S800 Vehicle Network Security Testing

If you're doing automotive security research or pentesting, this gives you a Python framework for CAN bus analysis, ECU fingerprinting, and protocol fuzzing. It handles the typical workflow: capture traffic with a USB-to-CAN adapter, identify ECUs via UDS diagnostics, replay sequences, or run MITM attacks between interfaces. The code examples are solid and show real scenarios like fuzzing specific CAN ID ranges or modifying speed data in transit. You'll need hardware (an OBD-II dongle or similar) and Linux with SocketCAN support. The anomaly detection and custom protocol decoder hooks are nice touches. Obviously only use this on vehicles you own or have written authorization to test, because this is serious stuff that could brick systems or worse.

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.
