Protect your Tesla from Flipper Zero hack with these tips.

Security Researchers Warn Tesla Drivers May Fall into Hackers' Control, Suggest Avoiding Free Wi-Fi to Prevent Vulnerability

🚗 Unlocking Vehicles: Convenience vs. Vulnerability


While unlocking vehicles with smartphone apps rather than physical keys offers significant convenience benefits, it also significantly expands the attack surface. Security researchers have recently discovered a method that uses a $169 Flipper Zero device to deceive Tesla owners into relinquishing control of their cars to a malicious third party, enabling the vehicle to be unlocked and even driven away. 😱

Gaining Access with Fake Wi-Fi Networks

Researchers Tommy Mysk and Talal Haj Bakry of Mysk Inc have devised a method for fooling a Tesla owner into handing over their vehicle’s login credentials. The attacker would use the Flipper Zero and a Wi-Fi development board to broadcast a fake Tesla guest Wi-Fi network login page. “Tesla Guest” is the name given to Wi-Fi networks at service centers. This fake login page captures all the owner’s information entered – username, password, and two-factor authentication code – and displays it on the Flipper Zero. 😮

Here’s a walkthrough of the process:

Bypassing Two-Factor Authentication

This attack also bypasses two-factor authentication because the fake Tesla guest Wi-Fi network login page requests the two-factor authentication code that the attacker then uses to access the account. Consequently, the hacker must work rapidly to request and use the code to gain access to the account. 💨

Is the Physical Keycard Enough?

One might wonder if the physical keycard provided by Tesla is enough to protect against this attack. According to the user manual, it should be, as the key card is used to “authenticate” phone keys to work with the Model 3 and to add or remove other keys. However, as per Mysk’s findings, this is not the case. 😓

Mysk reached out to Tesla for comment on this vulnerability and was told that the company had “investigated and determined that this is the intended behavior.” This response raises concerns regarding Tesla’s stance on the matter. Mysk recommends that Tesla make it mandatory to use the key card to create new keys in the app and that owners should be notified when new keys are created.

Protecting Yourself from the Attack

Now, it’s time to address the burning question of how to protect yourself from this type of attack. First, don’t panic! This attack is unlikely to be widespread. The attacker would need to be within close proximity of your vehicle and carry out the login to your Tesla account in real-time. 🙅‍♂️

Second, note that you do not need to enter your two-factor authentication code to be able to connect to Tesla’s guest Wi-Fi account. If in doubt, it’s best to avoid using free Wi-Fi.

Q&A: Answering Your Concerns

Q1: Can other tools be used to carry out this attack?

While Mysk and Bakry used a Flipper Zero in their demonstration, other tools could also be employed. For example, a Wi-Fi Pineapple or Wi-Fi Nugget could potentially be used to execute a similar attack.

Q2: Are there any additional steps Tesla owners can take to secure their vehicles?

Besides using the key card to create new keys in the app and receiving notifications for new key creations, Tesla owners can enhance their security by practicing good digital hygiene. This includes regularly updating their vehicle’s software, avoiding connecting to unfamiliar Wi-Fi networks, and setting up strong, unique passwords for their Tesla accounts.

Q3: Could this attack be executed on other vehicle brands equipped with smartphone unlocking features?

While this specific demonstration targeted Tesla vehicles, it highlights the potential vulnerabilities of any vehicles using smartphone apps for unlocking. As technology evolves, it’s crucial for all automobile manufacturers to prioritize the security of their digital access systems.

Wrapping Up

While the convenience of unlocking vehicles with smartphone apps is undeniably appealing, it’s essential to remain cautious about the potential security risks. Tesla owners, in particular, should be aware of the vulnerability demonstrated by Mysk and Bakry. By implementing recommended precautions and staying informed about potential threats and solutions, vehicle owners can enjoy the benefits of modern technology without compromising on safety. Stay safe and happy driving! 😊
