Dirt Cheap EMP
Overview
The Dirt Cheap EMP is an XYZ Stage-mountable Electromagnetic Fault Injection tool based on the High Voltage section of the ChipShouter-PicoEMP and FaultyCat.
Unlike other low-cost EMFI tools, the Dirt Cheap EMP features no controller and must be operated by an external fast-gpio capable device, such as a Raspberry Pi RP 2040/2350. An optional RP2040-based controller is also in development.
The EMP device is designed to be XYZ-stage mounted using the same format as a 40mm fan, with 4 4.1mm mounting holes spaced in a square at 32mm from one another. This format allows the device to be mounted on most 3D printer toolheads, as well as on similar easily DIY-made solutions. While traditional commercial and industrial XYZ-stage solutions can cost from hundreds to many thousands of dollars, an adequately comparable level of precision for the purposes of EMFI attacks against consumer-grade hardware can be achieved for a significantly lower cost.
This lowers the barrier to entry for performing more well-automated attacks against chip packages by more hackers. Tactical diffusion, democratization of access.
