Ghidra Install
Najee Laboy
When Ghidra is installed, the runnable software gets extracted to a new directory we will referto as . Below is a description of the top-level directories andfiles that can be found in once extraction of the distribution fileis complete.
Ghidra can support multiple users working together on a single project. Individual Ghidra userslaunch and work on their own local copies of a particular Ghidra project but check changes into acommon repository containing all commits to that repository. For detailed information oninstalling/configuring the Ghidra Server see the/server/svrREADME.html file.
Normally, Ghidra is installed as an entire directory structure that allows modular inclusion orremoval of feature sets and also provides many files that can be extended or configured. However,there are times when it would be useful to haveall or some subset of Ghidra compressed into asingle jar file at the expense ofconfiguration options. This makes Ghidra easier to run from thecommand line for headless operation or to use as a library of reverse engineering capabilities foranother Java application.
It is possible to install Ghidra extensions directly into the Ghidra installation directory. This may be required if a system administrator is managing extensions for multiple users that all use a shared installation of Ghidra. It may also be more convenient to manage extensions this way if a Ghidra installation is only ever used headlessly. To install an extension in these cases, simply extract the desired Ghidra extension archive file(s) to the /Ghidra/Extensions directory. For example, on Linux or macOS:
Ghidra supports development in Eclipse by providing a custom Eclipse plugin calledGhidraDev, which can be found in the /Extensions/Eclipsedirectory. For more information on installing and using the GhidraDev Eclipse plugin, see/Extensions/Eclipse/GhidraDev/GhidraDev_README.html.
When launching Ghidra with the provided scripts in and/support, you may encounter the following error messages:
- Problem: Java runtime not found.
- Solution: A Java runtime (java/java.exe) is required to be on the system PATH. Please see the Requirements section for what version of Java must be pre-installed for Ghidra to launch.
Solution: The Ghidra launch script uses the Java runtime on the system PATH to find a supported version of a Java Development Kit (JDK) that Ghidra needs to complete its launch. Please see the Requirements section for what version of JDK must be pre-installed for Ghidra to launch.
Solution: Ghidra failed to launch in the background and the error message describing the cause of the failure is being suppressed. Rerun Ghidra in the foreground by setting the LAUNCH_MODE variable in the launch script you ran to fg. Alternatively, you can use the /support/ghidraDebug script to run Ghidra in debug mode, which will also allow you to see the error message as well as additional debug output. NOTE: By default, running Ghidra in debug mode listens on 127.0.0.1:18001.
You can either manually install JDK 11 by downloading the tarball or install it through the package manager of your Linux distro. Ideally, installing via package managers is the way to go since it's much quicker and hassle-free than the former hands-on method.
Ghidra SRE isn't typically installed into a system, and there isn't a traditional installer included with the Ghidra release file. You just have to download the binaries, make them executable using the chmod command, and run them from the terminal on the go.
Among the extracted files, you will find a file named ghidraRun. It is a Bash script to launch Ghidra. Pop up a shell in the directory, make the file executable using the chmod command, and run it from the command line using the following commands:
The current way to install the plugin is to go to the file->Install Extension in the project window, and add my plugin there. However, in my scenario, I don't have an access to the GUI and I want to deploy Ghidra for Headless Analysis.
This dialog is part of the method ghidra.framework.project.tool.GhidraTool#checkForNewExtensions and the actual install process happens ghidra.framework.project.tool.GhidraTool#addInstalledExtensions.
In the previous section, we generated the project for the GhidraDev Eclipse plugin. Next, we need to import the GhidraDev project into Eclipse and build it. Before we do that, however, we need to install the following Eclipse plugins:
We can now import the GhidraDev plugin into Eclipse with the plugins installed. Once the plugin is imported, we will export it and install it in Eclipse, allowing us to launch Ghidra from Eclipse and debug our various plugins and scripts.
From this window, select the ghidra.ghiradev feature in the checkbox and specify a location for the archive to be exported; in the window shown below, I have set that to /home/dev/ghidraDev.zip. Please note this location because, in the next section, we will be importing this archive into Eclipse!
