Quokka is a binary exporter developed by Quarkslab. It serves the same purpose than BinExport but it exports more data like data references that Binexport does not. The goal is to approach the disassembler functionalities in terms of available information.

It has also been designed with space efficiency in mind. The goal is to have a minimal overhead in comparison to other exports or disassembler databases (e.g: .i64) so that they can be kept along with the binary. Everything that can be retrieve from the static executable file will be (strings, data, etc). Also Quokka leverages the variable integer length encoding of protobuf to reduce their size as much as possible.

A thorough comparison of time, and space differences between Quokka and other exporters have been done in this blogpost.

Quokka: A Fast and Accurate Binary Exporter


Quokka is a binary exporter: from the disassembly of a program, it generates an export file that can be used without the disassembler.

The main objective of Quokka is to enable to completely manipulate the binary without ever opening a disassembler after the initial step. Moreover, it abstracts the disassembler’s API to expose a clean interface to the users.

Quokka is heavily inspired by BinExport, the binary exporter used by BinDiff.


Python plugin

The plugin is built in the CI and available in the registry.

It should be possible to install directly from PIP using this kind of commmand:

$ pip install quokka-project

IDA Plugin

Note: The IDA plugin is not needed to read a Quokka generated file. It is only used to generate them.

The plugin is built on the CI and available in the Release.

To download the plugin, get the file named quokka_plugin**.so.


Export a file

!!! note

This requires a working IDA installation.
  • Either using command line:

$ idat64 -OQuokkaAuto:true -A /path/to/hello.i64

Note: We are using idat64 and not ida64 to increase the export speed because we don’t need the graphical interface.

  • Using the plugin shortcut inside IDA: (by default) Alt+A

Load an export file

import quokka

# Directly from the binary (requires the IDA plugin to be installed)
ls = quokka.Program.from_binary("/bin/ls")

# From the exported file
ls = quokka.Program("ls.quokka",  # the exported file
                    "/bin/ls")    # the original binary



user@host:~/quokka$ cmake -B build \ # Where to build
                          -S . \ # Where are the sources
                          -DIdaSdk_ROOT_DIR:STRING=path/to/ida_sdk \ # Path to IDA SDK
                          -DIda_BIN_DIR:STRING=/path/to/ida/dir \ # Path to IDA
                          -DCMAKE_BUILD_TYPE:STRING=Release \ # Build Type
                          -DBUILD_TEST:BOOL=OFF # Don't build the tests

user@host:~/quokka$ cmake --build build --target quokka_plugin -- -j

To install the plugin:

user@host:~/quokka$ cmake --install build

In any case, the plugin will also be in build/quokka-install. You can copy it to Ida plugin directory.

user@host:~/quokka$ cp build/quokka-install/quokka*64.so $IDA_BIN_DIR/plugins/
