The modern car has ceased to be just a means of transportation with an internal combustion engine, but has become a very complex computer on wheels, controlled by software code. Owners of electric cars Tesla, created by Elon Musk's company, are often faced with news about new features that come over the air, but rarely think about the dark side of this digital revolution. Cybercrime evolves with technology, and automotive systems become a tasty target for hackers from all over the world.
The threat of hacking concerns not only the entertainment system or personal data in the profile, but also the physical safety of the driver. Remote control locks, access to surveillance cameras and even tampering with the brake system - this is no longer the plot of a science fiction film, but a reality that information security specialists are struggling with. Understanding attack mechanisms allows owners Tesla Model 3 and Model Y better protect your property.
In this article we will examine in detail known cases cyber attacks, protection methods and how the company Tesla Inc. responds to detected vulnerabilities. You need to be aware of the risks associated with connecting your vehicle to public Wi-Fi networks and using third-party applications. The most critical vulnerability in recent years is the ability to clone a key fob signal using a cheap repeater, which allows you to steal a car in a matter of seconds without damaging the locks.
Software vulnerabilities and remote access
The basis of the functionality of electric vehicles Tesla is based on an operating system similar to Linux, which manages all processes in the machine. Hackers are constantly looking for holes in the code to gain root rights (superuser rights) over the vehicle system. Obtaining such access allows you to change operating parameters battery, disable security systems, or simply demonstrate hacking capabilities at conferences.
One attack method involves exploiting vulnerabilities in the browser built into the multimedia system. By visiting a specially prepared malicious website, the car can receive a command to load exploit. Security researchers have repeatedly demonstrated how a vulnerability in a browser can gain access to a car's internal network, known as the CAN bus.
What is a CAN bus?
CAN (Controller Area Network) is an industrial network standard designed for the exchange of data between electronic control units in a vehicle. Signals from pedals, speed sensors, braking and engine control systems are transmitted through it.
Company Tesla actively uses the program Bounty Program, paying rewards to white hat hackers for finding vulnerabilities. This allows you to close security holes before they are exploited by attackers. However, owners should remember that installing unofficial software or jailbreak the system removes the guarantee and opens the door to real attacks.
Check your access history in the Tesla app regularly. If you see logins from an unfamiliar device or location, immediately change your password and enable two-factor authentication.
Hacking a mobile application and stealing it through the cloud
The most common attack vector in recent years has become not the car itself, but the owner’s account in a mobile application. Attackers use methods phishingby sending fake emails claiming to be from support Tesla. The purpose of such letters is to lure out the login and password for the account, which gives complete control over the machine.
Once a criminal gains access to an account, he can track geolocation car, open and close doors, start the engine and even change climate control settings. In some cases, thefts have been recorded where the car was opened and started remotely through a server, without using a physical key or the owner’s smartphone next to the car.
☑️ Account security check
Particularly dangerous is the use of public Wi-Fi networks to log into an application or update a car. Transmitted data may be intercepted if the connection is not properly secured encryption. It is recommended to use only mobile Internet or trusted networks for critical account operations.
⚠️ Attention: Never click on links in SMS or letters that talk about blocking your account or the need to urgently update your card details. Official support Tesla does not prompt for passwords in this way.
Attacks on autopilot and camera systems
System Autopilot and promising Full Self-Driving (FSD) rely heavily on computer vision and neural networks. Security researchers have proven that it is possible to fool car cameras using physical objects or projections. Stickers on road markings or special patterns on pedestrians' clothing can cause a car to ignore speed limits or not noticing obstacles.
Moreover, there is a risk of remote access to external and internal surveillance cameras. Theoretically, an attacker with access to the system can broadcast video from car cameras in real time, violating confidentiality owner. Although Tesla claims that data is processed locally, the risks of leaks through cloud servers during synchronization remain a hot topic for discussion.
To protect against visual attacks, it is necessary to monitor software updates, since Tesla Constantly improves recognition algorithms. It is also important to understand that autopilot is a driver assistance system, and not a full-fledged autonomous robot, and the responsibility for controlling the traffic situation always lies with the person.
Relay attacks and key cloning
One of the most popular theft methods Tesla Model 3 and Model Y - This is a relay attack. Attackers use two devices: one is placed near the car door, and the second is placed near the owner's key fob, which may be located in the house or pocket. Signal Bluetooth Low Energy (BLE) is transmitted between devices, and the car “thinks” the key is nearby.
This method does not require code breaking or complex calculations; it exploits the very principle of the wireless dongle. The machine receives the correct cryptographic response from the key fob through an intermediary and allows opening doors and starting the engine. The cost of equipment for such an attack has recently dropped significantly, making the method accessible to ordinary hijackers.
| Threat type | Required equipment | Implementation complexity | Protection efficiency |
|---|---|---|---|
| Signal relay (BLE) | Two radio modules (for example, Flipper Zero, HackRF) | Low | Key shielding or disabling required |
| Phishing account | Computer, fake website | Medium (requires social engineering) | High (with 2FA enabled) |
| Hacking via Wi-Fi | Laptop, antenna, exploits | High | High (with updated firmware) |
| Physical access to OBD | Diagnostic scanner, interior access | Average | Medium (requires physical access) |
To counter this Tesla introduced support for key cards and smartphones with additional verification. However, the most reliable method of protection remains physical shielding of the key fob or the use of the “Parking Mode” function, which requires entering a PIN code on the screen to start driving.
Protection measures and security settings
Owners of electric cars must independently activate a number of safety features, which may be disabled by default or not configured optimally. The first step should be activation PIN code for driving. This feature requires you to enter a 4-digit code on the touch screen before each move, making theft useless even if the locks are successfully picked.
The second most important step is setting up data access. In the security menu, you can disable the transmission of vehicle usage data, which will improve anonymity. It is also recommended to regularly check the list of connected phones in the “Devices” section and delete those that are no longer used or are suspicious.
Using a key card instead of a key fob with constant signal emission completely eliminates the risk of a relay attack, since the card does not emit a signal until it is applied to the rack.
Physical protection should not be neglected either. Installing a GSM tracker hidden deep in the body, or an engine blocker that is not associated with standard electronics, will create an additional level of complexity for hijackers. An integrated approach combines digital settings and mechanical protection.
⚠️ Warning: The Remote Start feature is convenient, but it is also an attack vector. If you don't plan to use phone launch right now, it's best to keep this option disabled in your security settings.
Cybersecurity Outlook for Electric Vehicles
The future of automotive safety lies in artificial intelligence and machine learning. Tesla and other manufacturers are moving to an architecture where each component has its own digital signature. This means that even if physically connected to CAN bus, a third-party device will not be able to send a command unless it is authorized by the factory's cryptographic keys.
The concept of “Zero Trust” in automotive networks is also developing. The system constantly checks the integrity of the software and the behavior of the nodes. If the control unit begins to behave strangely (for example, requests access to data unnecessarily), it can be automatically isolated from the network to diagnostics.
Owners should follow news in the field cybersecurity, as the threat landscape changes annually. What was safe yesterday may become vulnerable today. Responsible use of technology and compliance with digital hygiene are key to the safe operation of a high-tech vehicle.
When selling your car, be sure to perform a Factory Reset and remove the car from your Tesla account to prevent the new owner from gaining access to your driving history and home Wi-Fi.
Frequently asked questions (FAQ)
Is it possible to completely disable the Internet in Tesla to avoid hacking?
