/phoenix_technologies_bios/atom.I’m currently trying to analyze a binary protocol between 2 devices, but their communication does not occur over the network, neither can it be sniffed easily.Tizen - An open source, standards-based software platform for multiple device categories.Blog - Möbius Strip Reverse Engineering.IBM Product Security Incident Response Team.* Using flexible software/tools on the Host for receiving/generating/analyzing the TLPs.
* Sending/Receiving TLPs through USB 3.0 (or bufferize it to/from DDR3) * Having a full control of the PCIe core. The PCIe injector is based on a Artix7 FPGA from Xilinx connected to a DDR3 and a high speed USB 3.0 FT601 chip from FTDI. (Using embedded C software to generate/analyze traffic) An other way is to use USB3380 chip, but it is also not flexible enough (only supporting 32bits addressing) and does not allow debugging the PCIe state machine. Most of them were done using a Microblaze inside a Xilinx FPGA to send/receive the TLPs, making it hard to really analyze. Currently, only few attacks were made on PCIe devices. PCIe Injector provides a such tool at a more reasonable price.
Doing security research on PCIe systems can requires very expensive tools (>$50k) and packet generaration for such tools is not a common feature. It is used in all PC (sometime encapsulated in Thunderbolt) and now even in mobile phones. The PCIe bus is now the main high speed communication bus between a processor and its peripherials. with Soon supported by for PCILeech as shown #ccc /oc4kp6KUWd Want to masquerade as a PCIe device? Want to learn DMA attack? Check out the cheapest FPGA based PCIe over USB 3 card with DDR3 RAM.
