PyQBDI 0.11.0

Python binding for QBDI

Introduction

QuarkslaB Dynamic binary Instrumentation (QBDI) is a modular, cross-platform and cross-architecture DBI framework. It aims to support Linux, macOS, Android, iOS and Windows operating systems running on x86, x86-64, ARM and AArch64 architectures. In addition of C/C++ API, Python and JS/frida bindings are available to script QBDI. Information about what is a DBI framework and how QBDI works can be found in the documentation introduction.

QBDI modularity means it doesn’t contain a preferred injection method and it is designed to be used in conjunction with an external injection tool. QBDI includes a tiny (LD_PRELOAD based) Linux and macOS injector for dynamic executables (QBDIPreload). QBDI is also fully integrated with Frida, a reference dynamic instrumentation toolkit, allowing anybody to use their combined powers.

A current limitation is that QBDI doesn’t handle signals, multithreading (it doesn’t deal with new threads creation) and C++ exception mechanisms. However, those system-dependent features will probably not be part of the core library (KISS), and should be integrated as a new layer (to be determined how).

* The ARM and AArch64 instruction sets are supported but in early support.

Installation

Python API (PyQBDI)

PyQBDI is available through PyPI. The wheel package can be either downloaded or installed with the following command:

pip install PyQBDI

The PyQBDI package is self-contained so completely independent from the C/C++ package.

Devel packages

There is no strict development timeline or scheduled release plan for the QBDI project. All the new features and fixes are merged onto the dev-next branch. Devel packages can be downloaded in the artefacts of:

• Github Actions for Linux PyQBDI

• Github Actions for OSX PyQBDI

• Github Actions for windows PyQBDI

Compilation

The PyQDBI library (apart from the wheel package) can be built by solely passing the ‘-DQBDI_TOOLS_PYQBDI=ON’ option to the CMake build system.

However, if you want to build the wheel package, you can run these commands:

git clone https://github.com/QBDI/QBDI.git
python -m pip install --upgrade pip
python -m pip install setuptools wheel build
python -m build -w

A 32-bit version of Python is mandatory for the X86 architecture whereas a 64-bit one is required for the X86-64 architecture.
