had good intentions and reported their findings to Tesla, their discovery could potentially encourage unethical hackers to exploit similar vulnerabilities for malicious purposes. Therefore, it is vital for automakers and technology companies to prioritize security measures and continuously update their systems to stay ahead of potential threats.


The successful jailbreak of a Tesla Model 3 by a team of researchers highlights the importance of cybersecurity in the automotive industry. While this particular hack required physical access to the vehicle, it serves as a reminder for manufacturers to take all necessary precautions to safeguard their products against potential vulnerabilities. As technology continues to evolve, so do the methods used by hackers to exploit weaknesses. By investing in robust security measures and staying vigilant, automakers can ensure the safety and privacy of their customers’ data, as well as the integrity of their vehicles.
