Welcome to the world of BinDiff! This powerful open-source tool enables researchers and engineers to compare binary files effectively, unveiling the differences and similarities in disassembled code. In this blog post, we will guide you through the steps to get started with BinDiff, along with troubleshooting tips to enhance your experience.

About BinDiff

BinDiff excels at assisting vulnerability researchers and engineers in identifying changes between binary files across various architectures like x86, MIPS, ARM, and PowerPC. Its functionality allows users to detect changes in code, which is crucial for securing applications and systems. Here are a few notable use cases:

• Compare binary files for different architectures supported by popular disassemblers.
• Identify identical or similar functions in disparate binaries.
• Port function names, comments, and local names across various disassemblies.
• Highlight changes within the same function between multiple binary versions.

Quickstart

Ready to dive in? First, download the prebuilt installation packages from the releases page. Please note that BinDiff relies on a disassembler, and it supports IDA Pro, Binary Ninja, and Ghidra out of the box.

Documentation

For more information, a subset of the existing manual is available, alongside useful details found in the docs directory.

Understanding BinDiff’s Structure: Analogy Time!

To grasp the functionality of BinDiff, think of it as a detective agency comparing two different versions of a suspect’s profile (the binary files). Each detective (BinDiff’s components) specializes in a particular task:

• CMake: The logistics officer that prepares everything for operation.
• Fixtures: The evidence repository, containing all necessary files to test findings.
• IDA Integration: The liaison with the primary investigator (IDA Pro), ensuring effective collaboration.
• Java Source Code: The tech-savvy partner that creates a visual representation of all findings.
• Matching Algorithms: The analysts who process information and spot significant differences.
• Packaging Tools: The final report makers, packaging the results for easy access.

This team works cohesively to uncover the intricacies hidden within binary files, delivering insights that aid in security research.

Building from Source

If you plan to build BinDiff from source, follow these steps:

• Ensure you have the required dependencies, such as BinExport, Boost, CMake, Ninja, and the suitable compiler based on your OS.
• Clone BinExport and configure build files using CMake. For Linux, you can run:

mkdir -p buildout
    git clone https://github.com/google/binexport build/binexport
    unzip -q path/to/idasdk_pro80.zip -d build/idasdk
    cmake -S . -B buildout -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=buildout -DBINDIFF_BINEXPORT_DIR=build/binexport -DIdaSdk_ROOT_DIR=$PWD/build/idasdk

• Finally, invoke the build command and install it using:

cmake --build buildout --config Release
    cmake --install buildout --config Release

Troubleshooting

While using BinDiff, you may encounter some obstacles. Here are a few troubleshooting tips:

• Make sure all dependencies are properly installed, especially Boost, CMake, and the required compilers.
• If the binary is not building correctly, check the output for missing dependencies.
• In case of performance issues, ensure you are using the appropriate versions as outlined in the documentation.
