# Ghidra Software Reverse Engineering Framework
Ghidra is a software reverse engineering (SRE) framework created and maintained by the
[National Security Agency][nsa] 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

## Security Warning
**WARNING:** There are known security vulnerabilities within certain versions of Ghidra. Before
proceeding, please read through Ghidra's [Security Advisories][security] 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][jdk]
* Download a Ghidra [release file][releases]
- **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
* 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][jdk]
* [Gradle 8.5+][gradle] (or provided Gradle wrapper if Internet connection is available)
* [Python3][python3] (version 3.9 to 3.12) with bundled pip
* make, gcc, and g++ (Linux/macOS-only)
* [Microsoft Visual Studio][vs] 2017+ or [Microsoft C++ Build Tools][vcbuildtools] with the
following components installed (Windows-only):
- MSVC
- Windows SDK
- C++ ATL
##### Download and extract the source:
[Download from GitHub][master]
```
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][devguide].
For issues building, please check the [Known Issues][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][ghidradev].
**NOTE:** The *GhidraDev* plugin for Eclipse only supports developing against fully built
Ghidra installations which can be downloaded from the [Releases][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](#build) so the build completes without errors
* Install [Eclipse IDE for Java Developers][eclipse]
##### 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][devguide].
