Ghidra extension that uses BinDiff on your Ghidra project to find matching functions and rename them automatically (BinDiff 6 supported). Check out the BinDiff manual to see how it works and how it matches functions / basic blocks. However, with this extension, BinDiff is automated from within Ghidra, so you don't have to diff your binaries yourself.

• BinDiff the binary opened in Ghidra with another binary from the same Ghidra project, show results and import function names
• Open a BinDiff file, created with BinDiff 6, from two .BinExport files and import the matching function names in Ghidra

• Fix a bug where the file to import to needed to be checked out.
• Increase size of project file selection dialog

• Import function names and function parameters (type and name)
• Compare the binary opened in Ghidra with an external .BinExport (from IDA for example)
• Communication with the BinDiff 6 GUI to show graphs for the different functions

Either download the .zip-File from the release, if it's compatible to your Ghidra version, otherwise see How to build below.

Open Ghidra, go to File->Install Extensions... in the Main Window. Click the +-Button in the top right and select the BinDiffHelper zip file.

Close the plugin manager. Restart Ghidra to load the new plugin.

• BinExport plugin binaries or compiled from source for your specific Ghidra version
• BinDiff 6 (https://zynamics.com/software.html)

Without these, you will only be able to import .BinDiff files and not automatically export and diff from your Ghidra project

Make sure the plugin is loaded in the Code Explorer by opening a file in Ghidra and in the Code Explorer go to File->Configure

Click the small plug-icon in the top right:

and make sure the checkbox next to BinDiffHelperPlugin is checked.

The corresponding .BinExport-Files need to be in the same Folder.

Open the file you want to import names into in the code Browser, then go to Window->BinDiffHelper

Use the Open from BinDiff button or menu item and select your .BinDiff file.

Select all the function names you want to import and click the Import function names button in the top right or the menu item.

Go to Window->BinDiffHelper, make sure there are no warnings concerning BinExport or BinDiff, then click the Open from project button.

Select the other file from the tree and click OK.

Requirements:

• Ghidra installation (https://ghidra-sre.org) or compiled from source
• some jdk (if you built Ghidra yourself, it needs to be the same jdk)
• gradle (tested with 5.0 and 6.2.2)

You need to set the GHIDRA_INSTALLATION_DIR environment variable to the Ghidra installation dir. If you have different JDKs installed, make sure the environment variable JAVA_HOME points to the one your Ghidra installation uses.

The extension will be built for that Ghidra version specifically.

And then go the BinDiffHelper folder in your shell and do

gradle

There should have been a .zip-File created in the dist directory.

Use that .zip File to install according to the instructions above.
