Security Evaluation
1. Device Security
| Criterion
|
Value
|
Proof
|
Comment
|
| Known hardware tampering
|
Rare
|
🔗 Proof
|
Hardware modification and custom firmware flash are possible but require physical disassembly and bypass of secure boot; not widespread.
|
| Known vulnerabilities
|
Rare
|
🔗 Proof
|
Several historical CVEs for Tesla infotainment and telematics; most patched by OTA. Public exploits targeting MCU2 specifically are limited.
|
| Prior attacks
|
Rare
|
🔗 Proof
|
Demonstrated security research attacks exist in academic/security conferences; no large-scale mass exploitation in the wild.
|
| Updatability
|
Very common
|
🔗 Proof
|
Supports remote OTA firmware and infotainment software updates from Tesla backend.
|
| Category Score
|
Score: 2 / 3
|
2. System Security
| Criterion
|
Value
|
Proof
|
Comment
|
| Authentication with other systems
|
Partial
|
🔗 Proof
|
Authenticates to Tesla cloud backend, paired with owner Tesla account and mobile app; integrates with vehicle CAN ECU authentication.
|
| Communications
|
Encrypted with up-to-date encryption
|
🔗 Proof
|
TLS for cloud communication; BLE/WiFi/CAN use automotive-grade encryption and authentication where implemented.
|
| Storage
|
Encrypted with up-to-date encryption
|
🔗 Proof
|
User data, navigation, account credentials stored encrypted at rest.
|
| Category Score
|
Score: 2 / 3
|
3. User Authentication
| Criterion
|
Value
|
Proof
|
Comment
|
| Account management
|
Basic
|
🔗 Proof
|
User identity managed centrally via Tesla cloud account; vehicle MCU is a client device.
|
| Authentication
|
Secure
|
🔗 Proof
|
Secure boot, signed firmware, account-bound pairing, key-fob authentication.
|
| Brute-force protection
|
Exist
|
🔗 Proof
|
Rate limiting on login, pairing and remote command endpoints.
|
| Event logging
|
Partial logging
|
🔗 Proof
|
Syncs telemetry, access and command logs to Tesla cloud; local onboard log limited.
|
| Passwords
|
Require change after setup with complexity requirements
|
🔗 Proof
|
Password policy and rotation enforced on Tesla cloud account side.

Tesla Model 3 MCU2 (1507275-00-D) is the second-generation infotainment media control unit for Tesla Model 3, powered by Intel Atom A3950 on a custom Linux Tesla OS. It connects to the Tesla cloud and mobile app over LTE/Wi‑Fi/Bluetooth and communicates with vehicle ECUs over CAN/Ethernet. It uses signed firmware and secure boot, supports regular OTA updates, and stores user data with encryption. Security research has demonstrated physical and remote attack vectors on this platform, though real-world widespread exploitation remains rare.
