Security validation

Automotive Penetration Testing and Red Team Assessment

Validate how a vehicle system behaves under realistic attack conditions, then convert findings into prioritised, reproducible engineering actions.

Core deliverables
  • Test plan and agreed scope
  • Reproducible finding records with severity
  • Attack path documentation
  • Remediation guidance

The problem we are asked to solve

  • Security controls are specified but never tested against a capable attacker.
  • Findings arrive as tool output rather than engineering-ready evidence.
  • Testing covers a single ECU while the real attack path crosses domains.
  • Retesting after remediation is unstructured or skipped.

What changes as a result

  • Reproducible evidence of exploitable weaknesses
  • Attack paths traced across interfaces and supply-chain boundaries
  • Severity-rated findings with concrete remediation guidance
  • Verification evidence usable in release and approval decisions

Scope of work

What the engagement covers

Scope is agreed per programme. These are the activities we most often deliver for this service.

  • ECU and embedded hardware testing
  • CAN, LIN, and automotive Ethernet assessment
  • Wireless interface testing including Bluetooth and Wi-Fi
  • Telematics and connectivity testing
  • Firmware and bootloader analysis
  • Fuzzing and fault injection
  • Mobile application and API testing
  • Backend and cloud interface testing
  • Red team scenario design
  • Structured retesting

Engagement methodology

How we work

A predictable sequence, adapted to your process and release gates rather than replacing them.

  1. 01

    Scope and rules of engagement

    Agree targets, access, test environment, safety constraints, and reporting expectations in writing.

  2. 02

    Reconnaissance and modelling

    Map interfaces, services, and trust boundaries on the actual target to build a realistic attack model.

  3. 03

    Execute testing

    Work through the attack model with manual testing, fuzzing, and fault injection, recording reproduction steps.

  4. 04

    Report with evidence

    Deliver severity-rated findings with reproduction detail and remediation guidance an engineer can act on.

  5. 05

    Retest

    Confirm fixes resolve the original finding without introducing new exposure on the affected interface.

Deliverables

Every engagement ends with artefacts your organisation owns and can defend in review.

  • Test plan and agreed scope
  • Reproducible finding records with severity
  • Attack path documentation
  • Remediation guidance
  • Retest report
  • Management summary for programme stakeholders

Relevant standards

We help organisations interpret and implement these requirements. We do not certify or approve organisations.

  • ISO/SAE 21434
  • UNECE R155

Typical use cases

  • ECU security validation before a release gate
  • Vehicle attack-surface assessment
  • Telematics and connected-service testing
  • Supplier component security review

Evidence

Case studies covering Penetration Testing and Red Teaming work are being prepared for publication. Automotive security engagements are normally confidential, so we discuss comparable scope, method, and deliverables directly rather than publishing unverifiable claims.

Questions

Frequently asked

What do you need to start a penetration test?
Typically a defined scope, target samples or bench access, interface documentation, and agreed rules of engagement. We can help define scope where documentation is incomplete.
Do you provide retesting after fixes?
Yes. Retesting confirms that remediation resolves the original finding and does not introduce new exposure on the affected interface.
