IoT and Embedded Device Penetration Testing

Secure your connected devices before attackers exploit them.

Overview

The Internet of Things (IoT) refers to all the connected devices in your business, from industrial sensors monitoring operations to smart equipment like electric vehicle (EV) charging stations. These devices often work quietly in the background but are critical to your daily operations. Many organizations don’t realize they have IoT devices or the unique security risks they bring.

IoT devices often suffer from weak passwords, outdated software, and unsecured communication channels, making them easy targets for attackers. For example, if an EV charger is insecure, attackers could disrupt charging services, manipulate billing, or even charge vehicles for free, leading to direct financial losses. Compromised IoT devices can also become entry points into your broader network, risking data breaches or operational failure.

Our IoT and Embedded Device Penetration Testing service uncovers vulnerabilities across hardware, firmware, network protocols, and cloud integrations to help you secure your entire IoT ecosystem before attackers exploit these gaps.

IoT

Device Discovery

Inventory devices, firmware versions, and communication channels.

Hardware Analysis

Assess physical interfaces, debug ports, and tampering resistance.

Firmware Review

Extract and analyze firmware for backdoors or insecure configurations.

Network Protocol Testing

Evaluate MQTT, CoAP, Modbus, and proprietary communication stacks.

Authentication & Access Control

Test default credentials, weak keys, and insecure access mechanisms.

EV Charging Station Checks

Validate OCPP protocol, backend communication, and payment security.

Cloud & API Integration

Assess cloud services and APIs interacting with IoT devices.

Exploitation Simulation

Demonstrate device takeover, data interception, and code execution risks.

Testing Methodology

1

Scoping & Kick-off

Define objectives, in-scope assets, exclusions, testing mode (blackbox or greybox), credentials, test windows, and approvals.

2

Reconnaissance

Map hardware components, firmware, interfaces, protocols, mobile apps, and cloud services to understand the attack surface.

3

Scanning & Vulnerability Identification

Combine automated firmware analysis with manual testing of authentication, encryption, APIs, and trust boundaries across device, application, and cloud layers.

4

Exploitation

Safely validate vulnerabilities with proof-of-concepts demonstrating device compromise, data extraction, or network access without disrupting production systems.

5

Reporting & Debrief

Produce a comprehensive report including executive summary, scope, methodology, prioritized findings with PoCs, business impact, risk ratings, and actionable remediation, and present results during a restitution meeting.

6

Retest (Optional)

Ensure all identified vulnerabilities have been properly fixed without introducing new risks.

FAQ

Frequently Asked Questions

  • Physical access to target IoT devices (if required).
  • Network credentials or wireless access keys for IoT networks.
  • Device documentation including default credentials and configuration guides.

Connected devices expand your attack surface, creating more opportunities for vulnerabilities that can cause operational disruptions, data breaches, or even physical malfunctions. These issues are especially critical in EV charging infrastructure, where exploitation could affect public charging or enable unauthorized free charging.

Typically between 5 and 10 business days, depending on device variety, complexity, and integration scope.

All tests are safe and non-destructive. When testing in production, activities are coordinated to minimize impact. Any potentially disruptive actions are performed only after agreement.
