Automotive Penetration Testing
Modern vehicles integrate software, communication systems, and sensors making them an attractive target for attackers.
Automotive penetration testing evaluates the security of vehicle components, control units, communication protocols, and connectivity interfaces just as a real attacker would.
The assessment is designed to identify vulnerabilities, misconfigurations, and security gaps that could enable unauthorized control, safety risks, operational disruption or data leakage.
Uncover Critical Vulnerabilities in Vehicle Systems Before They Become a Risk
In the automotive world, even a small vulnerability can turn into a major issue—from data leakage to disruption of critical systems.
Internal communication interfaces (CAN/LIN), control units, gateways, cellular connectivity, Wi-Fi, Bluetooth, and OTA processes—all represent potential attack surfaces.
At RedEntry, we perform automotive penetration testing based on leading standards and methodologies such as ISO/SAE 21434, UNECE, OWASP, and MITRE, fully tailored to the vehicle architecture, components, and relevant threat scenarios.
Our testing combines specialized automotive tools with deep manual research to uncover complex and advanced vulnerabilities.
Critical Vulnerabilities We Can Identify
- Message Injection / Replay attacks on CAN/LIN
- Gateway vulnerabilities and network segmentation bypass
- Bypassing authentication and authorization in ECUs (Access Control)
- Exposure in OBD-II and Diagnostics interfaces (UDS / DoIP)
- Weaknesses in OTA processes—signing, update validation, and supply chain
- Attacks on Telematics / TCU and Backend-Vehicle interfaces
- Vulnerabilities in Bluetooth / Wi-Fi / Cellular enabling remote access
- Leakage of user/vehicle data (PII, location, telemetry)
- Weaknesses in companion apps and connected APIs
- Poor encryption key management and exposed secrets

Types of Automotive Penetration Testing
01
ECU-Level Penetration Testing
Penetration testing at the Electronic Control Unit (ECU) level, examining both hardware and software security.
The testing focuses on communication interfaces, diagnostic services, authentication mechanisms, and authorization controls.
Its goal is to identify vulnerabilities that allow unauthorized access, parameter manipulation, or bypassing security mechanisms.
Aligned with OEM requirements and mandatory automotive regulations.
02
Vehicle-Level Penetration Testing
A comprehensive test at the full vehicle level, examining the E/E architecture and domain separation.
The assessment identifies cross-system attack scenarios, lateral movement, and segmentation bypass within in-vehicle networks.
Focus is placed on safety-critical components and the potential impact on vehicle functionality.
Supports compliance with UNECE R155 and Type Approval requirements.
03
Fuzz Testing–Automotive Protocols
Dedicated fuzz testing for in-vehicle protocols, interfaces and communications.
The test injects abnormal and random inputs to uncover crashes, logical anomalies and zero-day vulnerabilities.
Adapted for ECUs, vehicle networks, diagnostics, and communication interfaces.
Enables scalable and efficient testing as part of security and regulatory processes.
04
Mobile, API & Cloud Penetration Testing
Penetration testing for mobile applications, APIs and cloud environments connected to the vehicle (Connected Car).
Includes driver apps, backend systems, API interfaces and vehicle-to-cloud communication.
Aims to identify authorization flaws, session management issues, data exposure and end-to-end attack paths.
Critical for protecting user data, remote control capabilities and OTA processes.
Tools We Use
Preparation & Scoping
Kickoff meeting to understand the product, hardware/software components and use cases.
