Testing Areas

What We Test in Your Connected Vehicle

Comprehensive security coverage spanning ECUs, in-vehicle networks, connectivity, and regulatory compliance.

ECU Firmware Analysis

Reverse-engineer ECU firmware for hardcoded secrets, insecure boot loaders, and vulnerable libraries including AUTOSAR SecOC implementation gaps.

Secure On-Board Communication

Test SecOC implementations for cryptographic weaknesses, key management flaws, and message authentication bypass vulnerabilities.

Boot Chain Security

Verify secure boot implementation across ECUs, assess firmware signing validation, and evaluate anti-rollback protection mechanisms.

AUTOSAR Security

Review AUTOSAR software component configurations for security policy violations, access control gaps, and inter-ECU communication weaknesses.

Memory and Storage

Evaluate ECU flash storage for unencrypted sensitive data, accessible debug interfaces, and recoverable cryptographic material.

Diagnostic Interface

Test UDS diagnostic sessions, OBD-II gateway configurations, and diagnostic access control for unauthorised ECU reprogramming paths.

CAN and CAN-FD Testing

Assess CAN bus for message injection, spoofing, denial-of-service, and unauthorised diagnostic access via OBD-II and UDS protocols.

Automotive Ethernet

Test Ethernet-based in-vehicle networks for VLAN hopping, ARP spoofing, and IP-based attacks against high-bandwidth controller domains.

LIN and FlexRay

Evaluate LIN bus for message injection and FlexRay for timing manipulation vulnerabilities in safety-critical subsystems.

Gateway and Firewall

Assess central gateway modules and in-vehicle firewalls for routing misconfigurations, bypass opportunities, and insufficient traffic isolation.

Message Injection and DoS

Test for unauthorised CAN message injection, bus flooding, and denial-of-service attacks that can affect vehicle safety systems.

Network Forensics

Analyse in-vehicle network traffic patterns, identify anomalous message sequences, and map communication relationships between ECUs.

V2X Communication

Test V2V, V2I, and V2G for message manipulation, Sybil attacks, and PKI certificate management weaknesses in C-ITS and DSRC stacks.

OTA Update Security

Evaluate OTA update mechanisms for firmware integrity, rollback protection, code signing validation, and UNECE R156 SUMS compliance.

Bluetooth and Wi-Fi

Assess Bluetooth and Wi-Fi connectivity for pairing bypass, unauthorised access, and man-in-the-middle attacks against infotainment systems.

Companion App and Backend

Test mobile companion apps, telematics platforms, and cloud backends for authentication bypass and unauthorised vehicle control.

Cellular and Telematics

Evaluate cellular communication, telematics units, and remote services for interception, spoofing, and unauthorised remote vehicle access.

UNECE R155/R156

Validate your CSMS and SUMS against UNECE WP.29 requirements mandatory for vehicle type approval across 54 contracting parties.

Methodology

How We Run an Automotive Security Assessment

A structured six-phase process aligned with ISO/SAE 21434 and UNECE WP.29, from attack surface mapping through compliance validation.

Phase 01

Attack Surface Mapping

Identify all vehicle interfaces using ISO/SAE 21434 TARA. Map ECU communication, external connectivity, and diagnostic access paths.

Phase 02

ECU and Firmware Analysis

Extract and reverse-engineer ECU firmware for hardcoded credentials, insecure boot chains, and SecOC implementation gaps.

Phase 03

In-Vehicle Network Testing

Test CAN, CAN-FD, LIN, and automotive Ethernet for message injection, spoofing, and DoS including UDS diagnostic session exploitation.

Phase 04

Connectivity and V2X Testing

Assess V2X communication, telematics, Bluetooth, and Wi-Fi for MITM attacks, certificate misuse, and unauthorised remote vehicle access paths.

Phase 05

OTA and Backend Validation

Review OTA update integrity, code signing, rollback protection, and cloud backend authentication for UNECE R156 SUMS compliance.

Phase 06

Reporting and Compliance Roadmap

Deliver prioritised findings with ISO/SAE 21434 damage ratings, UNECE R155/R156 gap analysis, and a phased remediation roadmap.

Who It's For

Built for the Connected Vehicle Ecosystem

OEMs and Vehicle Manufacturers

Automotive original equipment manufacturers needing to validate connected vehicle security and achieve UNECE WP.29 type approval.

Tier-1 and Tier-2 Suppliers

Component suppliers providing ECUs, telematics units, and connectivity modules that must demonstrate security compliance to OEMs.

Mobility and Fleet Operators

Connected fleet operators and mobility service providers whose vehicles are continuously exposed to remote attack surfaces.

FAQ

Questions We Get Asked Often

Automotive security assessment is a purpose-built evaluation of connected vehicles covering ECUs, in-vehicle networks, V2X communication, and OTA update mechanisms. It protects drivers, passengers, and road infrastructure from critical cyber-physical threats, aligned with ISO/SAE 21434 and UNECE WP.29.

UNECE WP.29 R155 requires a Cyber Security Management System (CSMS) and R156 requires a Software Update Management System (SUMS). Both are mandatory for vehicle type approval in 54 contracting parties. Scyverge validates your compliance against these requirements.

Yes. We test CAN, CAN-FD, LIN, and automotive Ethernet for message injection, spoofing, denial-of-service, and unauthorised diagnostic access. Testing includes UDS session exploitation and OBD-II gateway bypass assessment.

No. All testing is conducted in controlled lab environments or on bench setups, never on public roads. We follow strict safety protocols and coordinate with your engineering team to ensure testing never compromises vehicle safety systems.

Scyverge aligns assessments with ISO/SAE 21434, UNECE WP.29 R155/R156, ISO/SAE 21434, and AUTOSAR security specifications. Findings are mapped to these frameworks for type approval and regulatory compliance.
