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.

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.

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_<version>_<release>_<date>.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
  • NOTE: Do not extract on top of an existing installation
• Launch Ghidra: ./ghidraRun (ghidraRun.bat for Windows)
  • or launch PyGhidra: ./support/pyGhidraRun (support\pyGhidraRun.bat for Windows)

For additional information and troubleshooting tips about installing and running a Ghidra release, please refer to the Getting Started document which can be found at the root of a Ghidra installation directory.

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

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

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

gradle -I gradle/support/fetchDependencies.gradle

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

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

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

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. Alternatively, Visual Studio Code may be used to edit scripts by clicking the Visual Studio Code icon in the Script Manager. Fully-featured Visual Studio Code projects can be created from a Ghidra CodeBrowser window at Tools -> Create VSCode Module project.

NOTE: Both the GhidraDev plugin for Eclipse and Visual Studio Code integrations only support developing against fully built Ghidra installations which can be downloaded from the Releases page.

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

gradle prepdev eclipse buildNatives

• 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's Guide.
