Ghidra Software Reverse Engineering Framework

Ghidra is a software reverse engineering (SRE) framework created and maintained by the
National Security Agency Research Directorate. This framework includes a suite of
full-featured, high-end software analysis tools that enable users to analyze compiled code on a
variety of platforms including Windows, macOS, and Linux. Capabilities include disassembly,
assembly, decompilation, graphing, and scripting, along with hundreds of other features. Ghidra
supports a wide variety of processor instruction sets and executable formats and can be run in both
user-interactive and automated modes. Users may also develop their own Ghidra extension components
and/or scripts using Java or Python.

In support of NSA's Cybersecurity mission, Ghidra was built to solve scaling and teaming problems
on complex SRE efforts, and to provide a customizable and extensible SRE research platform. NSA has
applied Ghidra SRE capabilities to a variety of problems that involve analyzing malicious code and
generating deep insights for SRE analysts who seek a better understanding of potential
vulnerabilities in networks and systems.

If you are a U.S. citizen interested in projects like this, to develop Ghidra and other
cybersecurity tools for NSA to help protect our nation and its allies, consider applying for a
career with us.

Security Warning

WARNING: There are known security vulnerabilities within certain versions of Ghidra. Before
proceeding, please read through Ghidra's Security Advisories for a better understanding
of how you might be impacted.

Install

To install an official pre-built multi-platform Ghidra release:

• Install JDK 21 64-bit
• Download a Ghidra release file
  • NOTE: The official multi-platform release file is named
    ghidra___.zip which can be found under the "Assets" drop-down.
    Downloading either of the files named "Source Code" is not correct for this step.
• Extract the Ghidra release file
• Launch Ghidra: ./ghidraRun (or ghidraRun.bat for Windows)

For additional information and troubleshooting tips about installing and running a Ghidra release,
please refer to docs/InstallationGuide.html which can be found in your extracted Ghidra release
directory.

Build

To create the latest development build for your platform from this source repository:

Install build tools:

• JDK 21 64-bit
• Gradle 8.5+ (or provided Gradle wrapper if Internet connection is available)
• Python3 (version 3.9 to 3.12) with bundled pip
• make, gcc, and g++ (Linux/macOS-only)
• Microsoft Visual Studio 2017+ or Microsoft C++ Build Tools with the
  following components installed (Windows-only):
  • MSVC
  • Windows SDK
  • C++ ATL

Download and extract the source:

Download from GitHub

unzip ghidra-master
cd ghidra-master

NOTE: Instead of downloading the compressed source, you may instead want to clone the GitHub
repository: git clone https://github.com/NationalSecurityAgency/ghidra.git

Download additional build dependencies into source repository:

NOTE: If an Internet connection is available and you did not install Gradle, the following
gradle commands may be replaced with ./gradle(.bat).

gradle -I gradle/support/fetchDependencies.gradle

Create development build:

gradle buildGhidra

The compressed development build will be located at build/dist/.

For more detailed information on building Ghidra, please read the Developer Guide.

For issues building, please check the Known Issues section for possible solutions.

Develop

User Scripts and Extensions

Ghidra installations support users writing custom scripts and extensions via the GhidraDev plugin
for Eclipse. The plugin and its corresponding instructions can be found within a Ghidra release at
Extensions/Eclipse/GhidraDev/ or at this link.

NOTE: The GhidraDev plugin for Eclipse only supports developing against fully built
Ghidra installations which can be downloaded from the Releases page.

Advanced Development

To develop the Ghidra tool itself, it is highly recommended to use Eclipse, which the Ghidra
development process has been highly customized for.

Install build and development tools:

• Follow the above build instructions so the build completes without errors
• Install Eclipse IDE for Java Developers

Prepare the development environment:

gradle prepdev eclipse buildNatives

Import Ghidra projects into Eclipse:

• File -> Import...
• General | Existing Projects into Workspace
• Select root directory to be your downloaded or cloned ghidra source repository
• Check Search for nested projects
• Click Finish

When Eclipse finishes building the projects, Ghidra can be launched and debugged with the provided
Ghidra Eclipse run configuration.

For more detailed information on developing Ghidra, please read the Developer Guide.
