What is IoT & Hardware Hacking? This field involves identifying and exploiting vulnerabilities in connected devices (Internet of Things) and their underlying hardware components to understand risks and improve security.
Core Topics
- IoT Architectures & Protocols: Understanding typical IoT system designs and communication protocols (MQTT, CoAP, Zigbee, BLE, etc.).
- Common Vulnerabilities: Weak/default credentials, insecure network services, lack of encryption, insecure firmware updates, hardware interface vulnerabilities (UART, JTAG).
- Reverse Engineering: Analyzing firmware binaries and physical hardware components to understand functionality and find weaknesses.
- Security Best Practices: Principles for designing and deploying secure IoT devices (secure boot, firmware signing, secure communication, etc.).
Key hardware and software tools used for analyzing and interacting with IoT devices.
Hardware Analysis & Interfacing
Bus Pirate
A universal bus interface tool that talks to most chips from a PC serial terminal, useful for debugging and probing hardware.
JTAGulator
An open source hardware tool that assists in identifying JTAG connections from test points, vias, or component pads on a target device.
Logic Analyzers
Instruments that capture and display signals from a digital system or circuit. Essential for debugging embedded communications (e.g., Saleae, DSLogic, using Sigrok).
Firmware & Reverse Engineering
Binwalk
