Package: psptool
PSPToolPSPTool is a Swiss Army knife for dealing with firmware of theAMD Secure Processor (ASP), formerly known asPlatform Security ProcessororPSP. It can parse, extract, and replace AMD firmware insideUEFI imagesas part of BIOS updates targetingAMD platforms.It is based on reverse-engineering efforts of AMD'sproprietary filesystemused topack firmware blobsintoUEFI Firmware Images. These are usually 16MB (or 8MB, or 32MB) in size and can be conveniently parsed byUEFITool. However, all binary blobs by AMD are located in padding volumes unparsable by UEFITool.PSPTool favourably works with UEFI images as obtained through BIOS updates. If these updates are only available through Windows executables, tools likeinnoextractcan help.PSPTool was developed at TU Berlin in context of the following research:2023, talk:Jailbreaking an Electric Vehicle in 2023 or What It Means to Hotwire Tesla's x86-Based Seat Heater2023, paper:faulTPM: Exposing AMD fTPMs' Deepest Secrets2021, paper:One Glitch to Rule Them All: Fault Injection Attacks Against AMD's Secure Encrypted Virtualization2020, talk:All You Ever Wanted to Know about the AMD Platform Security Processor and were Afraid to Emulate2019, talk:Uncover, Understand, Own - Regaining Control Over Your AMD CPU2019, paper:Insecure Until Proven Updated: Analyzing AMD SEV's Remote Attestation2019, talk:Dissecting the AMD Platform Security ProcessorInstallationYou can either install PSPTool's latest release fromPyPI,pip3 install psptoolor install it freshly offGitHub:git clone https://github.com/PSPReverse/PSPTool
cd PSPTool
pip3 install .If you intend to make changes to the code and would like your installation to point to the latest changes, install iteditable:pip3 install -e .Please note that the integration tests require ROM files from a private submodule (tests/integration/fixtures). If you would like to get access to these, contact us.CLI UsagePSPTool offers a range of features from thecommand line.Example 1:List all firmware entries of a given BIOS ROM.$ psptool Lenovo_Thinkpad_T495_r12uj35wd.isoClick to expand output+-----+----------+-----------+----------+--------------------------------+