Next, we need to link our current Ghidra installation; if you followed the previous steps and built Ghidra in the docker container, this will be our ghidra_10.2_DEV directory that we extracted earlier.
To add a new Java file to our project, download the MakeFunctionsScriptGBA.java file and copy it into the project location. In my case, this is in the /ghidra_scripts directory. If you do not have that directory, you can determine the location by right-clicking on the Home Scripts folder in the project directory and clicking Properties causing the following window to appear:
This will cause the previously linked Ghidra installation to launch. Once it launches, we will select our target binary and then open up the Script Manager window by clicking Window > Script Manager displaying the following:
You will also need the Xcode Command Line Tools installed. (These are already installed if you have Homebrew.) Run the clang command in Terminal, and macOS will prompt you to install the command line tools.
Ghidrathon replaces the existing Python 2 extension implemented via Jython. This includes the interactive interpreter window, integration with the Ghidra Script Manager, and script execution in Ghidra headless mode. You can build and install Ghidrathon using the steps outlined in our README to start using the features described below.
We can start using Unicorn in Ghidra by installing the Unicorn module for the same local Python installation that we used to build Ghidrathon. Once installed, we can import and use the Unicorn module just as we would in any standard Python setup. In our example here we want to read the stack string code from our Ghidra database, emulate it using Unicorn, and print the resulting stack string to our Ghidrathon interpreter Window.
For this example, you will need to install the binwalk tool and ensure that it is in your $path. For Ubuntu, use apt-get install binwalk; for Mac users either sudo port install binwalk (for MacPorts) or brew install binwalk (for Homebrew); Windows users should follow this link for further instructions.
Ghidra is a self contained installation that you just need to unpack. It does not need to be compiled and will run from any location as long as java is in your path. Installing Ghidra is as easy as downloading it and unzipping it in your home directory. Download it from -sre.org/
This short post will walk through the steps required to automate Ghidra installation. This is useful when setting up Ghidra for multiple minimal Linux/Ubuntu installations to do quick Malware analysis.
Next, we'll need to install unzip, as we'll be downloading a Ghidra zip file from GitHub later. The -y option is added so it will select y when y/n is prompted. This will make the automation smoother, as it will not require user input.
The script in the previous section will completely automate the installation and will not prompt the user to double check the Ghidra ZIP file hash. If we want to double check the ZIP file hash before unzipping and running Ghidra, we will use sha256sum on ghidra_10.1.5_PUBLIC_20220726.zip, output the result, and ask the user before moving on.
Pyhidra was initially developed for use with Dragodis and is designed to be installable without requiring Java or Ghidra. Due to this restriction, the Java plugin for Pyhidra is compiled and installed automatically during first use. The Java plugin is managed by Pyhidra and will automatically be rebuilt as necessary.
The PyhidraLauncher can also be configured through the use of a registered entry point on your own python project.This is useful for installing your own Ghidra plugin which uses pyhidra and self-compiles.
Ghidra must be started via pyhidraw and the plugin must be enabled for the user interface features to be present. Once these prerequisites are met the pyhidra menu item will be available in the Window toolbar menu and all Python scripts outside of the Ghidra installation will automatically be run with CPython. Any Python script found within the Ghidra installation will be run using Jython to prevent causing issues with any analyzers or Ghidra internals that use them. Below is a screenshot of the standard Python interpreter in Ghidra which is using CPython instead of Jython. It will appear when pyhidra is opened from the Window toolbar menu.
This is a quick guide to get you started on installing FlareVM by FireEye and setting up Ghidra for reverse engineering malware. The FlareVM installation is a script you can run that will turn a Windows 10 installation into a reverse engineering environment that has all the tools needed for binary analysis, RE, and a safe place to detonate malicious software.
The FlareVM script attempts to take some steps to prepare the Windows 10 installation to turn off AV services that will interfere with what the VM is being built out for. However, I have experienced many issues with this failing to work properly and have found taking the following steps manually to make everything work properly.
