PicoEMP – A Raspberry Pi Pico-based open-source electromagnetic fault injector designed for EMFI testing and research

ChipSHOUTER PicoEMP

The PicoEMP is a compact, low-cost, open-source electromagnetic fault injector (EMFI) tool developed by Colin O’Flynn for researchers, hobbyists, and educators interested in hardware security. Unlike NewAE’s professional-grade ChipSHOUTER, PicoEMP is a bare-bones device designed to be safe, usable, and most importantly, affordable. Built around the Raspberry Pi Pico, this device generates high-voltage pulses using a transformer circuit (originally for photographic flash charging) to discharge energy from a low-ESR ceramic capacitor into a custom-made coil tip, which creates an electromagnetic field capable of injecting a little bit of power to the internals of the processors such as registers and SRAM. This can be exploited to flip bits and test the robustness of embedded systems against such attacks. ChipSHOUTER-PicoEMP specifications Main controller – Raspberry Pi Pico (RP2040 dual-core Arm Cortex-M0+ MCU @ up to 133 MHz) Purpose – Electromagnetic Fault Injection (EMFI) for testing embedded systems security Components High-voltage pulse generator circuit […]
