S800 Vehicle Network Security Testing Framework
Skill by ara.so — Security Skills collection.
Overview
S800 is a vehicle network security testing framework designed for automotive security researchers and penetration testers. It provides tools for analyzing, testing, and securing automotive networks including CAN bus, LIN, FlexRay, and other vehicle communication protocols. The framework enables security assessment of Electronic Control Units (ECUs), protocol fuzzing, traffic analysis, and vulnerability discovery in automotive systems.
Note: This is a testing framework. Only use on vehicles and systems you have explicit authorization to test. Unauthorized vehicle network testing may be illegal and dangerous.
Installation
Prerequisites
- Python 3.7 or higher

Safety and Legal Warnings
- Only test systems you own or have written authorization to test
- Never test on public roads or active vehicles
- Automotive systems control safety-critical functions
- Improper testing can cause vehicle damage or safety hazards
- Always have emergency stop procedures in place
- Consult legal counsel before testing automotive systems
