Cyber Security Testing
Penetration Testing for Hardware Devices
Identify vulnerabilities in connected devices before attackers can exploit them. IoT penetration testing fortifies your systems and protects your business.
What Is Hardware Penetration Testing?
Hardware and IoT Penetration Testing is a focused security evaluation aimed at simulating real-world attacks on connected devices, embedded systems, and their supporting infrastructure. The goal is to detect vulnerabilities before they can be exploited in the field.
This testing process mimics the tactics employed by attackers to uncover weaknesses such as insecure firmware, exposed debug interfaces, unencrypted communication, inadequate authentication, and insecure cloud integrations—all of which can result in device compromise or network breaches.
Common Security Risks in Hardware Devices
Unencrypted or Tampered Device Communication
Hardware IoT devices frequently transmit data via Wi-Fi, Bluetooth, or proprietary protocols. If this communication is not adequately encrypted or validated, attackers can intercept, manipulate, or replay data, potentially leading to unauthorised control or data leakage.
What We Test For:
- Unencrypted data transmission
- Insecure use of Bluetooth or Zigbee
- Lack of certificate validation
- Replay and MitM attack vectors
- Weak encryption protocols
Unprotected Physical or Software Access Points
Many devices ship with active debug ports like UART, JTAG, or SWD for development. If left exposed, these interfaces can allow attackers to bypass authentication, dump firmware, or gain root access.
What We Test For:
- Accessible UART/JTAG interfaces
- Debug mode is enabled in production
- Lack of tamper resistance
- Firmware extraction methods
- Bypass of bootloader protections
Unprotected or Unvalidated System Software
Firmware and bootloaders are foundational to IoT security. If not properly secured, attackers can modify system behaviour, inject malware, or downgrade devices to known-vulnerable states.
What We Test For:
- Lack of firmware signature verification
- Firmware downgrade vulnerabilities
- Insecure over-the-air (OTA) update
- mechanisms
- Hardcoded credentials or keys
- Absence of secure boot processes
Inadequate Access Controls on Device Functions
Hardware (IoT) devices often rely on weak or poorly implemented authentication, allowing attackers to access sensitive functions or impersonate legitimate users.
What We Test For:
- Default or hardcoded credentials
- Weak password policies
- Lack of role-based access controls
- Unprotected admin panels or APIs
- Bypass of local authentication
