BromaIDA

IDA Broma support (now real).

Parses a Broma file and exports the bindings into a Broma file/imports the bindings into the current IDA project.

Requirements

• IDA 7.0 or higher
• IDAPython
• Python v3.10.0+ (tested with v3.11.9)
• PyBroma
• If you want to be able to import types:
  • IDAClang
  • STL Headers (see Importing Types Requirements)

Features

• Importing
  • Import function names
  • Import types (see Importing Types Requirements). If enabled, will do the following:
    • Import Broma classes members, virtual functions, etc...
    • Import function return types
    • Import function arguments types and names
    • On Android binaries, fixes IDA completely messing up the arguments of functions for no reason
• Exporting
  • Export function addresses for any platform
  • Export function return types (if enabled, see BromaIDA Settings)
  • Export function arguments' names (if enabled, see BromaIDA Settings)

Installation

1. Get python, then git clone https://github.com/CallocGD/PyBroma --recursive, cd PyBroma then finally python .\setup.py install to install PyBroma (blame CallocGD for breaking pip install https://github.com/CallocGD/PyBroma/archive/refs/heads/main.zip)
2. Download the release/zip file
3. Copy BromaIDA.py and the broma_ida folder into IDA_DIRECTORY/plugins

Usage

1. Ctrl-Shift-B, or from the Top Bar (Edit -> Plugins -> BromaIDA) to start importing/exporting
2. Browse and select the Broma file
3. Let the script handle the rest and enjoy free/exported bindings

Importing Types Requirements

• To import types:

  • You must have IDAClang.
  • You must have the STL headers for the target platform (MSVC headers for Windows binary, GCC headers for the others). You can however use MSVC headers on binaries that aren't Windows (but not the other way around).
  • Extras.bro must be in the same directory as the imported Broma file

• Get your STL Headers path (on Windows)

  • For Windows binary (or if not using custom GNU STL)
    1. Get MSVC Headers by installing MSVC using the Visual Studio Installer
    2. Your header path should be C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.40.33807\include
  • For Android binaries (Android 64 and 32 bit)
    1. First get gcc-arm-none-linux-gnueabihf (i did so by using scoop; scoop install extras/gcc-arm-none-linux-gnueabihf)
    2. Your header path should be C:\Users\YOUR_NAME\scoop\apps\gcc-arm-none-linux-gnueabihf\current\arm-none-linux-gnueabihf\include\c++\13.3.1;C:\Users\YOUR_NAME\scoop\apps\gcc-arm-none-linux-gnueabihf\current\arm-none-linux-gnueabihf\include\c++\13.3.1\arm-none-linux-gnueabihf;C:\Users\YOUR_NAME\scoop\apps\gcc-arm-none-linux-gnueabihf\current\arm-none-linux-gnueabihf\libc\usr\include;C:\Users\YOUR_NAME\scoop\apps\gcc-arm-none-linux-gnueabihf\current\lib\gcc\arm-none-linux-gnueabihf\13.3.1\include (be sure to replace YOUR_NAME with your windows username)
  • For MacOS (Intel and M1 Mac) and iOS binaries
    1. First get gcc (i did so by using scoop; scoop install gcc)
    2. Your header path should be C:\Users\YOUR_NAME\scoop\apps\gcc\current\include\c++\13.2.0;C:\Users\YOUR_NAME\scoop\apps\gcc\current\include\c++\13.2.0\x86_64-w64-mingw32;C:\Users\YOUR_NAME\scoop\apps\gcc\current\x86_64-w64-mingw32\include (be sure to replace YOUR_NAME with your windows username)

1. Launch the BromaIDA plugin using Ctrl-Shift-B, or from the Top Bar (Edit -> Plugins -> BromaIDA)
2. Click on the Settings button
3. Follow the steps above to get and get your STL Headers path (be sure to check "Import Types")
   • Once you get your STL Header path, paste it in the correct folder input. ("MSVC STL Directory" for MSVC, ...)
   • If you aren't using custom GNU STL, be sure to uncheck "Use Custom [Android/Mac] GNU STL".
   • If you are using custom GNU STL, be sure to check "Use Custom [Android/Mac] GNU STL", otherwise you won't be able to select the custom GNU STL path.
4. Exit out of the settings window

Start the script and the plugin will handle everything :)

BromaIDA Settings

Can be accessed through the main popup by clicking on the "Settings" button. This replaces the old "ask everything everytime" method.

Here you will find some options you can set, such as importing types, settings default parser parameters, etc... The options you chose will be saved into a shelf stored in the IDA_DIRECTORY/plugins/broma_ida folder.

Utilities

This section is meant for people who want to contribute.

In the utils folder, you can find some utilities that can help in contributing.

• Currently has:
  • tasks.json: To be put in /BromaIDA/.vscode, adds 2 tasks for VSCode. "Install Plugin" will copy BromaIDA.py and the broma_ida to the IDA_DIRECTORY/plugins directory; And "Launch IDA v8.3" which will launch IDA (shocker). Just be sure to replace IDA's directory with your IDA installation directory.

Thanks

• Special thanks to:
  • The IDAPython API: Used for everything.
  • CallocGD's PyBroma: Used to parse imported Broma files.
  • @sleepyut: Issuing 3 trillion bug reports. Also for suggesting a bunch of features. (they also made BromaBJ)
  • AngelDev06: Contributing features.
