IoT & Embedded Device Security Testing

The Internet of Things (IoT) has redefined how devices interact, automate, and operate—from consumer-grade smart gadgets to industrial embedded systems. However, every connection and communication point introduces a potential vulnerability. At BreachZero Cybersecurity Services Pvt Ltd, we perform comprehensive end-to-end security evaluations across IoT ecosystems and embedded devices, ensuring your connected systems are not only smart—but secure.

Our testing framework spans firmware layers, custom hardware interfaces, wireless and wired protocols, cloud integrations, and user interfaces. Whether you’re manufacturing smart meters, building medical IoT devices, or deploying telemetry-driven control systems, our security experts help identify vulnerabilities before adversaries do.

The Unique Challenge of IoT Security

IoT and embedded systems often operate in constrained environments, using custom code, minimal encryption, and proprietary protocols. These systems typically lack robust patching capabilities and are frequently deployed in unmanaged or remote settings, making them prime targets for exploitation.

Our security assessments are engineered to:

  • Uncover hardcoded credentials and insecure firmware design.

  • Test communication protocols for spoofing, replay, and man-in-the-middle attacks.

  • Identify exposed debugging interfaces (UART, JTAG) and insecure APIs.

  • Evaluate privacy implications through telemetry and data transmission audits.

Through white-box, black-box, and gray-box testing methodologies, we simulate real-world attacker techniques to validate device security both at rest and in motion.

 

What We Test – Our Core Capabilities

🔍 Firmware & Binary Analysis

We reverse-engineer firmware images to uncover undocumented functionality, backdoors, insecure default configurations, and weak cryptography.

  • Static and dynamic code analysis

  • Binary fuzzing and exploit research

  • Secure Boot and firmware signature validation

  • Patch management review and update mechanism testing

🔗 Protocol & Communication Stack Testing

Communication protocols act as lifelines between IoT devices and their ecosystems. We rigorously test all layers for weaknesses and data leakage.

  • Wireless protocol analysis (BLE, ZigBee, LoRaWAN, Wi-Fi)

  • MQTT, CoAP, HTTP/HTTPS, and proprietary protocol fuzzing

  • Replay attack and packet injection simulation

  • Encryption scheme validation and key management audits

🔐 Hardware & Interface Security

We probe physical interfaces and microcontrollers to assess protection against tampering, side-channel attacks, and unauthorized access.

  • Debug interface discovery (UART, JTAG, SWD)

  • Secure enclave and TPM review

  • Bus sniffing and chip-off extraction techniques

  • Tamper resistance and casing evaluation

☁️ Cloud & Mobile Ecosystem Security

IoT devices don’t operate in isolation. We review the end-to-end ecosystem—including web portals, companion apps, and cloud APIs—for exploitable flaws.

  • Mobile app API security testing

  • Cloud misconfigurations in IoT dashboards

  • Broken access control and insecure device provisioning

  • TLS/SSL implementation checks and certificate pinning

⚠️ Supply Chain & Third-Party Dependency Assessment

Modern IoT systems often rely on open-source libraries, third-party SDKs, or outsourced firmware development. We evaluate external components for embedded threats.

  • Software Bill of Materials (SBOM) auditing

  • Third-party vulnerability and patch lifecycle review

  • License compliance checks
