Learn practical techniques for bypassing chip and software protection mechanisms through fault injection methods in this comprehensive technical video. Explore real-world examples of how security researchers can manipulate microcontroller behavior by strategically inducing faults, starting with a detailed demonstration of instruction skipping through core voltage manipulation. Discover the essential tools and equipment needed for hardware security testing, understand the fundamental principles behind why and how fault injection attacks work, and examine different categories of fault injection techniques. Master two primary attack vectors: Electromagnetic Fault Injection (EMFI) for remotely inducing faults through electromagnetic pulses, and Voltage Fault Injection (VFI) for manipulating power supply characteristics to cause predictable failures. Gain insights into the hardware security landscape and understand both offensive techniques used by attackers and defensive measures that can be implemented to protect embedded systems from these sophisticated attacks.
