PCILeech FPGA contains software and HDL code for FPGA based devices that may be used together with the PCILeech Direct Memory Access (DMA) Attack Toolkit. Using FPGA based devices have many advantages over using the USB3380 hardware that have traditionally been supported by PCILeech. FPGA based hardware provides full access to 64-bit memory space without having to rely on a kernel module running on the target system. FPGA based devices are also more stable compared to the USB3380. FPGA based devices may also send raw PCIe Transaction Layer Packets TLPs – allowing for more specialized research.
