MEAnalyzer - Intel Engine Firmware Analysis Tool

•    Python

ME Analyzer is a tool which parses Intel Engine & PMC firmware images from the (Converged Security) Management Engine, (Converged Security) Trusted Execution Engine, (Converged Security) Server Platform Services & Power Management Controller families. It can be used by end-users who are looking for all relevant firmware information such as Family, Version, Release, Type, Date, SKU, Platform etc. It is capable of detecting new/unknown firmware, checking firmware health, Updated/Outdated status and many more. ME Analyzer is also a powerful Engine firmware research analysis tool with multiple structures which allow, among others, full parsing and unpacking of Converged Security Engine (CSE) code & file system, Flash Partition Table (FPT), Boot Partition Descriptor Table (BPDT/IFWI), CSE Layout Table (LT), advanced Size detection etc. Moreover, with the help of its extensive database, ME Analyzer is capable of uniquely categorizing all supported Engine firmware as well as check for any firmware which have not been stored at the Intel Engine Firmware Repositories yet. ME Analyzer allows end-users and/or researchers to quickly analyze and/or report new firmware versions without the use of special Intel tools (FIT/FITC, FWUpdate) or Hex Editors. To do that effectively, a database had to be built. The Intel Engine Firmware Repositories is a collection of every (CS)ME, (CS)TXE & (CS)SPS firmware we have found. Its existence is very important for ME Analyzer as it allows us to continue doing research, find new types of firmware, compare same major version releases for similarities, check for updated firmware etc. Bundled with ME Analyzer is a file called MEA.dat which is required for the program to run. It includes entries for all Engine firmware that are available to us. This accommodates primarily three actions: a) Detect each firmware's Family via unique identifier keys, b) Check whether the imported firmware is up to date and c) Help find new Engine firmware sooner by reporting them at the Intel Management Engine: Drivers, Firmware & System Tools or Intel Trusted Execution Engine: Drivers, Firmware & System Tools threads respectively.
